ACS Subjects not available for block groups?

if you look at the summary file documentation - the Appendices excel file found here
www.census.gov/.../summary-file-documentation.html

You will see the tables listed along with geography restrictions. Those that are not available by blockgroup have "No Blockgroups" listed as the geography restriction.

And yes, I believe the reason some are not available by block group would be due to too small of a sample size.

Thanks JamiRae and Bernie , very helpful. I was able to get (most of) the estimates I wanted through other tables. For example, there was no direct count of persons with disability for some reason, but there was Table B21007 "Age by Veteran Status by Poverty Status in the Past 12 Months by Disability Status for the Civilian Population 18 Years and Over" which you can sum to get the number of persons with a disability.

This is kind of hacky, and makes me wonder why? If sample size was the issue, having a much more specific count available like B21007 but not the broader "Persons with a disability" set doesn't make much sense. You would think only populations with the broadest pools would be counted for block groups.
