Community Profiles: 2015-2019 American Community Survey & 2010 Census
Profiles created and data compiled by CNHRPC
U.S. Census Bureau Data Available:
- The Decennial Census has been conducted in years ending in “0” since 1970, as required by the U.S. Constitution. The Census counts the population in all 50 states, the District of Columbia, and five U.S. territories. This information helps allocate federal funding for communities and services such as hospitals, fire departments, schools, roads, etc. , determines the number of seats each state will have in the U.S. House of Representatives, and are used to draw congressional and state legislative districts.
- The American Community Survey (ACS) 1-year estimates are released annually for areas with a population of 65,000 or more. These are not decennial census results; they are based on survey data collected in a calendar year. These data describe the social, economic and housing characteristics of the population.
- The American Community Survey 5-Year Data is an ongoing survey that provides data every year. The 5-year estimates are “period” estimates that represent data collected over a period of time. These are not decennial census results; they are based on survey data collected over five calendar years.
- The primary advantage of using multiyear estimates is the increased statistical reliability of the data for less populated areas and small population subgroups. Estimates are available for the smallest geographic areas as geographies do not have to meet a particular population threshold in order to be published.
