U.S. Census Bureau figures released Tuesday estimate that Missouri's population grew by fewer than 20,000 people from 2014 to 2015, to a total of 6.08 million people.
That's a growth rate of about three-tenths of a percent -- well shy of the national rate of nearly eight-tenths of a percent.
Missouri's growth rate ranked 30th among states in 2015. But that was still good enough for Missouri to retain its position as the 18th most populated state -- a little ahead of Maryland.
Kansas has even slower growth. The new U.S. Census Bureau figures estimate that Kansas' total population grew by three-tenths of 1 percent from July 2014 to July 2015. The state gained about 9,100 residents to make its population almost 2.912 million.
The national growth rate was almost eight-tenths of 1 percent. Also, Colorado, Oklahoma, Nebraska, Iowa and Missouri all had higher growth rates than Kansas.
Colorado's growth rate of nearly 1.9 percent was the second-best in the nation, behind North Dakota's nearly 2.3 percent.
Kansas ranked 32nd among states and the District of Columbia in its growth rate. The Census Bureau also said Kansas saw a net loss from migration over the year of 2 residents per 1,000.
