Overview

Posey County is a county located in the southwestern corner of the United States state of Indiana. It had a population of 25,910 at the 2010 census. The administrative center and largest town is the Mount Vernon, which serves as the county seat. The county is predominantly rural, with settlements clustered around river corridors and small towns.

Geography and natural features

Posey County lies where major rivers shape the landscape. Its borders and waterways have influenced local land use: low floodplains and bottomlands are used for farming and wildlife habitat, while higher ground supports residential and commercial areas. Several state-managed wetlands and public hunting areas are important for migratory birds and outdoor recreation.

History and development

Organized in the early 1800s and named for Thomas Posey, an early territorial leader, the county grew as river transport and agriculture drove settlement. Towns developed around river ports and ferry crossings; over time roads and rail added industrial connections. Historic patterns—river commerce, farming, and small manufacturing—remain visible in the county's communities.

Economy and communities

The local economy blends agriculture, light manufacturing, and river-related commerce. Grain, soybeans and corn are typical crops on family farms, while the county's river terminals support shipping and some industrial employers. The county seat, Mount Vernon, functions as a service and administrative hub for the surrounding rural townships.
