23.1: That's the median age in Idaho's Madison County, home to BYU-Idaho, making it the nation's youngest, according to Census numbers released Thursday. Ranked after Madison in youth are Latah, home to the University of Idaho, and Elmore, home to Mountain Home Air Force Base, with median ages of 28.6 and 30.8, respectively.

52.7: The median age in Adams County, Idaho's oldest. Lemhi, at 52.2, and Boise, at 51.2, are the next oldest.

65.5: The median age in Sumter County, Fla., the nation's oldest, just west of Orlando.

37.6: The nation's median age.

35.5: Idaho's median age, which is inching up as the baby boomers age. That's an increase of nearly a year from 2010's 34.6.

35.8: Ada County's median age.

32.7: Canyon County's median age. Though it's no Madison County, Canyon is much younger than the state and neighboring Ada. (Median age means that half the population is younger and half is older.)

50.8: Percentage of the U.S. population that is female. Only 10 states have more males than females, Idaho being one of them. Utah, Wyoming, Montana and Nevada are among the others.
