St. Lucie County is a county on Florida's Atlantic coast, commonly considered part of the Treasure Coast region. The county operates a range of local services and information through its official county portals and is one of Florida's coastal counties within the state of Florida. The county seat is the city of Fort Pierce, though much of the county's recent population growth has occurred in Port St. Lucie and surrounding suburban areas.

Geography and environment

St. Lucie County includes barrier island beaches, the Indian River Lagoon estuary system, tidal rivers and inland flatlands. These coastal and estuarine environments support a diversity of birds, fish and other wildlife, and they are central to both recreation and local conservation efforts. Regional planning and mapping resources are available from state and regional agencies; consult regional resources for planning and environmental information.

History

The area now called St. Lucie County was shaped by Native American occupation, European exploration and later settlement tied to citrus, fishing and shipping. Over the 20th century the county's towns and cities expanded as transportation improved. Historic downtown Fort Pierce retains maritime and cultural landmarks; municipal archives and local historical societies preserve records and photographs at resources such as Fort Pierce resources.

Population and demographics

Population in St. Lucie County has increased substantially since mid‑20th century, driven by in‑migration, new housing and regional economic shifts. Official census counts and annual estimates show growth through the early 2000s and into the 21st century; for the latest figures consult government data portals and demographic estimates. The county's population includes a mix of longtime residents, retirees, working families and seasonal visitors.

Economy

The local economy combines tourism, health care, retail and services with construction, manufacturing, marine industries and remaining agricultural activity such as citrus in less urbanized areas. Waterfront facilities, marinas and commercial ports contribute to marine commerce and recreation. Economic development programs at the county and municipal level seek to balance growth with environmental protection.
