[1]  [DOC] Kansas City is the largest city in Missouri, United States, and the sixth largest city in the Midwest. According to the U.S. Census Bureau, the city had an estimated population of 481,420 in 2016, making it the 37th largest city by population in the United States. It is the anchor city of the Kansas City metropolitan area, which straddles the Kansas–Missouri border. Kansas City was founded in the 1830s as a Missouri River port at its confluence with the Kansas River coming in from the west. On June 1, 1850 the town of Kansas was incorporated; shortly after came the establishment of the Kansas Territory. Confusion between the two ensued and the name Kansas City was assigned to distinguish them soon thereafter. [END]
