I have some code (below) which runs fine for getting census block group data for a certain geo (Atlanta as example below) for ACS surveys 2013/14/15/16/17. however when I run it for 2012 or prior i get the following error.

Getting data from the 2008-2012 5-year ACS Error: Your API call has errors. The API message returned is error: unknown/unsupported geography heirarchy.

  • This is an issue with the new Census API not currently accepting wildcards for block groups for certain years. We are unable to retrieve all block groups in a county from the API without iterating through each tract. Hopefully this functionality will be rolled back into the new API. See these issues in the tidycensus repo for more details: https://github.com/walkerke/tidycensus/issues/173 and https://github.com/walkerke/tidycensus/issues/193 – mfherman Oct 01 '19 at 13:16
