American Community Survey (ACS) Data (view source)

, 15:17, 11 February 2021→Using api.census.gov
=Using api.census.gov=
The new approach is to use api.census.gov to request information. Each year has an API urlURL, which specifies the dataset and that takes '''get''' and '''for''' name-value pairs that specify variables and geographies, respectively. Generally, one can request geography, variable, and examples HTML pages on the same URL (rather than specifying the params). The ACS5 data goes back to 2009 and the ACS1 goes back to 2005 using the base URL: '''https://api.census.gov/data/yyyy/acs/acsx/''', where yyyy is year and x is 1 or 5.
For , example, for 2019, the URLs are:
*The 2019 ACS5 available geographies: https://api.census.gov/data/2019/acs/acs5/geography.html
*The 2019 ACS5 available variables: https://api.census.gov/data/2019/acs/acs5/variables.html
*Some example URLs for the API: https://api.census.gov/data/2019/acs/acs5/examples.html
*An example request: https://api.census.gov/data/2019/acs/acs5?get=NAME,B06011_001E&for=zip%20code%20tabulation%20area:
Example API calls for median income, educational attainment, and race from the 5yr ACS, using the 2019 dataset:
