Arizona adds nearly 100,000 residents in 2015

Arizona added nearly 100,000 residents over the past year, sluggish gains by the state's historic standards, but enough to remain among the fastest-growing states in the nation.

The latest population estimates from the U.S. Census Bureau show Arizona is the 14th-most-populous state after passing Massachusetts in 2015. Arizona grew 1.5 percent and had 6,828,065 residents as of July 1, the agency estimates.
