The net number of migrants to Arizona from elsewhere in the United States is highly cyclical, rising during economic expansions and falling during recessions. Though the highest figures were realized during the real estate boom in 2005 and 2006, on average across the economic cycle there has been no trend in the numbers since the early 1980s. The net migration rate—the number of net migrants per 1,000 state residents—has declined over this period. The net number of migrants to Arizona decreased substantially during 2007, 2008 and 2009, a result of the state’s long and deep economic recession. The 2010 figure was barely higher than in 2009 and was the third lowest in the 30 years of the time series.
