14. Wisconsin
Illegal immigrants per 10,000 people: 1,229
Most of the illegal immigrants in Wisconsin, up to three-quarters, are from Mexico, which is unsurprising considering Mexicans make up more than half of all illegal immigrants in America. Laying credence to my statement that most illegal immigrants have been in the country for many years, 81% of those in Wisconsin have been present in the country for over 5 years.
