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.

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.
