U.S. Counties with Youngest Populations Driven by Universities, Military, and Cultural Factors
While the national median age in the U.S. is at a record high of 39.4, several counties across the country are bucking this trend, maintaining significantly younger populations. These youthful demographics are primarily influenced by the presence of major universities, military bases, and specific cultural or ethnic compositions. For instance, Madison County, Idaho, home to Brigham Young University-Idaho, consistently ranks as the youngest county with a median age of 21.4 years. Similarly, Utah County, Utah, with Brigham Young University and Utah Valley University, has a median age of 26.5. Military installations also contribute, as seen in Pulaski County, Missouri (Fort Leonard Wood), and Chattahoochee County, Georgia (Fort Benning), which have median ages of 27.8 and 24.4 respectively. Additionally, counties with higher percentages of Hispanic residents, like Brazos County, Texas, and Webb County, Texas, also exhibit younger populations and higher birth rates.
