Yeah, lot's of illegal criminal Mexican wetback aliens running around Pennsylvania stealing jobs from the Amish. Go buy a map!
The INS estimated in February 2003 that the illegal alien population in Pennsylvania was 49,000 as of January 2000. That represented an increase of 12,000 illegal aliens from the previous INS estimate that as of October 1996 there were 37,000 illegal residents. The latter estimate was a 37 percent increase above the INS estimate for 1992 (27,000).
Only 19 states have larger numbers of illegal resident aliens than Pennsylvania, according to the current INS estimate
