In a rapidly urbanizing world, where more than two in three people are expected
to live in cities by 2050, internal migration is often feared as a source of urban
underdevelopment. Over the coming decades, urbanization will be especially
fast in Asia and Africa, where the urban share of the population is still
substantially lower than in other regions. Historically, internal migration has
been an important driver of urbanization. However, migrants are commonly
perceived to have more difficulties integrating into the urban labor market than
urban nonmigrants, given their lack of education, social networks, and family
support in towns and cities. As a result, they are thought to mainly join the
ranks of the unemployed and underemployed in the urban informal sector,
and, if they do work, to take scarce jobs from citizens.
