Data on undocumented immigrants

Dear IPUMS staff,

I would like to know if IPUMS-ACS has information about undocumented inmigrants. I can not see this in the Citizenship variable.

Thanks for your help

The CITIZEN variable only identifies citizenship status and does not indicate undocumented status. It is not possible to directly identify undocumented people in IPUMS USA data. Some third party organizations, however, have undertaken this effort. One of these is the Center for Migration Studies, although I do not think they make their microdata publicly available.
