Missouri’s population continues to grow at a slower rate than the rest of the country. New estimates from the U.S. Census Bureau show Missouri’s population of 6 million grew by fewer than 20,000 people from in the past year. That’s a growth rate of about one-third of a percent. In the rest of America, the population rose slightly more than that. Missouri’s growth of 0.3 percent was typical for the Midwest. It was better than Illinois, about the same as Arkansas, Kansas and Kentucky, but lagged behind the rest of its neighboring states. Missouri’s population growth rate ranked 35th nationally.
