You might want to rethink that last statement, there are some outliers in both:
State........% Illegals.... AA/Hisp/White Unemp%
Cali..............6.0................11.0/7.2/4.4
Nevada........7.2................13.5/7.9/5.0
NY................3.9..................8.2/5.6/3.8
Mass............3.1................10.6/11.9/3.5
Conn............3.4................13.2/nd/3.5
Texas...........6.1..................7.5/5.1/3.6
Tenn............1.9..................7.5/nd/4.8
FL................4.2..................9.0/5.5/4.0
Miss............0.8...................9.4/nd/4.1
AL...............1.3..................10.3/nd/4.1
To the casual eye it would look like the white unemployment rate is always under 5% regardless of where you go. And with the exception of Mass black unemployment is always higher than hispanic unemployment.
