Popul tion and Poverty: A Review of the Links, Evidence and Implications for th Philippines* ANICETOC. ORBETAJR.**

Introduc

on

The relati nship between demographic changes and poverty is an old issue that has gained currency because of the recent focus of governments, m ltilateral agencies, and other development organizations on poverty al eviation. For the Philippines, all of the post-Martial Law governments have made poverty alleviation their centerpiece program.

Analysts h ve been trying to understand why, in spite of this consistent focus, gai s in poverty alleviation in the country have been modest.

The most accepted explanation, being the most obvious perhaps, is the uneve economic growth performance. However, it is wellknown, although eavily debated upon, that demographic factors play an important r e not only in poverty alleviation but even in economic growth as well. P oviding a systematic clarification of this role is the objective of this pa er. Such clarification may well inform discussion on the role demogra hic changes play on poverty alleviation efforts in the country.

velop ent, the experience of the Philippines and Thailand in the past 40 ye rs is briefly compared in the following section. This is then followed by a description of the known links between demographic chan es and poverty. Then a section where empirical evidence of the links re reviewed follows. The final section draws some implications for p licy.

Tre Popul

in population and poverty tion change and its components

Popul tion change can be divided into changes in size, structure, especia y age structure, and distribution across space. This is easily derivabl from the mathematical identity that changes in population size can c me from either births, deaths, or net migration. An empirical regul rity, known as the demographic transition has been long observed by de ographers. This.is characterized as consequent on, and later on also c using, falling child mortality is followed by falling fertility. Accordi gly, at the first stage, population growth rises because of a decline n mortality, which is usually distributed almost evenly across age grou s, with fertility remaining high. At this stage, the youth dependen ratio will be high. In the next stage, fertility starts to fall with mor lity starting to settle at a low level so population growth will start to de line. In this stage, the youth dependency ratio will start to go down Finally, both fertility and mortality will be low and remain low and p pulation growth also low. This will be accompanied by high oldage d pendency ratio. The period where the youth dependency starts to de line, which also means an increasing proportion of economically ctive population, provides a window of opportunity for the socalle "demographic bonus" that can spur economic growth. This is now ne of the familiar explanations to the East Asia high economic grow h phenomenon in the past two decades (e.g., Bloom and Willi mson 1998).

ors. Thailand and Indonesia, for instance, reduced their growth 0 1.4 and 1.6, respectively, in the 1990s. Consequently, in comn to Thailand that almost had the same population size in 1965, untry had about 14 million more people around year 2000.

Fertili y

Data how what appears to be a fairly rapid decline in fertility in the 1970s This was stalled in the 1980s and 1990s and lately even showed signs f a slight increase. Total fertility rate (TFR) declined from about 6 at t e beginning of the 1960s to 3.6 by the middle of 1990s. This trend in fertility reduction is slow by East and even Southeast Asian stand rds (Table 2). Starting with about the same TFRs at the start of 1960s Thailand and Indonesia had reduced their TFR to 2.1 and 2.6, respe tively, by the middle of 1990s.This means a longer catch-up time to fer ility levels already achieved by the ASEAN neighbors.

Marta lity Morta ty, measured either as Crude Death Rate or Infant Mortality Rate, snowed rapid decline during the early post-war period because of ad, 'ances in public health and rapid economic development. This declir e has slowed down in the recent past as low levels of mortality or high evels of life expectancy have been achieved. This is clearly depictec by the developments in infant mortality rate (IMR) (Table 2).

With :ne uneven economic performance, the slow decline of the IMR in the Philippines is to be expected (De Guzman 1998). Thailand with a con: Ilstent high economic growth rate, was able to sustain lower infant nlortality rates than the Philippines through out the post-war period. ~outh Korea, starting with a low, but not too far below, level of IMRi [l 1960-65, achieved an even faster decline. )ased on the above trends in fertility and mortality, the Philippine )opulation growth rate is understandably higher than many of our nl:ighbors. It is also clear that since our fertility remains high, the only t.1ing that prevented the full impact of that on population growth is tha our uneven economic performance has prevented us from achie'ring even lower mortality rates. What is disturbing, and may be unknc)wn to many, is that the continued high fertility rates will also mean long years of high youth dependency burden, which will rob us of th ~ window of opportunity for the demographic bonus that allowed other East Asian countries to increase their savings rates, physical and hum capital investments that spur their economic growth in the last

two d~cades. Herrin and Pernia (2000) describes what we continue to bear ~s "demographic onus" rather than a demographic bonus.

