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 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:[5] the Ohio River in the South, Great Miami River to the west, the Lesser Miami River to the east, and the Cayuhoga 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 both 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.

Geography

According to the U.S. Census Bureau, the county has a total area of 413 square miles (1,070 km2), of which 406 square miles (1,050 km2) is land and 6.7 square miles (17 km2) (1.6%) is water.[6]

Geographic features

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 manmade lakes are part of the Great Parks of Hamilton County.[7] 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, 455 feet (139 m) above sea level.[8]

The highest land elevation in Hamilton County is the Rumpke Sanitary Landfill at 1,045 feet (319 m) above sea level in Colerain Township.

There were 377,364 housing units at an average density of 929.7 per square mile (359.0/km2).[16] The racial makeup of the county was 68.8% white, 25.7% black or African American, 2.0% Asian, 0.2% American Indian, 0.1% Pacific islander, 1.1% from other races, and 2.1% from two or more races.

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.[19] 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.[19]

Government

See also: Ohio county government

As of 2020, the members of the Hamilton Board of County Commissioners are Denise Driehaus, Stephanie Summerow Dumas, and Alicia Reece.[20]

Since 1963, the Board has employed an administrator to run the day-to-day operations of the county; the current administrator is Jeffrey Aluotto.[21] Other elected officers include Dusty Rhodes (Auditor), Joe Deters (Prosecutor), Charmaine McGuffey (Sheriff), Eric Beck (Engineer), Scott Crowley (Recorder), Jill Schiller (Treasurer), and Lakshmi Sammarco (Coroner).[21]

As of 2021, the elected Common Pleas Court include: Judge Jody Luebbers, Judge Lisa Allen, Judge Jennifer Branch, Judge Wende Cross, Judge Leslie Ghiz, Judge Robert Goering, Judge Tom Heekin, Judge Christian Jenkins, Judge Charles Kubicki, Judge Melba Marsh, Judge Terry Nestor, Judge Robert Ruehlman, Judge Nicole Sanders, Judge Megan Shanahan, Judge Alan Triggs, and Judge Christopher Wagner.[22]

Politics

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.[23][24] 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 both Howard Metzenbaum and Sherrod Brown in two out of three elections for both (1982 and 1988, and 2012 and 2018).[25] In 2006, 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.[26] 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.[27] 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.[20]

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.[28] 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."[29] 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.

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

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 19 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 19 Government EditSee also Ohio county government As of 2020 the members of the Hamilton Board of County

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 23 24 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 both Howard Metzenbaum and Sherrod Brown in two out of three elections for both 1982 and 1988 and 2012 and 2018 25 In 2006 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 26 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 27 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 20 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 28 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 29 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 United States presidential election results for Hamilton County Ohio 30 Year Republican Democratic Third partyNo No No 2020 177
