Hamilton County, Ohio

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 Losantiville (later Cincinnati), North Bend, and Columbia.

Hamilton County was organized in 1790 by order of Arthur St. Clair, governor of the Northwest Territory, as the second county in the 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:However, the Symmes purchase was later reduced to just the southern third of the original tract. 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 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 German and Irish immigrants, especially after the Great Famine in Ireland and the revolutions in Germany in 1848.

During the Civil War, Morgan's Raid (a Confederate 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.

The county lies in a region of gentle hills formed by the slopes of the Ohio River valley and its tributaries. The Great Miami River, the Little Miami River, and the Mill Creek also contribute to this system of hillsides and valleys. No naturally occurring lakes exist, but three

major humanmade lakes are part of the Great Parks of Hamilton County.[https://web.archive.org/web/20161230161410/http://www.hcswcd.org/uploads/1/5/4/8/15484824/makingwaves.pdf Hamilton County Water Resources] The largest lake by far is Winton Woods Lake, covering 188 surface acres, followed by Miami Whitewater Lake, covering 85 surface acres, and Sharon Lake, covering 36 surface acres.

The county boundaries include the lowest point in Ohio, in Miami Township, where the Ohio River flows out of Ohio and into Indiana. This is the upper pool elevation behind the Markland Dam, {{convert|455|ft|m}} above sea level.{{Cite web

In the county, the population was spread out, with 25.80% under the age of 18, 9.60% from 18 to 24, 29.70% from 25 to 44, 21.50% from 45 to 64, and 13.50% who were 65 years of age or older.

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.{{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}}

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.

Hamilton County was historically rather conservative for an urban county. It long favored Republican candidates in national elections, but has trended Democratic in recent years. In 2008, Barack Obama was the first Democratic presidential candidate to win the county since 1964, and only the second since 1936. The county continued to lean Democratic, voting for Obama again in 2012 and for Democratic candidate Hillary Clinton in 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 bid was the first Democrat to win the county in a gubernatorial election since Dick Celeste in 1982, and only the second since Michael DiSalle in 1958.{{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}}{{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}} In Senate elections, the county also tended to back Republicans, but has been won by Frank Lausche in 1962, John Glenn in all four of his elections and Howard Metzenbaum and Sherrod Brown in two out of three elections for both (1982 and 1988, and 2012 and 2018).{{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}} 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.{{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}} 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.{{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}} 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.

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.{{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}} 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."{{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|access-date=January 23, 2018}} 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.