Defini ion and measuresofpoverty Ther are many issues in poverty measurement. This paper will focus only n the main issues being discussed for the Philippines.2 The official p verty statistics uses current income as the basis for computing pover y incidence. Balisacan (2001) argues that current consumption is bet er than current income as the basis for measuring poverty from both onceptual and practical grounds. He further argues that income can u der- or overestimate living standards through borrowing and savin. Furthermore, he says that welfare level is determined by "lifecycle" or "permanent" incomes and current consumption is a better meas re of this income. Finally, income is much more difficult to obtain a d more prone to underreporting. Self-rated poverty, which is depe dent neither on incomes nor on consumption but on qualitative s If-assessment,has also been proposed by Dr. Mahar Mangahas of the S cial Weather Stations. here are also multidimensional measures of well-being. One that has g ined local official acceptance is the so-called minimum basic needs indicators. This consists of several indicators3 grouped into three, name y: survival, security and enabling. Reyes (2002) briefly describes its pr venance in her paper. Another multidimensional measure of well-b ing that has gained international acceptance is the Human Develop ent Index (HDI) developed by United Nations Development Prog mme. This is based on four indicators: 1) life expectancy at birth; 2) fu ctionalliteracy and the 3) combined elementary and high school enrol ment ratio; and 4) real per capita income.

Trend in poverty alleviation The rogress in poverty alleviation in the country is modest (Reyes 2002). In fact the number of the poor has not declined but even increas d from 4.6 million in 1985 to 5.14 million in 2000. In addition, the r duction in poverty incidence is only happening in urban areas.

Whil the poverty incidence in urban areas declined by 14 percentage poin between 1985 and 2000. the corresponding number for rural

areas is nly 4 percentage points (Table 3). There also remains a wide disparity of poverty incidence across geographic areas. For instance, in 2000, it stood at almost 66 percent in the Autonomous Region of Muslim indanao (ARMM) and 55 percent in the Bicol region as against nly 9 percent in the National Capital Region. Variation at the provinci 1 level is even more pronounced.

Inc me inequality has not improved either. The share of the poorest quin .le has even declined from 4.8 percent in 1985 to 4.7 percent in 2000 Reyes 2002). The share of the richest quintile, on .the other hand, in reased from 51.2 percent to 54.8 percent over the same period. In ddition, the Gini concentration ratio also went up from 0.47 in 1985 00.51 in 2000 (Figure 1).

Th Asian crisis experience has also shown that the Philippine populati n is vulnerable to shocks as gains in poverty alleviation during the arlier periods were easily reversed during the crises.

OF DEVELOPMEN째

The poverty decomposition analysis of Reyes (2002) reveals that for the period 1985-2QOO, the contribution of the growth component was larger than the distribution componenL The growth component contributed a 16.5 percentage-point reduction in poverty incidence but the worsening of the distribution increased it by 4.7 percentage points, resulting in a net decline of 9.4 percentage points with 2.4 percentage points classified as residual.

Table 4 shows that our poverty reduction record, compared to those of our neighboring countries and using the US$l a day poverty threshold, is slower. In addition, most of these countries were able to reduce the number of people living in poverty. In terms of the HD!, our neighbors have also over taken us (Table 5).

A digression: population and development in the Philippines and Thailand To illustrate the role of demographic changes in development, this paper compares briefly the socioeconomic development of the Philippines and Thailand in the last 40 years. Table 1 shows that both had about 31 million people in 1965. In terms of per capita income in real US$, however, the Philippines had $725 while Thailand had only $465 (Table 6). Forty years later, the latest estimate of Philippine population is 76.5 million, nearly 14 million than Thailand's 62.8 million. In terms of per capita income, Table 6 shows that Philippines had 1,167 real US$ while Thailand had 2,805 US$ in 2000 or almost 2.5 times.

