About this ranking
Female residents as a percentage of total population on 1 July. United States: Census Bureau county population estimates by sex; states and the nation are sums of their counties.
Counties with large prisons or military bases can have low shares.
Every value in the ranking comes from the same publisher and the same period, so the counties are compared on one definition. 9 counties with data in other periods have no value for 2018 and are left out rather than filled from another source. Equal values share a rank.
