U.S. Population Estimates

The Population Estimates Program (PEP) at the U.S. Census Bureau produces yearly estimates after each published decennial census (the last one being in 2000). Existing data on births, deaths, Federal tax returns, medicare enrollment, and immigration, are used to update the decennial census base counts.

PEP prepares estimates of the population by age, sex, race, and Hispanic origin for the nation, states and counties. It also prepares estimates of the total population of functioning governmental units, and estimates of the number of housing units for states and counties. The estimates developed from this program are used for a variety of purposes including the annual allocation of over $200 billion in federal funds, as denominators for statistical indicators, and the basis for program planning and development. 

Offers current year estimates and 5-year projections up to the year 2010. With these population estimates, you can study current and future demographic and housing trends. The GeoLytics Planner's Package also includes detailed statistics based on censuses conducted in 1980, 1990, and 2000. Notably, the Planner's Package enables you to analyze and compare statistics within a variety of geographical boundaries. For instance, you can conduct in-depth studies involving state-to-state, city-to-city, zip code-to-zip code, or census tract-to-census tract comparisons. You can also create reports and thematic maps using any combination of geographies.
