The Census Bureau’s Population Estimates Program (PEP) produces estimates of the population for the United States, its states, counties, cities, and towns, as well as for the Commonwealth of Puerto Rico and its municipios. Demographic components of population change (births, deaths, and migration) are produced at the national, state, and county levels of geography. Additionally, housing unit estimates are produced for the nation, states, and counties.
PEP annually utilizes current data on births, deaths, and migration to calculate population change since the most recent decennial census and produce a time series of estimates of population, demographic components of change, and housing units. The annual time series of estimates begins with the most recent decennial census data and extends to the vintage year.
The 15 community types identified in the American Communities Project (ACP) were derived from a standard clustering method of analysis, conducted by political scientist Iris Hui, PhD, where a set of 36 different indicators – everything from population density to military service members – were sorted using an algorithm that identified like places.
The majority of the data used to define the types in the ACP came from the U.S. Census American Community Survey, 2008-2012. Data on religious adherence and faith came from the Religious Congregations and Membership Study, 2010.
