The town of Humeston, Iowa, straddles Highway 65 in the northwestern corner of Wayne County, less than a 30-minute drive from the Missouri border. Its population peaked in the 1920s at 1,214 people. Today, the southern Iowa town has only 494 people. “A lot of kids, when they graduate, they want to get out and see the world,” David Dotts, of the Wayne County Board of Supervisors, said. It’s one of the many explanations for the population loss.
