AMERICAN FactFinder – Starting in July, data.census.gov will be the primary way to access Census Bureau data, including upcoming releases from the 2018 American Community Survey, 2017 Economic Census, 2020 Census and more. After July 1, 2019, all new data (previously released on American FactFinder) will be released on this new data platform.
American FactFinder (AFF) will remain as an “archive” system for accessing historical data until spring 2020.
