It did grow by about 2,000 people between 2010 and 2020, but we’re still talking about a county of 35,000 total.
In terms of development, the entire metro area is riddled with floodplains, but the Missouri side with the far greater population is the side of the river that decided to start building on them over the last three to four decades en masse. That came back to bite them in 2019 when the region suffered large scale flooding.
The Illinois side has plenty of floodplains of its own, but there’s far less incentive to build. People aren’t exactly trying to live in or around East St. Louis, the industrial park that is Sauget and, or Centreville (now consolidated into Cahokia Heights) that’s made the national news multiple times for its sewers backing up into people’s homes anytime the region gets rain. Most of the Illinois development since ESTL’s downfall has been further east, on top of the hills and bluffs further from the Mississippi. Or at least that’s the story of St. Clair County. Madison County hasn’t been much different, but there’s nothing like the demise of East St. Louis over there. Granite City and Alton certainly saw their populations fall, but nowhere near the same extent as ESTL. Both cities still have their desirable areas.