The deve opments of these two indicators over the years are shown in Figures 2 and 3. While it would be wrong to attribute all of this difference to emographic changes, comparing the two in this area would provide useful background for the succeeding discussions.

The big difference between the two countries lies in the divergence in fertility levels, with Thailand being able to bring down its TFR to a eplacement level of around 2.1 at the beginning of the 1990s compare to the Philippines' more than 4 at the time and still over 3 per wom n today (Figure 4). There is not much divergence in terms of infant ortalityas both countries were able to reduce their mortality levels n a very similar fashion, with Thailand protecting her initial advantag all throughout the period (Figure 5). The difference in fertility leve s spawned not only a divergence in population growth and populati n size (as discussed above) but also a glaring deviation in youth de endency burden, as shown in Figure 6. Given that the fertility rates re hardly closing, this difference in dependency burden is sure to ontinue for more years. Among the known impact of high depende cy burden is that it depressessavings and, consequently, physical as well as human capital investments. Figures 7 and 8 show that indeed s vings and investments have deviated since mid-80's. Finally, in recen years Thailand has begun to surpass the Philippines even in investme ts in human capital, which is evident in part in its enrollment'rat os in both secondary and tertiary levels, which have exceeded the latte ' s (Figure 9).

Populati n and poverty: a description of the links To descr" e the links between population and poverty, this paper deems it best to tart with the Population and Sustainable Development Framework (PS F), as presented in the 2001-2004Philippine Population Management Program Directional Plan (Figure 10) and explained in greater

detail in errin (2002). Starting with this framework provides one with a compre ensive view of the relationships between population change and the d fferent dimensions of development, one of which is poverty.

Essentiall , the framework shows that demographic processes (fertility, morta ity, and migration) and outcomes (size, structure and distribution) ect productive capacities (natural resource and environment, hu ary resource) and outcomes (goods and services provision and cons mption), which are translated into measures of wellbeing (health, utrition, education, desired fertility, etc.). In turn, these development outcomes affect demographic processes and outcomes.

This paper focuses next on the mechanisms through which population ch nges affect poverty. While not explicitly depicted, it would soon be c ear that this is subsumed in the framework.

OF DEVELOPMENT

here are three main channels through which population affect pover .4Following the taxonomy in Eastwood and Lipton (1999,2001), these re: the growth, distribution and conversion channels. The growth chan el refers to the impact of demographic variables on the level or growt of attainable welfare per person, usually measured by mean in co e or average consumption, given the distribution of income. The distri ution channel refers to the impact that alters the distribution of inco e, given the attainable welfare per person. The conversion channel r fers to the changes in actual wellbeing or capabilities, given the attain ble welfare per person. In terms of the PSDF, the growth channel r fers to the impact on the middle box; the distribution channel, on th impact on the elements of both the middle and the right boxes; and t e conversion channel, on the right box. Eastwood and Lipton (2001) point out that, among the three, only the, growth channel has recei ed considerable attention compared to the other two. he ,growth channel refers to the impact of demographics on mean income or average consumption. Based on the production function oncept, the discussions on the growth channel focus on the impact n the means of generating income or factors of production,

namely, p ysical and human capital as well as technology and productivity. Thi is usually discussed in two levels, the macro or aggregate level and he micro or household level. At the aggregate level, the issues rev lve ,around the impact of population changes in the aggregate accu ul~tion of physical and human capital. Central to the discussion is he iimpact on savings, because it finances investments. The impact on aggregate investments on human capital such as education and healt ,has also been given ample attention. Finally, on the role of popula .on changes on the development of technology and productivity, e ,central question is whether population changes affect the develo m~nt of technology and thereby affect productivity. At the household level, similar issues are relevant for almost identical reasons.

What are the mechanisms in the distribution channel? Even if relatively I ttle work has been done in this area this issue has a long history. Ea twood and Lipton (1999) trace the origins of the income distributio ef:fect of higher fertility to Malthus. He hypothesized that at the agg egate level, high fertility would raise the price of food and lower the rice of labor. Since the main assetof the poor is his labor, this is exp cted to affect the distribution of income. Eastwood and Lipton (19 9,2001) identify two groups of ways through which demographics a fect inequality and poverty. These are the dependencyeffect and the a quisition effect. These two subsume the aforementioned Malthusia effect. The dependency effect refers to the hypothesis that higher fer ility worsens the distribution of consumption if the extra births are n4entrated in the poorer households, raising dependency ratios amo g the poor disproportionately. The acquisition effect, on the other and, refers to the worsening of consumption distribution via the abi ity or willingness of nondependents to acquire income or via their sa .ngs behavior and factor rewards. The key to the distribution effect i differential impact on the poor vis-a-visthe nonpoor households. Thu , the distribution effect can be viewed both at the aggregate and h usehold levels.

