According to estimates released by the U.S. Census, three local cities are among 10 in Illinois and Missouri that gained the most people between 2015 and 2016. The  numbers are estimates of the population for cities and towns across the United States.  

Wentzville, in St. Charles County, grew by more than 1,800 people, second only to Kansas City. O'Fallon, Missouri was 4th on the list, gaining about 1,400, and Clayton, in St. Louis County came in 8th, with an increase of around 750.

On the shrinking end, the city of St. Louis lost nearly 3,500, only behind Chicago. There were no other local cities in the bottom 10.

Here are a few more takeaways from the new Census numbers:

Five Missouri cities gained more than 1,000 people, while none in Illinois did.

Kansas City, Wentzville, Columbia, O'Fallon and Lee's Summit each added more than 1,000 people to their populations. Champaign, Illinois, home of the University of Illinois at Urbana-Champaign, almost joined the group, adding 995.

Chicago and St. Louis were the only cities to have lost more than 1,000 people.
