Geography
Caldwell County sits in Kentucky’s Pennyroyal (Pennyrile) region, a karst limestone plateau of rolling farmland, sinkholes and hardwood ridges. The Tradewater River and Livingston Creek drain the county’s northern and western sections. Lake Barkley’s watershed reaches the county’s southwestern corner near the Lyon County line.
Caldwell County borders Crittenden County to the northwest, Webster County and Hopkins County to the northeast, Christian County to the southeast, Trigg County to the south, and Lyon County to the southwest.
Demographics
Caldwell County had 12,649 residents at the 2020 census, a density of about 37 people per square mile. Princeton (6,270) and Fredonia (372) are the county’s two largest communities; the remainder of the population lives in unincorporated rural areas. Median household income in the county runs below the Kentucky median of $61,118, consistent with the county’s agricultural and light-manufacturing economic base.
Economy & Local Life
Agriculture remains central to Caldwell County’s economy, particularly dark-fired tobacco, corn, soybeans and cattle. Manufacturing is anchored by a Bremner cookie and cracker plant in Princeton, one of the county’s largest employers. The University of Kentucky has operated a research and education center in the county since 1925, supporting local farmers with agronomy research. Princeton’s downtown historic district and the county’s rural crossroads communities carry on a strong small-town fair and farm-market calendar each fall.
History
Caldwell County was formed in 1809 from part of Livingston County and named for John Caldwell, who served as Kentucky’s second lieutenant governor and had taken part in George Rogers Clark’s 1786 Indian campaign. During the forced removal of the Cherokee in the winter of 1838, a detachment of the Trail of Tears passed through the county. In the early 1900s, Caldwell County was one of the counties caught up in the Black Patch Tobacco Wars (1904–1909), when growers’ associations used violence to enforce boycotts of tobacco buyers offering low prices. The county was legally dry for most of its history and did not allow county-wide alcohol sales until voters approved the change in 2013.
