Kansas Kansas, Missouri rank among slowest-growing U.S. states, 2020 Census data shows Published 4 years ago on April 26, 2021 By Matt Collins Editor Share Tweet KANSAS – Although the results of Monday’s first 2020 Census results, called apportionment, are intriguing to the political class, the news for the 37 states not directly affected is in the underlying numbers. Missouri, which lost one seat in the U.S. House of Representatives after the 2010 Census, continues to see its population grow — just not particularly quickly. According to the new 2020 Census data, the Show Me State’s resident population hit 6.15 million, a 2.77% increase from 2010. Kansas, which last lost a seat in the U.S. House after the 1990 Census, also was among 47 states to see its population increase during the past decade. The Sunflower State’s resident population increased 2.97% to 2.94 million. Only Illinois (-0.1%), Mississippi (-0.2%) and West Virginia (-3.2%) saw populations fall since the 2010 Census. Despite seeing their populations increase, both Missouri and Kansas trailed the nation’s average population increase (7.35%) by a wide margin. Here’s a look at how Kansas and Missouri compare with the rest of the nation in terms of population increase by percentage and numerically: Missouri fell one spot to 19th among the nation’s largest states, swapping places with Maryland (now 18th). It ranked as the 39th fastest-growing state (2.77%) from 2010 to 2020. Kansas dropped two spots and became the 35th largest state. It was surpassed by Utah — the nation’s fastest-growing state at 18.37% larger than in 2010 — and Nevada — the nation’s fifth fastest-growing state, with a 14.96% increase in population. Kansas ranked as the 37th fastest-growing state (2.97%).
