Jasper County, the rural, sparsely-populated zone separating the Hilton Head Island area from the Georgia border, is once again the fastest-growing county in the U.S.

Data released Thursday by the U.S. Census Bureau show Jasper was the fastest-growing county in the U.S. by percentage growth. The population rose by 6% between July 1, 2024 and July 1, 2025.

Jasper’s population was 28,811 on April 1, 2020, 36,338 on July 1, 2024 and 38,533 on July 1, 2025.

Anchored by Hardeeville along the Interstate 95 corridor, Jasper County has been signaled out by the Census for its high growth rate multiple times. Its housing stock increased by 8.4% between 2023 and 2024, making it the fastest-growing county in terms of housing units during that time period. A new Buc-ees is scheduled to come to the area near Exit 8, and the county’s portion of I-95 is also undergoing a major transformation.

Notable housing projects include Carolina Station, a 2,600-acre development with 3,800 homes, retail shops, restaurants, parks, and trails. Home prices are expected to start around $300,000, according to Island Packet archives.

Trilogy Investment Co. is also building a total of 650 new homes across two Jasper properties. One of those sites is part of the massive East Argent development, which will bring 10,000 homes and apartments, 1.5 million square feet of retail and office space, 1,300 of passive and recreational park space and a new YMCA. East Argent is described as the largest residential development in Hardeeville’s history.
