Questions over drop in Illegal population

The Arizona Republic reports:

Arizona has seen the sharpest decline in undocumented population of any state, losing 18 percent, or more than 100,000, of its illegal immigrants
in 2008, according to a new government report.

Experts agree that the decrease in Arizona's undocumented immigrant population was fueled by the staggering loss of jobs the state experienced during the recession, and that to lesser extent immigration crackdowns also contributed to the decline.
