I’m looking at the 2014 ACS, and there are a bunch of records that have the METRO variable indicating that metropolitan status is not identifiable, but then have an actual metro area assigned to them. What’s going on with these?
Never mind; turns out this is covered in the MET2013 description section as a result of mismatch between PUMAs and 2013 MSAs: https://usa.ipums.org/usa-action/vari…
