Cambridge Statistics Elsewhere on the Web
Census Bureau and American Factfinder
The American Factfinder website, maintained by the United States Census Bureau, is the primary source for distributing to the public various population, housing, economic, and geographic data sources. Data from the 2010 U. S. Census and all iterations of the American Community Survey is available through American Factfinder. Other data sets available include results from the 1990 Census, 2000 Census, 2007 Economic Census, and current population estimates among others. Data is available at the city, zip code and census tract level, depending on the data set you chose to review.
There are three Census Bureau data products that provide population related data:
Often referred to as simply "The Census", the decennial census is mandated by the U. S. constitution to occur every ten years and serves as the basis for apportionment of legislative seats. Every resident of the United States is required to respond to basic questions about sex, age, race, Hispanic origin, family and household relationship, and housing tenure. Data from the decennial census is sometimes referred to as 100% data, since it includes responses from the entire population.
In response to concerns about currency of data and cost, the Census Bureau replaced the socioeconomic information from the decennial census long form questionnaire with the results of the American Community Survey (ACS). The ACS is a sample based survey that determines the distribution of characteristics in a population. The ACS is not designed as a measure of population size. ACS results are reported both as quantities and percentages. Quantities are based on the Census Bureau's current population estimate program.
Population Estimates Program
The Population Estimates program of the Census Bureau fulfills the need for population counts between the decennial censuses. These estimates are used in federal funding allocations, as survey controls, as denominators for vital rates and per capita time series, and as indicators of recent demographic changes. With each new release of annual estimates, the entire time series of estimates is revised for all years back to the last census. All previously published estimates are superseded and archived.
