South Carolina migration surge keeps Charleston housing demand hot

South Carolina has ranked first in inbound migration for seven straight years, and Charleston-area movers say the trend is still showing up in daily bookings. The data points to continued population growth, broader economic pull and more arrivals from the Northeast and Mid-Atlantic.

Why it matters: - South Carolina's sustained inbound migration is adding pressure to Charleston-area housing, moving, schools and infrastructure. - The region's growth is now being driven by both lifestyle demand and a wider mix of jobs, which can keep relocation demand elevated. - Local movers are seeing more out-of-state families, remote workers and retirees choose the Lowcountry on different timelines than the traditional school-year move cycle.

What happened: - South Carolina topped the nation's inbound migration rankings for a seventh consecutive year, according to moveBuddha's 2026 Migration Report. - Newly released Census Bureau figures show the state gained roughly 68,000 net domestic migrants in the most recent measured year. - Saltwater Moving says its experience in the Charleston market matches those migration trends. - The Charleston metro area now exceeds an estimated 850,000 residents and is growing at roughly twice the national rate. - The National Association of Realtors named the Charleston region one of its top 10 Housing Hot Spots for 2026.

The details: - NAR linked the area's growth to a large share of millennial households, steady income growth and strong inbound migration from Washington, D.C., New York, Atlanta and Charlotte. - Berkeley County, home to Goose Creek, Hanahan and Moncks Corner, was among the fastest-growing counties in South Carolina in the latest Census data. - Berkeley County grew faster than Horry County, which includes the Myrtle Beach area. - More than 80% of South Carolina's population growth since the 2020 Census has been concentrated in just ten counties. - Berkeley and Charleston counties were both on that list. - Boeing's 787 Dreamliner assembly plant in North Charleston remains one of the region's largest private employers. - The Port of Charleston is now among the eight largest container ports in the country and is expanding terminal capacity to meet shipping demand. - Charleston's tech sector has grown into the Southeast's "Silicon Harbor," with well over 1,000 technology companies across software, cybersecurity and health tech. - The Medical University of South Carolina anchors a growing life sciences sector. - Saltwater Moving reports that much of its business now comes from people relocating from out of state, especially the Northeast, to Charleston and surrounding communities like Summerville, Goose Creek and Mount Pleasant. - Saltwater Moving has expanded service coverage across the Lowcountry, including downtown Charleston, Summerville, Moncks Corner and nearby beach communities. - The company's busiest months still track the broader relocation season, with bookings rising in spring and easing somewhat in summer as humidity and hurricane season set in. - Inquiries from out-of-state movers have stayed steady beyond the traditional peak.

Between the lines: - Charleston is no longer drawing newcomers for one reason alone. - Aerospace, port logistics, tech and healthcare are broadening the area's economic base and widening the pool of people who can justify a move. - The steady flow of remote workers and retirees suggests migration could remain resilient even if seasonal homebuying patterns soften. - For local businesses, sustained inflows can mean more demand for housing-related services, consumer spending and workforce growth.

What's next: - Saltwater Moving expects relocation demand to remain tied to spring move season, but it also expects off-cycle inquiries to stay elevated. - Continued growth in Berkeley and Charleston counties will likely keep pressure on roads, housing supply and local services. - The region's next growth test is whether infrastructure and housing can keep pace with migration without eroding affordability.

The bottom line: - Charleston remains one of the South's strongest magnets for new residents, and the data suggests the move-in wave is not slowing yet.
