According to the 2000 Census figures, Missouri's population is more diverse than ever, especially urban areas. Missouri's American Indian and Alaska Native race category experienced the second largest percent increase for Missouri minority populations, 24%, growing from 20,221 in 1990 to 25,076 in 2000. Missouri's total population grew by 9.3% from just over 5.1 million in 1990 to slightly under 5.6 million in 2000.
Jackson County, St. Louis County, and Green County led Missouri in American Indian and Alaska Native populations with 3,168, 1,717, and 1,583 persons respectively. Scotland, Putnam, and Knox counties reported Missouri's smallest American Indian and Alaska Native population with populations of 7, 5, and 1 respectively. Green County reported the largest increase in population with a growth of 290 persons, a 22.4% increase since 1990. Worth County reported the largest percent increase, 700%, growing from a population of 1 in 1990 to 8 in 2000. Overall, 21 Missouri counties experienced a percent increase since 1990 of 100% or higher
Not all of Missouri counties experienced positive growth in the Native and Alaskan Indian populations. Jasper County reported the largest decline, losing 127, in Native and Alaskan Indian persons. Ray County and St. Louis City reported losses of 29 and 21 persons respectively. Knox, Putnam and Gentry counties reported the largest percentage decrease in Native and Alaskan populations with 90%, 44.4%, and 40% respectively. Overall 21 Missouri counties reported negative growth, while only Marion County reported no change in populations.
Census data for the 1990 and 2000 census are not directly comparable because individuals could report only one race in the 1990 census and could report multiple races in 2000. Thus the difference in population is due to both the changes in Census questionnaire and to real population change.
