What is the only incorporated municipality in the US with a population of one person according to the 2010 census?

Monowi is an incorporated village (total area 0.21 sq. mi.) in Boyd County, Nebraska, US. According to the 2010 census, it has a population of just one person, the only incorporated municipality in the United States with such a population. Monowi was platted in 1902 when the Fremont, Elkhorn and Missouri Valley Railroad was extended to that point. Monowi's peak years were in the 1930s, when it had a population of 150. Like many small communities in the Great Plains, it lost its younger residents to the cities. During the 2000 census, the village had a total population of 2; only one married couple lived there. The husband died and his wife (Elsie Eiler) remained. In this capacity, she acts as Mayor, granting herself a liquor license (she runs a tavern and maintains the library there) and paying taxes to herself. She is required to produce a municipal road plan every year in order to secure state funding for the village's four street lights.
