Of its 469.6 square miles, 468.32 are land and 1.28 are water, about 0.3 percent &mdash; the county has no large natural lake, and the Little Wabash River, which runs past Louisville and Clay City, accounts for most of its surface water.<\/p>\n<p>Effingham County lies to the north, Jasper County to the northeast, Richland County to the east, Wayne County to the south, Marion County to the west, and Fayette County to the northwest. <a href=\"https:\/\/townsvillages.com\/us\/effingham-county-illinois\/\">Effingham County<\/a>, <a href=\"https:\/\/townsvillages.com\/us\/jasper-county-illinois\/\">Jasper County<\/a>, Richland County, <a href=\"https:\/\/townsvillages.com\/us\/wayne-county-illinois\/\">Wayne County<\/a>, <a href=\"https:\/\/townsvillages.com\/us\/marion-county-illinois\/\">Marion County<\/a> and <a href=\"https:\/\/townsvillages.com\/us\/fayette-county-illinois\/\">Fayette County<\/a> all border Clay County directly.<\/p>\n<h2>Demographics<\/h2>\n<p>Clay County had a population of 13,288 at the 2020 census, and the latest Census Bureau estimate puts the county near 12,793 residents by 2025, a decline typical of rural southeastern Illinois. Flora and Louisville are the two largest communities, together holding well over a third of the county&#8217;s population. Median household income runs $60,417, lower than Illinois&#8217;s statewide figure of $80,306 (2023 ACS). Population density works out to about 28.4 people per square mile of land, thin even by downstate Illinois standards.<\/p>\n<h2>Economy &amp; Local Life<\/h2>\n<p>Manufacturing employs the most workers in the county, about 1,214 people, followed by health care and social assistance at 924 and retail trade at 607. Agriculture still shapes the local economy outside the towns, with the bulk of Flora&#8217;s surrounding farmland devoted to crops and livestock. Oil discovered near Clay City in 1936 kept oil-related businesses active in the village for decades, and pumpjacks still work fields around the community today. Flora&#8217;s restored Baltimore &amp; Ohio Depot, built in 1917, now houses the local Chamber of Commerce and a small history museum.<\/p>\n<h2>History<\/h2>\n<p>The Illinois legislature authorized Clay County on 23 December 1824, and the first appointed commissioners met on 8 March 1825 to organize the county government. The county was named for Henry Clay, the Kentucky senator and statesman. Louisville, settled by the Lewis family along the Little Wabash River, became the county seat in 1842.<\/p>\n<p>Clay City traces its roots to 1810, when John McCawley opened a tavern and trading post near the site of the earlier settlement of Maysville. The modern village took shape in 1855, about a mile north of Maysville, after construction of the Ohio and Mississippi Railway. In 1936, oil was struck in the area, and the discovery built a local industry that has outlasted most of the county&#8217;s other 20th-century enterprises.<\/p>\n<p>In 1950, the U.S. Census Bureau designated Clay County as the mean center of population of the entire United States, a symbolic marker of the geographic middle of the American population at that decade&#8217;s count.<\/p>\n<h2>Getting There<\/h2>\n<p>US Route 45 and US Route 50 cross the county, along with Illinois Route 37; no interstate passes directly through Clay County, though Interstate 57 runs through Salem in neighboring Marion County.<\/p>\n<ul>\n<li>Effingham &mdash; about 25 miles north<\/li>\n<li>Salem &mdash; about 26 miles west<\/li>\n<\/ul>\n<p>No airport in the county offers scheduled commercial service; travelers generally use airports in the St. Louis or Evansville metro areas. Amtrak&#8217;s City of New Orleans, Illini and Saluki trains stop at the station in Centralia, to the southwest in Marion County.<\/p>\n<h2>Frequently Asked Questions<\/h2>\n<p><strong>Where is Clay County located?<\/strong><br \/>\nIt sits in southeastern Illinois, about 25 miles south of Effingham, bordered by Effingham, Jasper, Richland, Wayne, Marion and Fayette counties.<\/p>\n<p><strong>What is the population of Clay County?<\/strong><br \/>\n13,288 at the 2020 census, with a Census Bureau estimate near 12,793 by 2025.<\/p>\n<p><strong>How big is Clay County?<\/strong><br \/>\n469.6 square miles (1,216 km2), of which 468.32 square miles are land.<\/p>\n<p><strong>What is the county seat of Clay County?<\/strong><br \/>\nLouisville, the county seat since 1842, on the Little Wabash River.<\/p>\n<p><strong>How many towns and villages are in Clay County?<\/strong><br \/>\nOne city, Flora, and five villages &mdash; Clay City, Iola, Louisville, Sailor Springs and Xenia &mdash; plus ten unincorporated communities.<\/p>\n<p><strong>What ZIP codes does Clay County use?<\/strong><br \/>\n62839 for Flora, 62858 for Louisville, 62824 for Clay City and Sailor Springs, 62838 for Iola and 62899 for Xenia.<\/p>\n<p><strong>What is Clay County known for?<\/strong><br \/>\nBeing named the U.S. Census Bureau&#8217;s mean center of population in 1950, and the oil business built around Clay City after a 1936 discovery.<\/p>\n<p>More counties in this state: <a href=\"https:\/\/townsvillages.com\/us\/category\/illinois\/\">Towns and villages in Illinois<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Clay County is a county in Illinois, United States, about 25 miles south of Effingham.
