Overview
Jackson County is a county administrative unit in the U.S. state of Missouri (state reference), located in the western portion of the state and forming a large part of the Kansas City metropolitan area. At the time of the 2010 census the county's population was recorded as 674,158, making it the second-most populous county in Missouri after St. Louis County. The county combines dense urban neighborhoods with suburban and rural districts.
County seats and government
Jackson County has two official county seats: Independence and Kansas City. This dual-seat arrangement reflects historical development: Independence was the early civic center and a departure point for 19th-century trails, while Kansas City's growth in the late 19th and 20th centuries shifted much commercial and population weight to the west. County government provides standard local services—courts, public safety, records, public health and infrastructure—under elected officials and administrative departments.
History
Jackson County was established on December 15, 1826. It was named for Andrew Jackson, who was elected President of the United States in 1828; the name reflects his popularity among many settlers of the period. The county's early importance springs from its position along the Missouri River and from Independence's role as a jumping-off point for the Santa Fe, Oregon and California Trails, routes widely used during westward expansion.
Economy, culture and transportation
Economically, Jackson County benefits from a mix of sectors: urban commerce, manufacturing and services concentrated in Kansas City; government, retail and cultural institutions in Independence and surrounding suburbs; and agricultural activity in outlying areas. The county is a transportation hub for the region, with river, rail and highway connections that have shaped its growth. Cultural contributions include the jazz and barbecue traditions associated with Kansas City and several museums and historic sites in Independence.
