Population, Percent Change
Percentage population growth in Arizona typically ranges from twice as fast as the national average during recessions to three times as fast in other years. However, the estimates for 2009 through 2011 show growth in Arizona only a little greater than the U.S. average. Since 2011, the population has increased at a faster pace in Arizona while the U.S. average has not changed.
Since the estimates for Arizona do not reflect the impacts of the “employer sanctions law” that went into effect at the beginning of 2008, the estimated changes for 2008 and the next few years likely were too high and the changes for the 2001-through-2007 period likely understate slightly the actual population changes.
Note on missing data for all trended county data: La Paz County was created in 1982, as the then-existing Yuma County was split into La Paz County and a smaller Yuma County.
