Sioux Falls is the most optimistic city in the United States, according to Gallup.

The sunny optimism of South Dakota’s largest city just edged out the almost as sunny optimism of Des Moines, Iowa, 77.7 percent to 76.6 percent.

Gallup asked respondents if they believed the city they lived in was getting better.

Sioux Falls and Des Moines might want to share some of their glass half full positive thinking with Binghamton, N.Y., where only 36.5 percent of the residents feel their city is getting better.
