Locally, the pattern of exurban growth continued, with St. Charles County adding 5,600 people between 2014 and 2015, more than any other Missouri county. The county now has an estimated 385,590 residents, up more than 25,000 since 2010, a rise of about 7 percent, and up nearly 100,000 people since the turn of the century.

St. Louis County’s population grew by an estimated 1,200 people last year, to a little more than 1 million.

Residents continued to trickle out of the city of St. Louis, though if recent estimates hold true until the next decennial Census, the city’s decline will have slowed to its lowest rate in the more than 60 years since population peaked in 1950. The city now has about 315,700 residents, according to Census figures.

A bright spot for both the city and the county was the number of immigrants moving in, though the overall migration flow for both was still negative.
