Of its 402.44 square<br \/>\nmiles, 394.27 are land and 8.17 are water, about 2 percent &mdash; most of it Morse Reservoir, a<br \/>\n1,485-acre lake near Cicero built in 1956 as a water-supply reservoir, and Geist Reservoir, which<br \/>\nthe county shares with Marion County along its southeastern edge.<\/p>\n<p>Tipton County lies to the north, Madison County to the east, Hancock County to the southeast,<br \/>\nMarion County to the south, Boone County to the west and Clinton County to the northwest. <a\nhref=\"https:\/\/townsvillages.com\/us\/tipton-county\/\">Tipton County<\/a>, <a\nhref=\"https:\/\/townsvillages.com\/us\/madison-county-indiana\/\">Madison County<\/a>, <a\nhref=\"https:\/\/townsvillages.com\/us\/hancock-county-indiana\/\">Hancock County<\/a>, <a\nhref=\"https:\/\/townsvillages.com\/us\/marion-county-indiana\/\">Marion County<\/a>, <a\nhref=\"https:\/\/townsvillages.com\/us\/boone-county-indiana\/\">Boone County<\/a> and <a\nhref=\"https:\/\/townsvillages.com\/us\/clinton-county-indiana\/\">Clinton County<\/a> all border Hamilton<br \/>\ndirectly.<\/p>\n<h2>Demographics<\/h2>\n<p>Hamilton County had a population of 347,467 at the 2020 census, and the latest estimate puts<br \/>\nthe county near 387,036 residents by 2025. Carmel and Fishers are the two largest communities,<br \/>\ntogether holding well over half the county&#8217;s population even though neither is the county<br \/>\nseat. Median household income runs $121,530 as of 2024, according to Data USA, well above<br \/>\nIndiana&#8217;s 2023 statewide figure of $69,477 &mdash; Hamilton is regularly ranked the<br \/>\nhighest-income county in Indiana. Population density works out to roughly 881 people per square<br \/>\nmile of land, among the densest counties in the state outside Marion County itself.<\/p>\n<h2>Economy &amp; Local Life<\/h2>\n<p>Health care and social assistance employs the most workers in the county, about 30,326 people,<br \/>\nfollowed by professional, scientific and technical services at 24,225 and manufacturing at<br \/>\n21,521. Hamilton Southeastern Schools, based in Fishers, is the county&#8217;s single largest<br \/>\nemployer at roughly 2,626 staff. Westfield&#8217;s Grand Park Sports Complex, the largest youth<br \/>\nsports campus in the United States with 26 baseball and softball diamonds and 31 multipurpose<br \/>\nfields, has hosted the Indianapolis Colts&#8217; summer training camp since 2018 and draws more<br \/>\nthan 5.5 million visits a year. Noblesville is home to Ruoff Music Center, the Indianapolis<br \/>\narea&#8217;s main outdoor concert venue since 1989, and Fishers opened a $170 million event center<br \/>\nin November 2024 that now hosts the ECHL&#8217;s Indy Fuel hockey team. The county&#8217;s biggest<br \/>\nannual event is Carmel&#8217;s Christkindlmarkt, an open-air German-style Christmas market held<br \/>\neach November and December that draws more than 400,000 visitors.<\/p>\n<h2>History<\/h2>\n<p>Indiana&#8217;s General Assembly formed Hamilton County on 8 January 1823, naming it for<br \/>\nAlexander Hamilton, the first U.S. secretary of the treasury. William Conner and Josiah Polk<br \/>\nestablished Noblesville that same year as the county seat, and it was incorporated as a town in<br \/>\n1851; accounts differ on whether the name honors Senator James Noble or a woman named Lavina<br \/>\nNoble, to whom Polk was reportedly engaged.<\/p>\n<p>The county&#8217;s population stayed modest through the 19th and most of the 20th century,<br \/>\nclimbing sharply only after 1990 as Indianapolis suburbs pushed north; Noblesville alone grew from<br \/>\n28,590 residents in 2000 to 51,969 by 2010. Noblesville also carries a difficult chapter of<br \/>\nIndiana history: the 1925 trial of Ku Klux Klan leader D.C. Stephenson, held in the county<br \/>\ncourthouse, produced a conviction that broke the Klan&#8217;s political power across the state. On<br \/>\n1 January 2025, Sheridan completed a voter-approved consolidation of its town government with<br \/>\nAdams Township, one of the more unusual local-government changes in the county&#8217;s recent<br \/>\nhistory.<\/p>\n<h2>Getting There<\/h2>\n<p>Interstate 69 crosses the county through Fishers and Noblesville. US 31 and US 421 run<br \/>\nnorth-south through the county, along with State Roads 19, 32, 37, 38, 47 and 213.<\/p>\n<ul>\n<li>Indianapolis &mdash; about 20 miles south<\/li>\n<li>Anderson &mdash; about 20 miles east<\/li>\n<li>Kokomo &mdash; about 30 miles northwest<\/li>\n<li>Muncie &mdash; about 35 miles east<\/li>\n<\/ul>\n<p>Indianapolis Metropolitan Airport, a general-aviation field in Fishers, serves the county<br \/>\ndirectly. Indianapolis International Airport, roughly 30 miles southwest of Noblesville, is the<br \/>\nnearest major commercial airport.
