American Community Survey (ACS) 5-Year estimates  

Started in 2010, the Census Bureau releases 5-year averages estimates for all geographic areas, regardless of population size. These estimates are based on data collected over a 5-year period of time and therefore they describe the average characteristics for that 5-year time period. The geographic areas in 5-year averages estimates are available for every state, county, city, town, place, American Indian Area, Alaska Native Area, and Hawaiian Home Land, as well as for census tracts and block groups. The five-year estimates from the ACS replace estimates from the decennial census long form started in 2010.

 

5-Year ACS estimates can be also accessed via the Census Bureau's American FactFinder web application. However, detailed ACS tables for block groups are not published in American FactFinder, they are only included in the Summary File product. Our center provides 5-Year ACS Summary File (also known as Detailed Tables) including block groups level data in SAS, SPSS & STATA formats. There are two types of data post on our website: the estimates data and the margins-of-error data in separate files. A file like “e20095wa_BlockGroup_King.sas7bdat” indicates all the tables of estimates data at block group level for King County. Please read the “READ ME” document for instruction, e.g., how to extract variables from a complete data file.

 

Obtaining ACS-SF data by variables (in SAS format) is also available on the Missouri Census Data Center website for the nation and some of states.

 

Census Bureau provides Summary File Retrieval Tool   [XLS 4.64MB] - an Excel Macro tool ideal for downloading 20 tables or less for all published geographies within a state.
