Of its 430 square miles, 418 are land and 12 are water,<br \/>\nabout 2.9 percent &mdash; most of it the Illinois River itself, which crosses the county through<br \/>\nMorris, and the Kankakee River, which joins the Des Plaines River near the county&#8217;s eastern<br \/>\nedge to form the Illinois. The Mazon River, a smaller tributary, drains the county&#8217;s southern<br \/>\ntownships; the fossil-rich shale along Mazon Creek produced Illinois&#8217;s state fossil, the Tully<br \/>\nMonster.<\/p>\n<p>Kendall County lies to the north, Will County to the east, Kankakee County to the southeast,<br \/>\nLivingston County to the south, and LaSalle County to the west. <a\nhref=\"https:\/\/townsvillages.com\/us\/will-county\/\">Will County<\/a>, <a\nhref=\"https:\/\/townsvillages.com\/us\/kankakee-county\/\">Kankakee County<\/a> and <a\nhref=\"https:\/\/townsvillages.com\/us\/lasalle-county\/\">LaSalle County<\/a> each have a profile on<br \/>\nthis site; Kendall County and Livingston County do not.<\/p>\n<h2>Demographics<\/h2>\n<p>Grundy County had a population of 52,533 at the 2020 census, and the latest estimate puts the<br \/>\ncounty near 54,052 residents. Channahon and Minooka, both shared with neighboring counties, and<br \/>\nMorris are the county&#8217;s largest communities. Median household income runs $92,235 (2023 ACS,<br \/>\nData USA), well above Illinois&#8217;s statewide figure of $80,306 (2023 ACS). Population density<br \/>\nworks out to roughly 126 people per square mile of land, reflecting the county&#8217;s position on<br \/>\nthe outer edge of the Chicago metropolitan area alongside large rural townships in its south and<br \/>\nwest.<\/p>\n<h2>Economy &amp; Local Life<\/h2>\n<p>Manufacturing employs the most workers in the county, about 3,292 people, followed by health<br \/>\ncare and social assistance at 3,215 and retail trade at 3,149 (Data USA, 2024). Lyondell Chemical<br \/>\nCompany, about five miles from Morris, is among the county&#8217;s larger private employers.<br \/>\nDresden Generating Station, a nuclear plant three miles from Morris, and two more nuclear stations<br \/>\nwithin 15 miles supply power to the Chicago area and anchor a sizeable share of the local<br \/>\nenergy-sector workforce. Coal City&#8217;s economy shifted away from the coal mining that gave the<br \/>\nvillage its name after the local mines closed, toward manufacturing and jobs commuting to the<br \/>\nDresden and Braidwood nuclear stations.<\/p>\n<h2>History<\/h2>\n<p>Illinois&#8217;s General Assembly formed Grundy County on 17 February 1841, carving it out of<br \/>\nLaSalle County. It was named for Felix Grundy, a Tennessee senator who served as United States<br \/>\nAttorney General under President Martin Van Buren. Morris, platted the following year, became the<br \/>\ncounty seat.<\/p>\n<p>On 16 February 1883, floodwater breached the Diamond Mine near what is now the village of<br \/>\nDiamond, killing 72 miners in one of Illinois&#8217;s deadliest mining disasters; a monument in<br \/>\nDiamond commemorates the dead. Coal remained the county&#8217;s dominant industry into the early<br \/>\n20th century before the mines exhausted their reserves and closed, and South Wilmington, Braceville<br \/>\nand Carbon Hill all trace their founding to that coal boom. On 3 April 1974, Morris became the<br \/>\nfirst Illinois community struck during that day&#8217;s Super Outbreak, though the tornado caused<br \/>\nonly minor damage in the city and no injuries.<\/p>\n<h2>Getting There<\/h2>\n<p>Interstate 80 runs east&#8211;west through the county, crossing Illinois Route 47 in Morris.<br \/>\nInterstate 55 passes through the county&#8217;s southwestern corner. US Route 6 and Illinois Routes<br \/>\n17, 47, 53 and 113 also cross Grundy County.<\/p>\n<ul>\n<li>Joliet &mdash; northeast via Interstate 80, in neighboring Will County<\/li>\n<li>Ottawa &mdash; west via Interstate 80, in neighboring LaSalle County<\/li>\n<li>Kankakee &mdash; southeast via Illinois Route 47, in neighboring Kankakee County<\/li>\n<li>Chicago &mdash; roughly an hour northeast via Interstate 80<\/li>\n<\/ul>\n<p>Chicago&#8217;s Midway and O&#8217;Hare airports, both northeast of the county, are the nearest<br \/>\nmajor commercial airports.
