Also, the 21st century Missouri electorate is much less urbanized than that of the 20th century. In 1900, the combined population of St. Louis (575,238) and Kansas City (163,752) was 24% of the population of Missouri (3,106,665), while by 1950 the combined population of St. Louis (856,796) and Kansas City (456,622) had actually grown to 33% of the population of Missouri (3,954,653). But shortly thereafter the population of St. Louis began a sharp decline, while that of Kansas City remained nearly static, so that the state is now much more dominated by rural, suburban, and small-city voters, who are generally more conservative: by 2000 the combined populations of St. Louis (348,189) and Kansas City (441,545) had declined to 14% of the population of Missouri (5,595,211). This shift, however, is a direct product of the small geographic size of St. Louis City, which is nearly unique among major urban centers in having locked its boundaries in 1876. When the population of St. Louis County is included in these figures, Missouri's ratio of major metropolitan residents to rural residents closely matches the nation as a whole.
