Grundy Center (2,796) and Reinbeck (1,662) are the two largest communities, together holding more than a third of the county&#8217;s population. Iowa&#8217;s 2023 median household income is $71,433; Grundy County, an agricultural county with a small-town population base, generally tracks close to that figure. Population density works out to roughly 24.6 people per square mile.<\/p>\n<h2>Economy &amp; Local Life<\/h2>\n<p>Grundy County&#8217;s economy is built on row-crop and livestock agriculture \u2014 corn, soybeans, and hog production dominate the surrounding land \u2014 supplemented by light manufacturing and services based in Grundy Center and Reinbeck. Grundy Center is home to the county&#8217;s public school district and the Grundy County Memorial Hospital. The county fair, held each summer in Grundy Center, remains the county&#8217;s largest annual community event.<\/p>\n<h2>History<\/h2>\n<p>Grundy County was created on January 15, 1851, and organized on December 25, 1856. It was named for Felix Grundy, a Tennessee politician who served as a U.S. senator, congressman, and U.S. attorney general under President Martin Van Buren. Like much of north-central Iowa, the county was settled in waves by farmers moving west after the Civil War, and its politics have been consistently Republican since organization, with only four exceptions in presidential elections since 1851.<\/p>\n<h2>Getting There<\/h2>\n<p>U.S. Route 20 crosses the county east\u2013west, and Iowa Highways 14, 57, and 175 connect its towns to the surrounding region.<\/p>\n<ul>\n<li>Waterloo \u2014 20 miles east<\/li>\n<li>Marshalltown \u2014 30 miles southwest<\/li>\n<li>Ames \u2014 45 miles southwest<\/li>\n<li>Cedar Falls \u2014 25 miles east<\/li>\n<\/ul>\n<p>The nearest commercial airport is Waterloo Regional Airport, east of the county in Black Hawk County.<\/p>\n<h2>Frequently Asked Questions<\/h2>\n<p><strong>Where is Grundy County, Iowa?<\/strong><br \/>\nIt is in the north-central part of Iowa, along the Iowa River watershed, between Waterloo and Marshalltown.<\/p>\n<p><strong>What is the population of Grundy County?<\/strong><br \/>\nGrundy County had 12,329 residents at the 2020 census.<\/p>\n<p><strong>How big is Grundy County?<\/strong><br \/>\nThe county covers 501.9 square miles (1,299.9 km2), almost entirely farmland.<\/p>\n<p><strong>What is the Grundy County seat?<\/strong><br \/>\nGrundy Center is the county seat.<\/p>\n<p><strong>How many towns are in Grundy County?<\/strong><br \/>\nNine incorporated cities \u2014 Grundy Center, Reinbeck, Dike, Conrad, Wellsburg, Holland, Stout, Beaman, and Morrison \u2014 plus four unincorporated communities.<\/p>\n<p><strong>What ZIP codes are in Grundy County?<\/strong><br \/>\nGrundy County&#8217;s ZIP codes run from 50609 (Beaman) to 50680 (Wellsburg), with 50638 covering the county seat, Grundy Center.<\/p>\n<p><strong>Who is Grundy County named after?<\/strong><br \/>\nFelix Grundy, a Tennessee senator, congressman, and U.S. attorney general under President Martin Van Buren.<\/p>\n<p>More counties in this state: <a href=\"https:\/\/townsvillages.com\/us\/category\/iowa\/\">Towns and villages in Iowa<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Grundy County is a county in Iowa, United States, along the Iowa River watershed in the north-central part of the state.
