I found this in commentary on a site. I have not had a chance to confirm this data, but I think it is enough to start a conversation.

And Arizona is helping the Sanctuary State of California. Since SB1070 and employer sanctions over 200,000 illegals have left Arizona and I am sure many have decided to move to California to fill up their schools, court system, jails, prisons, hospitals and welfare offices. VIVA SB1070. Mesa a suburb of Phoenix, lost over 7,200 students and had to close 3 schools. Phoenix is also closing schools, car jacking, kidnappings, home invasions, auto theft has all dropped dramatically. The Maricopa County jail in Phoenix had its daily jail population drop by 2,000 inmates.