Dwell ng further on the acquisition effect, this paper expresses it in four wa ,namely: I) child costs, 2) labor supply, 3) savings, or 4) factor rewa dsJ Child costsrefers to added costs due to the presence of an extra c ildj such as the direct or opportunity cost of child care.

Additional ependents in a household may induce greater labor supply from n ndtpendents. Fertility may affect household accumulation.

While initi lly the effect of an additional child on household labor

210

PHXLIPPINEjOURNAL

OF DEVELOPMENT

sup ly is indeterminate due to the opposing negative effect via deman s for child care and positive effect due to induced labor supply, over time the child enters the labor force and increase household labor upply. This may depress real wages for the poor who tend to be uns illed compared to the rich-the Malthusian effect.

Finally, what are the mechanisms in the conversion channel? As note earlier, this channel refers to whether demographics affect the cap ity to transform a given income or consumption expenditure level into welfare or capabilities such as health and schooling. Necessarily, this ffect will primarily have to be viewed at the household level. Again, like he distribution effect, this is also dependent on differential behavi r between the poor and the non poor households. The key issues her include: 1) whether a large family is a rational choice for the poo ; 2) if the economies of scale in consumption are more important tha sibling crowding; 3) if children in large households enjoy worse edu ation and health care prospects; 4) whether getting out of poverty becomes easier or more difficult by extra births.

Three more concerns have to be mentioned on the relationship be een population and poverty. These are differential demographic tran ition, mutual causation, and intergenerational transmission. Dif fer; tial demograPhictransition refers to the observed regularity that the poo usually experience declining mortality and subsequently falling fert.lity later, and with a longer lag between them, than the nonpoor.

Thi has significant implications on the distribution and conversion effe ts. Mutual causation refers to the fact that rapid population gro th-early first births, large families, high child-adult ratios and clos r spacing of siblings-may not only be a cause but also a conseque ce of poverty due largely to constraints on and even the rational beh vior of the poor. This has troubled empirical tests on the relationshi between demographic changes and poverty.

Finally, inte generational transmission of poverty and inequality has been cited as a very important welfare issue. Lam (1987), for instance, is not as stro g on the other of aspects of the impact of demography on inequ lity but identified this issue as very important. His basis is the wellacc pted negative impact of high fertility on child endowments (inclu ing human capital). Incidentally, this has also been identifies as the basis for the intergenerational vicious cycle of poverty argument trig ered by high fertility rates among the poor.

The relati nship between population change and the level and growth in per ca ita income has been the subject of scrutiny and a long-drawn debate. T e assessmentin the 1980s qualified the strong negative impact verd ct in the 1970s. For instance, a more calculated assessment exemplifi d by the statement from the National Research Coun<;il (1986) s tes that "on balance, we reach the qualitative conclusion that slow population growth would be beneficial to economic development ÂŁ r most developing countries." More recent empirical results utilizing c nvergence-pattern or technology gap models such as Kelly and Sch idt (1995, 2001), however, yielded large negative impact of populatio change on growth of per capita income. In particular, a study by elley and Schmidt (1995), using data covering a 30-year period (196 1990), finds that a unit decline from recorded median population gro th rate of 2.54 to 1.54 percent results in an increase of per capita GN growth from its median of 1.36 to 2.00 percent. High crude birth rate were found to reduce economic growth while decreases in crude dea h rates increase economic growth. A survey and re-estimation of ei ht models incorporating several economic-demographic approach s given in Kelly and Schmidt (2001) validates this earlier result. Th survey highlights the following results: 1) demographic trends (d clining population growth, fertility, mortality; changing age distributi n; and rising density and population sizes) have sizeable impact 0 economic growth; 2) while the overall impact of population grow h is negative, fertility and mortality effects have offsetting effects wit increases due to mortality decline stimulating growth while increas ue to rise in fertility attenuating growth; 3) increasing densities an opulation size contribute a positive but relatively small boost to econo ic growth, with scale effects dominating density; 4) in most models, e impact of demography has declined over time.

