Missouri’s population grew by about 137,500 or 2.3%, between 2010 and 2018 according to new population estimates released by the Missouri Census Data Center in June. As of July 2018, the state’s population stood at just more than 6.1 million, according to the estimates.
That population growth from 2010 to 2018 was not evenly distributed across all parts of the state. The highest-growing counties were Platte (15.3%), Christian (12.4%) and Clay (11%). Counties that lost the most population were Pemiscot (-11.1%), Holt (-10.3%) and Atchison (-9%).
Annual statewide population change was relatively steady over the period, hovering between a low of 0.23% in 2010-11 and a high of 0.35% in 2016-17.
