Among states, women's median weekly earnings last year ranged from a low of $564 in Montana to $878 in Connecticut. Women on the East Coast enjoyed some of the highest earnings; in Massachusetts, New Jersey and Maryland, women's weekly earnings were more than $800.

Earnings differ across the nation due to variations in occupation, industry and age composition of each state's labor force, according to the bureau.
