DEMOGRAPHICS Studying demographics helps uncover possible health disparities often attributed to social, economic, and/or environmental disadvantage. According to Healthy People 2020, “health disparities adversely affect groups of people who have systematically experienced greater obstacles to health based on their racial or ethnic group; religion; socioeconomic status; gender; age; mental health; cognitive, sensory, or physical disability; sexual orientation or gender identity; geographic location; or other characteristics historically linked to discrimination or exclusion.” To reiterate, Orange County is CHOC Children’s PSA. California’s total population is 39,813,541 people of which 22.9%, or 9,125,894, are children aged 0-18 years old.2 Orange County has 8% of California’s total population but 0.5% of its land area. Orange County is the third largest county in California by population size with 3,252,459 residents in 2019. The median age is 37.9 years old.3 Children (0-18 years old) make up 22.1%, or 719,221 children,4 of the Orange County population. Orange County’s age cohort 0-18 is projected to decrease nearly 1% by 2024.
POPULATION CHANGE The shifting population trend is important to assess for potential impacts on healthcare providers, healthcare access and utilization of community resources. While the natural population increase (births minus deaths) has outpaced migration as the county’s principle source of growth, international immigration—largely from Asia and Latin America—has contributed significantly to Orange County’s growth over the past 30 years. Between 2019 and 2024, it is estimated that Orange County will have a 3.6% total population increase.5 Orange County Growth by Age Cohort, 2019-2024 Orange County Population Cohort
