Harrison County, MS

Settlement & growth (pre-1960)

Before European contact, the Biloxi and Pascagoula Native American tribes inhabited the coastal region, living off the Gulf’s abundant seafood and the pine forests inland. French explorers established the first permanent European settlement in 1699 at Fort Maurepas (near present-day Ocean Springs), making this area one of the oldest continuous European settlements on the Gulf Coast. The French, and later the Spanish, controlled the territory through the 18th century, leaving a legacy of Catholic parishes and place names that persist today.

After the United States acquired the region in the 1810 Mississippi Territory, Anglo-American settlers began arriving in earnest. The 1830s saw a wave of small farmers and planters from Georgia, the Carolinas, and Tennessee, drawn by cheap land and the promise of cotton cultivation along the coastal rivers. These early settlers established the towns of Biloxi, Gulfport, and Pass Christian as fishing villages and shipping ports. The county was officially formed in 1841, named after President William Henry Harrison, and its economy revolved around seafood, lumber, and maritime trade.

The post-Civil War period brought significant demographic change. Freed slaves remained in the area, forming the foundation of the county’s Black population, which concentrated in Biloxi’s east side and in rural communities like Lyman and Saucier. The late 19th century saw the arrival of European immigrants—primarily French, German, and Italian families—who worked in the seafood canneries and shipbuilding industries. Biloxi’s Point Cadet neighborhood became a hub for these immigrant communities, with Catholic churches and ethnic social clubs forming the backbone of social life.

The 20th century brought two transformative forces: the military and tourism. Keesler Air Force Base, established in Biloxi in 1941, became a major training center and economic engine, drawing military families from across the country. The base’s presence created a steady stream of domestic in-migration, particularly from the Midwest and Northeast, and helped diversify the local economy beyond fishing and lumber. Meanwhile, the rise of beach tourism along the Mississippi Sound turned Biloxi and Gulfport into resort destinations, attracting seasonal visitors and second-home buyers from New Orleans and the broader South. By 1960, Harrison County’s population had grown to roughly 120,000, with a majority-white population and a substantial Black minority concentrated in older neighborhoods.

Modern era (post-1965)

The 1965 Hart-Cellar Act had a limited direct impact on Harrison County compared to major metropolitan areas. The county’s foreign-born population remains low at just 2.1%, well below the national average. However, the post-1965 period saw a gradual increase in East/Southeast Asian immigration, primarily Vietnamese and Filipino families who arrived in the 1970s and 1980s. Many came as refugees or through family reunification, finding work in the seafood industry and the growing casino sector. Today, the East/Southeast Asian community makes up 2.1% of the population, with a visible presence in Biloxi’s Point Cadet area and along the beachfront. The Indian subcontinent community is very small at 0.2%, with no distinct enclave.

The most significant demographic shift since 1965 has been domestic, not international. The legalization of casino gambling in 1990 transformed the Gulf Coast economy, bringing a wave of new residents from across the United States. Casino resorts along the Biloxi-Gulfport beachfront attracted workers from the Rust Belt, the Northeast, and the West Coast, drawn by jobs in hospitality, construction, and management. This in-migration has been predominantly white and Hispanic, with the Hispanic share rising from negligible levels in 1990 to 6.7% today. Hispanic residents, many of Mexican and Central American origin, have concentrated in Gulfport and the unincorporated areas of the county, working in construction, landscaping, and the service industry.

Suburbanization has reshaped the county’s geography. The corridor between Gulfport and Biloxi has filled in with subdivisions, strip malls, and schools, while communities like D’Iberville, Woolmarket, and Long Beach have grown rapidly as bedroom communities. The county’s Black population, while still concentrated in older neighborhoods of Biloxi and Gulfport, has also suburbanized, with growing numbers in D’Iberville and Saucier. Hurricane Katrina in 2005 caused a temporary population decline of roughly 10%, but rebuilding efforts and federal investment in infrastructure and housing brought many residents back and attracted new ones seeking affordable coastal living.