It is orth noting that the role of changing age structure accompanying d mographic change was found to have a considerable explanatory ower to rapid economic growth in East Asia in the past two decades. hus, it is argued that population neutralism of the 1980s maybe w the offshoot of the too much focus on impact of aggregate populatio growth to the neglect of the impact of changes in the age structure Bloom et al. 2001). It is also argued that in the early stages

212

of th demographic transition, per capita income declines because of large outh dependency burden and a small proportion of workingage a ult working and saving. As the transition proceeds, per capita in co e increases as the share is reversed with relatively more workers and s verso This constitutes a potential window of opportunity, now popu arly known as the "demographic bonus," which will evaporate as the s are of the elderly rises in the later phase of the transition. Simulatio s done by Lee et al. (2001), using data from Taiwan, validated the h pothesis of increases in savings rates as the proportion of working a e population increases under the assumption of constant interest ra e ~nd constant productivity rate. Bloom and Williamson (1998) find a~ population dynamics explain as much as 1.4 to 1.9 percentage oillits of the GDP per capita growth in East Asia, or as much as one- ird of the average East Asian miracle GDP per capita growth rate 1.9(6.1). In Southeast Asia, the estimated effect ranges from 0.9 to 1. points of economic growth or about half (1.8/3..8) of the record d g)rowth in GDP per capita. Finally, Eastwood and Lipton (2001) esti te that had the average country5 reduced its birth rate by five per t ousand throughout the 1980s, the average poverty incidence woul have been declined from 18.9 percent in the mid-1980s to 12.6 perc nt between 1990 and 1995. About half of this reduction is attributabl

to increases in economic growth. irnulations using the Population and Development Planning (PD ) Model, an economic-demographic model estimated using Philippi e data, also show that higher population growth lowers GNP per capit level (Orbeta et al. ~999). Furthermore, this negative effect was foun to be much bigger if foreign capital inflows are held fixed.

A l~ok at the growth performance of countries in Asia shows that the ilippines had lagged behind Thailand, which had about the same pop lation size and even lower per capita income in 1965. Thailand's pop ladon is growing at less than one percent while that of the Philippine is ~till growing at more than 2 percent. As a result, after 35 years the hil~ppines has about 14 million more people and about less than half fThailand's per capita income.

As noted earlier, growth in per capita income is also affected by phys cal:and human capital investments. At the macrolevel, it wasfound~ "The d~taset includes 45 less developed and transition countries.

that incre sed human capital expenditures (aggregate expenditures on educa ion and health) spawned by rapid population growth are insufficie t to maintain per capita levels, which implies negative impact on e ucation and health output (Orbeta 1992).

At t e hpusehold level, Herrin (1993) finds that accumulation of househol assetsis negatively affected by the number of young children 0 to and 7 to 12 years old. This result is corroborated by Mason (1992). T e study finds that child bearing negatively affects the saving rate. Alth ugh it does not affect the absolute am~unt of savings, asset per child as found to be greater in lower fertility households.

Distributi effects As has be n mentioned earlier, there has not been as much work on this chan el compared to the growth effects. In an earlier review, Lam (1987) no es that empirical evidence leads to mixed conclusions. Furthermore the review emphasizes that the "certainty of negative distributional e fects of population growth expressed in the 1974World Bank report on population and development. ..seems to be a much stronger concl sion than the empirical arid theoretical analysis of the issues can c rrently support."

Utili ins newer modeling ideas, recent results such as Eastwood and Lipt n (1999; 2001), provide more definitive conclusions. The study not onlry found that high fertility retards economic growth (as noted ab ve) but also skews the distribution of income against the poor. Th ir estimate revealed that half of the estimated decline in poverty c uld be attributed to increases in economic growth and half to chang s in the distribution of income. The results further highlighted th fact that as fertility decline spreads to poor households, the pover -reducing benefits of fertility decline increase even more.

