The Charleston-North Charleston metro added more than 70,000 residents between 2020 and 2024, nearly nine percent growth while the country grew about three, and the regional development alliance projects one million people by 2032. Mount Pleasant went from 67,843 residents in 2010 to 90,801 in 2020 and is now the fourth-most populous municipality in South Carolina. Summerville, mostly in Dorchester County, keeps filling in around its I-26 exits at Nexton Parkway and Jedburg Road. Every one of those households is shopping for a pest contract, an HVAC company and a painter at once.
Big employers keep that demand steady. Joint Base Charleston serves over 90,000 personnel from every branch and reports nearly $11 billion a year in economic impact, and Boeing builds and flight-tests 787s beside the airport in North Charleston. Tourism alone supported a record 55,500 jobs in 2025. Getting around is the hard part. SCDOT is redesigning the I-26 and I-526 interchange, with construction expected to begin in 2030, and king tides flood low-lying streets several times a year. A crew lead stuck on the Ravenel Bridge cannot answer the office line, and that is where jobs walk.
