The determination of the number of businesses operating in Arizona is not a straightforward proposition due to data deficiencies and definitional issues. The best data — from the U.S. Census Bureau — are more than two years old. The Census Bureau data are divided into two series: businesses with employees and nonemployer businesses. Each series is based on administrative records. While neither series is affected by sampling error, both are subject to nonsampling error. Certain industries are excluded from each series.

Arizona’s total value of international exports as a share of gross product was 33rd highest among the 50 states and District of Columbia in 2012. Arizona ranked 36th for manufactured goods. In 1997, Arizona had ranked eighth overall and ninth for manufactured goods. The state’s large relative decline in export share can be traced to its sizable relative decrease in its manufacturing sector. In particular, the electronics manufacturing subsector’s share of total GDP has dropped considerably.
