Is Kansas City in Missouri or Kansas?

There are cities with the same name in both Missouri and Kansas, and are just across the Missouri River from each other. Kansas City's metropolitan area has the distinction of being one of only three American cities (the others are St. Louis and New York) that have area in two states. However, the Kansas city is governed as part of Wyandotte County, Kansas, not as part of the larger city.

The Missouri state border is along the meandering Missouri River that flows through Kansas City, and the river separates the less-populated Kansas side from the Missouri side.
