Survey: Half of Mexicans want to come here

That's the headline grabber.The Pew study has this interesting information:

According to the Population Council, 400,000 Mexicans, or less than 0.4 percent of the population, migrate to the United States every year. About 75 percent of these people enter the United States illegally, the council says. In July, the CIA estimated Mexico's population at 106 million.
