Geography
Clark County lies along the north bank of the Ohio River in the Knobstone Escarpment region, where the flat river bottomland gives way to steep, wooded hills known locally as “the Knobs.” The county’s northern and western reaches are rolling upland farm country drained by Silver Creek and its branches, while the southern edge along the river is the most developed, home to Jeffersonville, Clarksville, and the River Ridge Commerce Center on the site of the former Indiana Army Ammunition Plant.
Clark County borders Scott County to the north, Jefferson County, Indiana, to the northeast, Trimble County, Kentucky, to the east, Oldham County, Kentucky, across the Ohio River to the southeast, Jefferson County, Kentucky, to the south, Floyd County to the southwest, and Washington County to the west.
Demographics
Clark County had a population of 121,093 at the 2020 census, making it one of Indiana’s larger counties and the most populous on the Indiana side of the Louisville metro area. Jeffersonville and Clarksville are by far its largest communities, together holding a large majority of county residents along the river corridor. Median household income in the county runs close to the Indiana median of $69,477. With 372.86 square miles of land, the county’s overall density works out to roughly 325 people per square mile, though that figure masks a dense river corridor and sparsely settled Knobs uplands.
Economy & Local Life
The river corridor economy is built on logistics and distribution, anchored by the River Ridge Commerce Center in Jeffersonville, a large industrial and warehouse park built partly on former U.S. Army ammunition-plant land. Healthcare (Clark Memorial Health), retail along the Jeffersonville and Sellersburg corridors, and manufacturing round out the base. Clarksville’s riverfront is known locally for the historic Colgate clock, a longtime landmark visible from downtown Louisville. Charlestown State Park, on the county’s eastern edge, draws visitors to its Ohio River bluffs and hiking trails.
History
Clark County was organized on February 3, 1801, and is Indiana’s second-oldest county. It is named for General George Rogers Clark, whose Revolutionary War campaigns against British-held forts in the Illinois Country led Virginia to grant him and his soldiers a large tract of land here, known historically as Clark’s Grant, which shaped much of the county’s early settlement pattern. Jeffersonville, laid out on a plan attributed to Thomas Jefferson, grew as a river port and, later, a shipbuilding and manufacturing center directly across the falls of the Ohio from Louisville.
Getting There
Interstate 65 crosses the county north–south through Jeffersonville and Sellersburg, linking directly to downtown Louisville over the Ohio River. U.S. Route 31 and Indiana State Roads 3, 60, 62, 160, and 362 provide the secondary road network.
- Louisville, Kentucky — 1 mile south
- New Albany, Indiana — 7 miles southwest
- Corydon, Indiana — 25 miles west
