I am using the 1-year ACS microdata to create cross tabulations at the METAREA level. Some variables however do not allow cross tabulation with the METAREA. For example, FOODSTMP and CIHISPEED won’t cross tabulate with the METAREA after 2011 and for all years at all, respectively.
If you go to the Census.gov however, you will see these variables made available at the METAREA level. I understand PUMA is the smallest geographical unit for the mentioned two variable in the microdata, but since they are tabulated at the METAREA via Census.gov, I am not clear on what’s happening in the microdata. Is this because the Census decided to withhold the county level data for FOODSTMP and CIHISPEED from 2012 onward?
Any insight would be really appreciated.
