This is the final national level population projection for 2020. population for 2020 is set to the sum of the state populations. Using 2017 as the launch year, we apply this exponential growth rate to get the final state level projections for 2020. The exponential growth rate for each of the 50 states and D.C., is calculated using population totals from 20. TOTAL POPULATION PROJECTIONS 2020 Total Population 2017 (1 July estimate by Census Bureau) – total.2010 (1 April count) – by 18 age cohorts, divided into male, female, and total.2000 (1 April count) – by 18 age cohorts.1990 (1 April count) – by 18 age cohorts.State population projections are controlled to the national total age is controlled to the state total population and sex is controlled to each age-group. Detailed national characteristics are equal to the sum of the projections for each of the 50 states and D.C. We use the Hamilton-Perry approach, which is a reduced form of the cohort-component method. The projections include total population, by five-year age groups, and by gender State and National Projections Methodologyīelow are the steps we followed when developing projections for the nation, the 50 states, and the District of Columbia for 2020, 2030, and 2040. The excel document contains several worksheets please click on the tabs at the bottom of the document to view the 2020, 2030, and 2040 projections as well as percent population 65+ and median age. The following Excel files contain aggregate population data for each state and the nation. Retrieved from National Population Projections Data The Center’s 2018 projections for 2020 are highly accurate compared to the 2020 actual Census count, and the Census Bureau frequently refers data inquiries to the Cooper Center website.Ĭitation: University of Virginia Weldon Cooper Center. Census Bureau, detail changes between 20 in overall population and in subgroups by age and sex.Ĭooper Center projections have an outstanding reputation and are widely used by many states and federal agencies, including the Congressional Budget Office. The projections, which were produced using the most recent population estimates and census data from the U.S. These population projections for the nation overall, and for all 50 states (and the District of Columbia), were produced and released by the Cooper Center in December 2018. A new round of national and 50-state population projections for 2030-2050, benchmarked on the 2020 Census, will be available by Spring 2024.
