Hey all,
Thank you all for your help!!!
The excel file (list of geographic restrictions by table) at the following location lists the geographic level of availability.
www.census.gov/.../data-suppression.html
1. Census does not produce some tables at the block group level for certain population characteristics deemed sensitive. Disability has been listed as a sensitive topic since the first 5-year disability tables in 2012.
2. I think at one point there was a spreadsheet that listed the smallest geography available for each table, but I cannot find it anymore.
3. The PUMS data dictionary can help explain the variables (2015-2019 ACS PUMS Data Dictionary (census.gov)). The six disability types are not mutually exclusive; respondents can identify with more than one type of disability.
