Hamilton County is part of the [[Cincinnati metropolitan area|Cincinnati-Middletown, OH-KY-IN Metropolitan Statistical Area]].

==History==
The southern portion of Hamilton County was originally owned and surveyed by [[John Cleves Symmes]], and the region was a part of the [[Symmes Purchase]]. The first settlers rafted down the [[Ohio River]] in 1788 following the [[American Revolutionary War]]. They established the towns of [[History of Cincinnati#Losantiville|Losantiville]] (later Cincinnati), [[North Bend, Ohio|North Bend]], and [[Columbia Township, Hamilton County, Ohio|Columbia]].

Hamilton County was organized in 1790 by order of [[Arthur St. Clair]], governor of the Northwest Territory, as the second county in the [[United States Northwest Territory|Northwest Territory]]. Cincinnati was named as the seat. Residents named the county in honor of [[Alexander Hamilton]], who was the first [[Secretary of the Treasury]] of the [[United States]] and a founder of the Federalist Party. Its original boundaries were those defined for the Symmes purchase contract in 1788:<ref>However, the Symmes purchase was later reduced to just the southern third of the original tract.</ref> the Ohio River in the South, Great Miami River to the west, the Lesser Miami River to the east, and the Cuyahoga River to the North. Its area then included about one-eighth of Ohio and had about 2,000 inhabitants (not including the remaining Native Americans).

The county was greatly expanded in 1792 to include what is today the lower peninsula of Michigan. Since 1796, other counties were created from Hamilton, reducing the county to its present size. The county was the location of much of the [[Northwest Indian War]] before and after its organization.

The United States forcibly removed most of the [[Shawnee people|Shawnee]] and other Indian peoples to move to locations west of the [[Mississippi River]] in the 1820s.

Rapid growth occurred during the 1830s and 1840s as the area attracted many [[Germans|German]] and [[Irish people|Irish]] immigrants, especially after the [[Great Famine (Ireland)|Great Famine]] in Ireland and the revolutions in Germany in 1848.

During the [[American Civil War|Civil War]], [[Morgan's Raid]] (a [[Confederate States Army|Confederate]] [[Cavalry in the American Civil War|cavalry]] campaign from Kentucky) passed through the northern part of the county during the summer of 1863.

The [[Sharonville Engineer Depot]] was constructed by the United States Army in northern Hamilton County in 1942, and continued to be used by the [[General Services Administration]] and then the [[Defense Logistics Agency]] after 1949. It is currently mostly redeveloped for industrial purposes.

===Population===
The county's highest population was recorded in the 1970 U.S. Census. Since then, the county has lost population at an average rate of three percent per decade. Although Hamilton County is experiencing a decline in birth rates and has higher death rates in older age groups (cohorts), out-migration of residents is the key factor in population loss. In the last decade, this population loss has been reversed, and it is estimated that both Hamilton County and the City of Cincinnati have grown their populations.<ref name=pop>{{cite web|url=https://www.hamiltoncountyohio.gov/common/pages/DisplayFile.aspx?itemId=5398078|title=Population COMMUNITY COMPASS REPORT NO. 15-1|work=Hamilton County Regional Planning Commission|date=2004|access-date=March 1, 2020|archive-date=March 1, 2020|archive-url=https://web.archive.org/web/20200301183526/https://www.hamiltoncountyohio.gov/common/pages/DisplayFile.aspx%3FitemId%3D5398078|url-status=dead}}</ref>
The Cincinnati Metropolitan Statistical Area, over the last three decades has seen a 19 percent increase in population. Much of the region's growth has been through movement of Cincinnati and Hamilton County residents into neighboring counties.<ref name=pop/>

The county continued to lean Democratic, voting for Obama again in [[2012 United States presidential election in Ohio|2012]] and for Democratic candidate [[Hillary Clinton]] in [[2016 United States presidential election in Ohio|2016]]. In fact, it was one of the few counties in Ohio to swing toward the Democrats in 2016 even as the state as a whole swung toward the Republicans.

