There are more women than men in some of the largest urban U.S. counties east of the Mississippi River, on the Eastern Seaboard and in the Deep South.

The biggest imbalances of men to women, with ratios above 103 for those age 18 and over, were recorded in the West, in counties that are home to Colorado Springs, Colo.; and Austin, as well as California counties that are home to San Francisco, San Jose and Bakersfield, where agriculture and energy are two of the biggest industries.
