“Prince William County’s controversial immigration policy appears to have had some effect, as the growth of the county’s Hispanic population now lags behind that of other jurisdictions, a report from the University of Virginia states,” the Washington Post reports. ”The three-year, $385,000 study - released Tuesday by the university’s Center for Survey Research - also found that the county’s noncitizen Hispanic population, legal and illegal, dropped by 7,700 from 2006 to 2008, and that illegal immigrants accounted for 2,000 to 6,000 of that decline.”