Reinforci g this result are similar findings in Brazil, a country that is in the lat r stages of fertility transition (Paes de Barros et al. 2001).

Dependen In trying Lipton (1 dependen slight dep be only sl.

effects 0 find evidence of the dependency effect, Eastwood and 99) used 18 of the 56 World Bank Poverty Assessments on y ratios for the poor and nonpoor. The data show only a ndency effect as the dilution ratio of the poor was found to htly higher than those for the nonpoor.

Acqui 'tion effects In ter s Qf acquisition effect, studies on the impact of additional children n ~me allocation show that the mother's labor market hours decli e 14 months after giving birth, after which they return to the pre us level; the father's labor market hours are not affected, neithe oes the loss of the labor market hours of the mother induce more abor market hours for the father; the labor market time of the older aughter, however, increased (Tiefenthaler 1997). It appears that the 01 er' daughter replaces the lost market time of the mother. Earlier st dies both support and negate results of this finding. For instanc , Quizon-King (1978) finds that the labor market time of both moth r and father is not affected and only the mother's home time incre ses. This is largely corroborated in King and Evenson (1983).

Garci (1990), on the other hand, finds that having young children decre es the market time of the mother but increases the market time of the father. n the labor force participation of older children, a joint schooling-la or!force participation model for children 10 to 24 years old was estim ted using a merged Family Income and Expenditure Survey (FIES , Labor Force Survey (LFS) and Functional Literacy Education and assMedia Survey (FLEMMS) for 1994 in Orbeta (2000). He finds that ÂŁ mily size does not significantly affect school attendance but positively afft:cts labor force participation. Corroborating this result, Villa il (f2002), using the 1995 Child Labor Survey, provides evidence that t e probability of children 5 to 14 years old not going to school but w rking is positively related to the number of young children (0-9 years) but is negatively related to the number of older children (15-17 years) in the family. n the aspect of the impact of rapid population growth on wages, Bloo and Freeman (1988) find that for the period 1965-1985, developing countries were able to shift the labor force from low productivity ag iculture to higher productivity industry and services sectors despite he rapid growth of their population. This shows that there may not b much depressing impact on wages. They caution, however, that such djustments may become increasingly difficult in the future. In the c se of the Philippines, studies (e.g., de Dios et. al. 1993) reveal slow rowth in employment opportunities. This is further buttressed by th high open unemployment and underemployment rate that did not s are even educated workers (Orbeta and Pernia 1999). Finally, the c ntinued flow of overseas contract workers is testimony to the

lack of e~ PIOyment opportunities domestically. All of these indicate that the althusian negative impact of rapid population growth on poverty vi the distribution effect may be operating.

Conversion efftcts While pri arily the evidence on conversion effects would come from household le~l analysis,there are indications that can be gleaned from the aggre ate!level. For instance, there are countries where per capita incomes 0 p~r capita consumption are lower but indicators of wellbeing are be1Jterthan those with higher incomes. Sri Lanka, for instance, ha lower per capital income than Indonesia, the Philippines, and Thail nd (Table 6), but it has better infant mortality record and school att ndance, particularly at the secondary level. We now turn to the house old-level evidences.

Fertility pr; erences An empiri al regularity one finds worldwide is that poverty incidence is always h gh~r among households with larger family size. The Philippines is n e~ception, as shown in Table 7, The question is whether the poor atiÂŤ)nally choose to have large families, There are indeed conceptua reasons and even empirical evidence that the poor may prefer to ave large families, These could be any or a combination of the follow'ng: they put high value on the perceived benefits of having many chil ren; they put low value on the costs of having them; or they find small rQbability in enjoying the alternatives, Amo g the commonly cited reasons are that children add to family incom , provide old-age security, and that fewer and better-educated chil ren with better earning prospects may be just a remote'option for th poor, The reasons could include requiring what to them could be naffordable savings, delayed (or heavily discounted) and risky retur s, ~nd very high opportunity cost from foregone child laborincom, How ver, Birdsall et aI, (2001) challenge the belief that the poor rationally hopse to have large families and require proofs on the following wh ch,! which have been highlighted by recent studies: 1) that the choice off the poor are not limited; 2) that the poor have the required inp ts to make an informed choice; 3) that men do not dominate the c oice over the number of children while not fully sharing the costs; (d) that there is no higher prevalence of unwanted pregnancies amon the poor compared to the nonpoor; and 5) that fertility

