Ridgeland, SC – According to the Post and Courier, Jasper County in South Carolina’s Lowcountry has risen to the top spot as the fastest-growing county in the United States, based on recent U.S. Census Bureau data released in late March 2026. The county’s population surged by 6 percent from July 2024 to July 2025, adding nearly 2,200 residents and reaching a total of 38,533 people. This marked an improvement from the previous year’s 5.9 percent growth, which had placed Jasper third nationally.
Nestled in the southeastern corner of the state, Jasper County borders the Savannah River to the west, Beaufort County to the east, and Hampton County to the north. Much of the expansion has concentrated in the towns of Hardeeville and Ridgeland, fueled by an influx of retirees drawn to age-restricted communities such as Latitude Margaritaville Hilton Head and Sun City Hilton Head. These developments, home to around 13,000 residences, trace their origins to earlier booms on nearby Hilton Head Island that gradually spread westward.
County Council Chairman Joey Rowell highlighted the appeal of the region’s mild climate, natural beauty, and lower tax rates as key attractors for new residents. However, this rapid population growth has strained local services, particularly in primary healthcare for the aging demographic. Retirees have also expressed desires for additional retail and commercial amenities, which are emerging gradually to meet demand.
The surge in residents has intensified conflicts between developers and conservation advocates seeking to preserve the area’s rural character beyond urban centers. In September 2025, Ridgeland rejected a major annexation and development proposal that would have introduced thousands of homes and commercial spaces along S.C. Highway 462, a quiet rural route linking Interstate 95 to the Lowcountry. This decision followed years of contention, leaving the project’s future uncertain for now.
Conservation groups celebrated successes in protecting key properties, including Gregorie Neck, Chelsea, and the 600-acre Treble Hook Plantation near Gillisonville. The Treble Hook site will expand the existing 10,000-acre Coosawhatchie Wildlife Management Area (WMA), enhancing habitat preservation and public access for outdoor activities. These victories underscore ongoing efforts to balance expansion with environmental stewardship in the face of mounting development pressures.
Despite these gains, challenges persist. In February 2026, Jasper County Council approved the rezoning of a 265-acre northern parcel for a sand mining operation, passing by a 4-1 vote despite warnings from Councilmember Gene Ceccarelli about potential precedents for further industrial incursions. Environmental organizations, including the Coastal Conservation League and the S.C. Environmental Law Project, responded by filing a lawsuit shortly after to contest the approval.
Nationally, nine of the top 10 fastest-growing counties hail from southern states. Texas’ Waller and Kaufman counties followed Jasper with 5.7 percent growth each, while Georgia’s Jackson and Long counties recorded 5.3 percent and 5.2 percent, respectively. In terms of sheer numbers, Harris County, Texas (home to Houston), led with nearly 49,000 new residents.
Within South Carolina, Jasper County outpaced other rapid growers like Berkeley, Horry, Spartanburg, and Lancaster counties. Horry, in second place statewide, achieved a 3.3 percent increase. In contrast, neighboring Beaufort County experienced slower growth, adding about 1,400 residents for a 0.7 percent rate—less than half the state’s overall 1.5 percent average. Beaufort’s population stood at 204,233 as of July 2025, tying with Charleston County for the slowest among the state’s 10 largest counties.
Beaufort County Planning and Zoning Director Rob Merchant attributed sustained interest to the area’s environment, culture, and history, but emphasized the need for proactive management to protect these assets amid influxes. Traffic congestion remains a major grievance, exacerbated by external growth. During a March 23, 2026, Beaufort County Council meeting, Councilmember Logan Cunningham pointed to Jasper’s approval of 16,000 new homes in 2025—many yet to be built and close to county lines—as an impending burden on local infrastructure.
Rowell advised prospective movers to exercise patience, noting the Lowcountry’s deliberate pace and infrastructure challenges tied to population growth. As Jasper County navigates its newfound prominence, the interplay between economic vitality and conservation will shape its future trajectory in South Carolina’s dynamic Lowcountry region.
