Where can I get block group level estimates for the American Community Survey (ACS)?
Block group level estimates are available in the American Community Survey (ACS) Summary File 5-year datasets. Learn more about the ACS Summary File on the ACS website. You can also watch our new video about accessing block group data with the ACS Summary File Retrieval Tool. This level of geography is not available in the ACS 1-year or 3-year datasets. Block groups are also not available in American FactFinder.