has i creased among the very poor who have good access to health and ÂŁ: mily planning information and services. It would require intensive t ststo know the answers to these questions. However, the answers may e g~eaned from available data on the Philippines. able 8 shows the differential contraceptive practice of the poor and t e monpoor. It must be noted that the classification, due to data limi tions, may be a bit loose. But if contraceptive practice is an indicatio Ofithe extent of control over fertility, the table shows that, from eithe thie actual contraceptive practice or access to family planning servi es, ,the poor may have less control over their fertility than the nonp or, Using a finer disaggregation of households, Table 9 shows that he disparity in the use of modern contraceptives by poor and nonp 011households is even more pronounced. If accessand contracepti e practice were even for both the poor and the nonpoor, then the p or, as shown in Table 6, could have large family size by choice.

Final y, tpe evidence on unwanted fertility and unmet need for family plan ing points to the disparity between the poor and the nonpoor.

Pam 111 and Ramosjimenez (2000), using the 1993 National Demograp ic Survey (NDS), the 1998 National Demographic and Health Surv y (NDHS) and a wealth index, show that women in the poorest 20 pe ce~t of households are 27 percent more likely to have unwanted fertil ty and 122 to 154 percent more likely to have un met need6 for famil pl!inning compared to women in the richest 20 percent of household .T~ble 10 shows a similar story using data from the recent 2002 roun of the Family Planning Survey. The table shows that women from the p orest households have almost twice as much prevalence of unmet need for family planning as do women from the richest households.

Econ mitis of scalein consumption On t e aspect of economies of scale in consumption, evidence on both sides of the argument exists. It has been shown that the negative impact n consumption of large family size will not hold under some plaus'bl~ assumptions about economies of scale in consumption (e.g.

Lanj w ctnd Ravallion 1995 for Pakistan; Anand and Morduch 1996 for Bang ad~sh). But there are also pieces of evidence on the congestion effec .King (1987), for instance, notes crowding in the poor's small dwel ings.

Investmens in human caPital Empirica evidence that high fertility is associated with decreasing investmen in education and health abounds. King (1987) provides a review 0 studies on the effect of population change on household welfare. he conclusions include the followmg: 1) children in large families erform worse in school; 2) children in large families have poorer haIth, lower survival probabilities, are less developed physically; 3) i pact on parental welfare is not as clear. These conclusions are subst ntially echoed in a more recent review of studies with some added di ensions (Lloyd 1994). In particular, the study found that the adver e impact on children born into large families can be grouped into: 1) r source dilution, with each child getting a smaller share of family re ources, including income, time, and maternal nutrition; 2) the "opp rtunity effect" through diminished accessto public resources, such as h alth care and education; 3) the "equity effect," which means unequal distribution of resources among siblings; and 4) the "intergen rational effect," with the adherence to the traditional role affecting e transmission of opportunities to the next generation.

Orb ta (2002) reviews several more studies showing similar results in th Philippines. High fertility does not affect school participation of yo nger children (7-12 years old) but negatively affects school participa on and attainment of older 13-17years old children (Herrin et al. 199 ). Bauer and Racelis (1991) corroborate this result on older children. eGraff et al. (1993) particularly emphasized the large negative impa t on boys. In addition, it affects not only the school comple-

tion r~tes of children but also the expenditure per child (Bankosta and E~en$on 1978).

Vulner bil,ty Finall , there is growing evidence that larger family size makes it difficult f, r poor families to get out of poverty and for the currently nonp or ~obe more prone to slide below the poverty threshold. Glewwe and H II !(1998), for instance, using panel data from Peru, find that famili s that have more children are more vulnerable to macroeconomic sh~cks. Vulnerability is defined as changes in the one's socioecono ic status, Using the 1997 FIES, and the 1998 and 1999 Annual Pover Indicator Survey (APIS), Reyes (200'2) shows very revealing pover dynamics. Tracing the movement of families in and out of poverty 0 er this three-year period, she finds that 46 percent of the families ar not affected and remain nonpoor throughout while 22 percent r main poor. Table 32 in her paper is quite revealing. It clearly shows thalt as one goes from being poor to being nonpoor, the family size d clipes. It clearly implies that getting out of poverty becomes harde wi,th larger family size.

