The Federation for American Immigration Reform (FAIR), in a Mar. 2007 website article entitled "Illegal Aliens and Crime Incidence," offered the following:

“Most Americans equate illegal aliens with a higher incidence of crime… in fact, data show that the American public understands the facts better than the academics. Adult illegal aliens represented 3.1 percent of the total adult population of the country in 2003. By comparison, the illegal alien prison population represented a bit more than 4.54 percent of the overall prison population. Therefore, deportable criminal aliens were more than half again as likely to be incarcerated as their share of the population.”
