Median age very dramatically even between rural counties. Many counties in the rural southwest have a median age less than 37, probably due to a large number of immigrants [1]. For example, much of California - rural or urban - is very young (Even if the wealth is concentrated in the hands of older people). It's the same for Western Texas. So their fate with respect to population decline is probably different than rural parts of Central Illinois or rural parts of the East and Midwest. 1. https://www.census.gov/library/visualizations/interactive/2014-2018-median-age-by-county.html https://www.census.gov/library/visualizations/interactive/20...
