More than 6 million illegal-immigrant Mexicans now live in the United States, making up more than half of the nation's nearly 11 million illegal aliens, a new study finds. The report, by the Pew Hispanic Center, found that illegal immigrants have dispersed far more widely than 15 years ago, with nearly 40 percent now living outside of the six states that traditionally have attracted the most immigrants. Arizona is now fifth on the list, vaulting ahead of Illinois and New Jersey and trailing only California, Texas, Florida and New York.
