I would like to see data for businesses--type of business and number of people employed by tract in the 2019 ACS. Is there such a table?
ACS is a household survey. Census does have business data products, but for reasons of confidentiality protection, you don't even get detailed data at the county level -- that is, publicly available. If you are a faculty at a university that has an affiliated Census Research Data Center, then you may try your luck with getting the data through these.
Do you happen to know what happened to the Atlanta CRDC? I'm getting this: Not Found - Andrew Young School of Policy Studies (gsu.edu)