In other state elections, the county also tended to favor Republican candidates. [[Richard Cordray]] in his failed [[2018 Ohio gubernatorial election|2018]] bid was the first Democrat to win the county in a gubernatorial election since [[Dick Celeste]] in [[1982 Ohio gubernatorial election|1982]], and only the second since [[Michael DiSalle]] in [[1958 Ohio gubernatorial election|1958]].<ref>{{Cite web |title=1982 Gubernatorial General Election Results - Ohio |url=https://uselectionatlas.org/RESULTS/state.php?year=1982&off=5&elect=0&fips=39&f=0}}</ref><ref>{{Cite web |title=1958 Gubernatorial General Election Results - Ohio |url=https://uselectionatlas.org/RESULTS/state.php?year=1958&off=5&elect=0&fips=39&f=0}}</ref> In Senate elections, the county also tended to back Republicans, but has been won by [[Frank Lausche]] in [[1962 United States Senate election in Ohio|1962]], [[John Glenn]] in all four of his elections and [[Howard Metzenbaum]] and [[Sherrod Brown]] in two out of three elections for both ([[1982 United States Senate election in Ohio|1982]] and [[1988 United States Senate election in Ohio|1988]], and [[2012 United States Senate election in Ohio|2012]] and [[2018 United States Senate election in Ohio|2018]]).<ref>{{Cite web |title=Our Campaigns - OH US Senate Race - November 6, 1962 |url=https://www.ourcampaigns.com/RaceDetail.html?RaceID=27806 |access-date=April 19, 2022 |website=www.ourcampaigns.com}}</ref> In the [[2006 Ohio elections]], both [[Ted Strickland]] and [[Sherrod Brown]] lost the county by less than 2,000 votes while winning statewide by 24 and 12 points, respectively.

With the election of Democrat [[Stephanie Summerow Dumas]] in 2018 midterm elections, the Hamilton County Board of Commissioners was entirely Democratic for the first time ever.<ref>{{Cite web|url=https://www.wvxu.org/post/new-hamilton-county-commission-will-be-one-firsts|title=New Hamilton County Commission Will Be One Of Firsts|last=Rinehart|first=Bill|website=www.wvxu.org|language=en|access-date=January 16, 2020}}</ref> Democrats had previously regained majority control of the Board of Commissioners in 2016 with the election of [[Denise Driehaus]]. In 2019, longtime Democratic Commissioner [[Todd Portune]] announced his resignation from the Board due to health problems. Portune's Chief of Staff, Victoria Parks, was appointed to serve the remainder of his term (through the November 2020 general election). With Parks' appointment, the Board of Commissioners became for the first time all-female and majority Black.<ref name="London">{{Cite web|last=London|first=John|date=January 14, 2020|title=Hamilton County has first all-female commission|url=https://www.wlwt.com/article/hamilton-county-has-first-all-female-commission/30522022|access-date=January 16, 2020|website=WLWT|language=en}}</ref> In the November 2020 election, Democrat [[Alicia Reece]] was elected to fill Parks' seat, thereby retaining the Board's status as all-female and majority Black.<ref name=":1" />

Historically, due to its tight races and its position in the [[swing state]] of Ohio, Hamilton County was regarded as a crucial county to win in presidential elections. In 2012, ''[[The Washington Post]]'' named Hamilton as one of the seven most important counties in the country for that year's election.<ref>{{cite news|url=https://www.washingtonpost.com/news/the-fix/wp/2012/11/06/the-7-most-important-counties-in-election-2012/|title=The 7 most important counties in Election 2012|last=Blake|first=Aaron|date=November 6, 2012|newspaper=[[The Washington Post]]|access-date=January 23, 2018}}</ref> ''[[Time (magazine)|Time]]'' characterized Hamilton County's political scene as "a battle between conservative suburbs and a Democratic urban center, though Cincinnati is one of the most conservative metro areas in the Midwest."<ref>{{cite magazine|url=https://swampland.time.com/2012/10/29/the-keys-to-ohio-five-counties-that-could-decide-the-presidency/|title=The Keys to Ohio: Five Counties that Could Decide the Presidency|last=Altman|first=Alex|date=October 29, 2012|magazine=[[Time (magazine)|Time]]|access-date=January 23, 2018}}</ref> Those characterizations became less true in recent years. While many of Cincinnati's western suburbs, like Green and Delhi Townships, continue to strongly support Republican candidates, the city itself and most of its northern suburbs vote strongly Democratic.
