For years, Mount Pleasant has worn “one of the fastest-growing cities in America” like a badge — sometimes proudly, sometimes through gritted teeth in traffic on the 17.
So this one lands a little strange. New Census Bureau estimates say Mount Pleasant lost population in the 12 months ending July 2025 — a drop of more than 500 people, roughly half a percent. The Post and Courier called it an unprecedented drop. For a town that’s been a growth poster child for well over a decade, that’s a record nobody was chasing.
The town isn’t buying it.
And to be fair, municipal leaders almost always dispute census estimates, especially when something’s at stake. Charleston disputes its number too — the Census Bureau credited the city with gaining just 632 residents, while Charleston’s own planning director says the real figure is north of 165,000 and climbing, based on building permits. So take the specific numbers with a grain of Lowcountry salt. But the trend underneath them is real, and it’s the actual story.
Growth is leapfrogging the big cities.
South Carolina is still growing faster than any state in the country. But the surge has moved. The five largest cities grew about 1 percent last year. The five fastest-growing municipalities — towns a tenth their size — grew 12.2 percent. Woodruff gained more residents than Charleston. Greer outgrew Columbia. Near us, Moncks Corner posted double-digit growth again, ballooning from 13,311 residents in 2020 to more than 20,600 — and the town now charges impact fees of nearly $4,805 on every new house to help pay for it. The why is familiar: housing costs. “As housing prices rise, people look to smaller cities that are less expensive,” USC economist Joseph Von Nessen said in the Post and Courier.
What it means for here.
A pause in Mount Pleasant’s population growth — if that’s what this actually is — isn’t automatically bad news. This is a town that’s spent years debating whether it can build roads and schools fast enough to keep up. A breather has its upsides. But it also tells you something about price. When a place gets expensive enough, growth doesn’t stop — it just moves up the highway to Moncks Corner, Goose Creek, and the unincorporated stretches of Berkeley and Dorchester counties. Mount Pleasant may have just gotten its first real taste of what the other side of the boom feels like.
