Low population, low density, lots of farm land, can count the number of houses in a mile stretch of road on your fingers. May have one small commercial area within 15 miles with a dollar general, a gas station and, if you’re lucky, a grocery store. Not nearly enough businesses nearby to employ people even the measly number of people there that isn’t a farmer, so they commute to neighboring towns or counties to find work in factories, possibly dozens of miles away. I basically just described where my sister lives in Tennessee.
