Monowi, Nebraska. Population: 1
“When Eiler’s husband, Rudy, passed away in 2004, he didn’t just leave her to run the tavern, but the whole town. Today, according to the US Census, Monowi is the only incorporated place in the US with just one resident, and Eiler is the mayor, clerk, treasurer, librarian, bartender and the only person left in the US' tiniest town.” www.bbc.com/travel/ga…