Impli ations for policy Sever I themes can be gleaned from the foregoing discussions to guide policy namely: ne, while it would be wrong to attribute solely to high fertility the hi h incidence of poverty in the country, recent research provides even s ronger evidence showing the important roles that demographic chang s play in development in general, and poverty alleviation in particula .At the aggregate level, it retards the growth in per capita income it lowers savings rates and investments in physical and human capita. An even more overwhelming evidence of the depressing impact 0 high fertility, particularly on savings and human capital investments e~ists at the household level. The impact through the distribution c aQnel has also been found to be equally potent by recent researc ,showing that it skews the distribution of income against the poor. inally, household level studies continue to reveal the deleterious e ect of high fertility on the attainment of wellbeing of the poor given their incomes. These results should further strengthen the resolve f concerned sectors like the government to include, as part of the p verty alleviation package, programs to improve fertility management f poor couples.

Tw , while it has been argued that the observed pattern of the poor ba ing a larger family size is the result of their rational choice, a closer I ok at the data reveals that this can only be partially true in the case of t e Philippines. National survey data reveals that while wanted fertility th,e closest indicator of fertility preferences-of women from poorer ouseholds is higher compared to those from richer households, it alsp shows that the poor also have higher unwanted fertility.

The hig er unwanted fertility of the poor is explained by limited access to f mily planning and allied services, lower contraceptive prevalence ra es, and higher un met need for family planning. An effective family p anming program is thus needed to improve the poor's control over the rfertility and enable them to realize their fertility goals.

Th ee, current fertility choices not only have contemporary but also int generational impact. There is overwhelming evidence, even during t e ,1980s, when analysts doubted the importance of fertility regulati n in development, that high fertility leads to decreased investmen s in human capital. This has been identified as the main engine of i tergenerational transmission of poverty. It migh t too late to wait for hei poor to reduce their fertility to solve this problem. This requires prcl>activesubsidy and better targeting of public services to improve human capital investments (e.g., education and health) of the poo It lis worth noting that this has both short and long-term effects. In the short term, it shields the poor from deprivation due to their cu rent economic status. Over the long term, it helps stop the intergen rational transmission of poverty. These interventions have good so ioeconomic returns apart from dealing with the externalities of fertili decisions.

Fo r, it has been shown by decomposition analysis that in the Philippi es, growth is the primary contributor to the decline in poverty inci ence while crosscountry analysis considers the lowering inequality s playing a secondary role. Sustained economic growth should therefor remain the primary strategy of development in the immediate term with lowering inequality as the secondary strategy. On the role of d mographics, even those who believe in the important role it plays in evelopment are quick to add that these are mostly potential benefits. more conducive economic environment is required to translate thes into reality. This is clearly demonstrated by the difference in impact 0 similar demographic transitions unfolding in East Asian and Latin erican countries. In East Asia, the demographic transition

facilit ted rapid economic growth. In Latin America, on the other hand, a mo modest economic growth had been achieved. ive, globalization introduces at least two elements that have importa t implications, as enumerated by the foregoing discussions: 1) it cre tes opportunity, and 2) it means rapid changes in the economic envir nment. At the aggregate economy level, to benefit from opportuniti s created by globalization, the economy must be able to shift resou ces to sectors where demand is expanding from sectors where dema d is contracting. To the extent that high population growth deters i vestments in both physical and human capital, it means it can hinde these needed shifts. Similarly, at the household level, those who have ewer (and by all indications well endowed) children, will have bette chances of benefiting from globalization. This will clearly contribut to worsening inequality. Finally, recall that increases in family size i creases the vulnerability of households to changes in economic condi ions as well as to slippage into poverty. To the extent that globaliza ion implies more rapid changes in the economic environment, this eans increasing vulnerability for those who have large families. ix, all of the foregoing point to the important role demographic chang s play in development in general, and poverty in particular. They provi e more than enough justification for government to help couples achie e their desired fertility and promote small family size.
