For American Community Survey (ACS) tables listing place of birth, how do I find out which countries are included in groupings such as "Northern Europe?"

The ACS Code Lists contain information on how countries are grouped in the "Place of Birth, Migration, & Place of Work Code List" section. The list also shows detailed codes for other variables with numerous coded responses.

You can also visit the Comparing ACS Data page for more information on comparing place of birth data between the ACS and 2020 Census or between various years of the ACS.
