ACS 19-23 Group Quarters Population at the block group level

  • 1.  ACS 19-23 Group Quarters Population at the block group level

    Posted 01-15-2025 10:52 AM

    Hi everyone,

    I am looking for population in group quarters estimates from ACS 2019-23 (specifically variable B26001_001) but this data doesn't seem to be available at the block group level (unlike for previous years), and I need it at the block group level for my custom aggregations.

    I'm wondering if it is okay to calculate the group quarter population using: total population - population in households?

    In other words, is everyone classified as either living in a household or in group quarters?

    Thank you for your help!

    Roshni, yes, in census and ACS data, everyone is "classified as either living in a household or in group quarters," so you can calculate group-quarters population by subtracting population in households from total population.

    I found that the 2019-23 ACS tables still provide give counts of population in households for block groups in B11002, B28005, B28008, and B28012... maybe others.
