The Federation for American Immigration Reform (FAIR) has outdone itself when it comes to shoddy research.

In a recently released report on “demographic changes” in Arizona, FAIR utilizes an almost random assortment of statistics to make its case that the state’s unauthorized immigrants are fleeing in droves thanks to get-tough immigration policies. The report occasionally pays lip service to the impact on unauthorized immigration of the 2008-2009 recession, as well as persistently high unemployment rates that continue to this day. Yet FAIR concludes, without evidence, that state-level immigration enforcement has been the single most important factor causing the decline of the unauthorized population. In reality, this conclusion is not supported by the data which FAIR presents.
