Johnson County is a county in the U.S. state of Kansas, along the border of the state of Missouri. Its county seat is Olathe.[5] As of the 2020 census, the population was 609,863, the most populous county in Kansas.[3] The county was named after Thomas Johnson, a Methodist missionary who was one of the state's first settlers. Largely suburban, the county contains a number of suburbs of Kansas City, Missouri, including Overland Park, a principal city of and second most populous city in the Kansas City Metropolitan Area.[6][7]


This was part of the large territory of the Osage people, who occupied lands up to present-day Saint Louis, Missouri. After the Indian Removal, the United States government reserved much of this area as Indian territory for a reservation for the Shawnee people, who were relocated from east of the Mississippi River in the upper Midwest.

The Santa Fe Trail and Oregon–California Trail, which pass through nearby Independence, Missouri, also passed through the county. Johnson County was established in 1855 as one of the first counties in the newly organized Kansas Territory; it was named for American missionary Thomas Johnson.[8] The renowned gunfighter Wild Bill Hickok settled for a time in the county, becoming constable of Monticello Township in 1858.

Johnson County was the site of many battles between abolitionists and pro-slavery advocates during the period of Bleeding Kansas, prior to the residents voting on whether slavery would be allowed in the territory. In 1862 during the American Civil War, Confederate guerrillas from nearby Missouri, led by William Quantrill, raided the Johnson County communities of Olathe and Spring Hill. They killed half a dozen men and destroyed numerous homes and businesses.[9]

The county was largely rural until the early 20th century, when housing subdivisions were developed in the northeastern portion of the county adjacent to Kansas City, Missouri. Developer J. C. Nichols spurred the boom in 1914 when he built the Mission Hills Country Club to lure upscale residents who previously had been reluctant to move from Missouri to Kansas.[10] Suburban development continued at a steady pace until the close of World War II.

Following the war, the pace of development exploded, triggered by the return of veterans in need of housing, construction of highways that facilitated commuting from suburbs, and the pent-up demand for new housing. The US Supreme Court ruling in Brown v. Board of Education (1954) ruled that segregation of public schools was unconstitutional. Integration of public schools in Kansas City, Missouri, resulted in many white families leaving the inner city, resulting in increased migration to the county for new housing and what were considered higher quality public schools, generally an indicator of higher economic status. From the mid-1980s, the pace of growth increased significantly, with the county adding 100,000 residents each decade between the 1990 census and 2010 census.

The 1952 Johnson County Courthouse was closed in 2020, then demolished in 2021.[1] It was replaced by a seven-story courthouse in 2021 after over two years of construction. This new courthouse is the county's fourth building.[2]

According to the United States Census Bureau, the county has a total area of 480 square miles (1,200 km2), of which 473 square miles (1,230 km2) is land and 6.5 square miles (17 km2) (1.4%) is water.[11]


The natural topography of the county consists of gently rolling terrain. The Kansas River forms a portion of the northwest boundary of the county. The elevation generally increases from north to south as the distance from the Kansas and Missouri rivers increases.

Watersheds and streams[edit]

The county is drained by the watersheds of the Kansas, Blue, and Marais des Cygnes, all of which are part of the Missouri River watershed. Located in northeastern Kansas, the county receives plentiful rainfall. The county contains numerous small streams, including Kill Creek, Mill Creek, Turkey Creek, Indian Creek, Brush Creek, Tomahawk Creek, the Blue River, Bull Creek and Little Bull Creek.

Kill Creek begins in the southwest portion of the county and flows northward into the Kansas River at De Soto. Mill Creek begins in the central portion of the county in Olathe, flowing northward it empties into the Kansas River at Shawnee. Turkey Creek and Brush Creek each begin in northeast Johnson County. Turkey Creek flows northeastward into Wyandotte County and joins the Kansas River just before its confluence with the Missouri River at Kaw Point. Brush Creek flows east-northeastward through Prairie Village and Mission Hills, entering Kansas City, Missouri, within the median of Ward Parkway and passing the Country Club Plaza before emptying into the Blue River east of the Country Club Plaza and north of Swope Park. Indian Creek begins in the southern portion of Olathe and Tomahawk Creek begins in south Overland Park. Each flows northeastward meeting in Leawood, where the stream retains the name of Indian Creek, just before crossing the state line and entering the Blue River in Kansas City, Missouri. The Blue River begins in rural southern Johnson County and flows north-northeastward through the southeastern portion of the county and crossing the state line just east of the intersection of 151st Street and Kenneth Road in southern Overland Park. The Blue River flows through southern and eastern Kansas City before joining the Missouri River. Bull Creek and Little Bull Creek begin in rural southwestern Johnson County and flow southward where they enter Hillsdale Lake before continuing into Miami County, eventually joining the Marais des Cygnes at Paola.

Flora and fauna[edit]

The county consists primarily of prairie grassland with corridors of forested areas along streams and rivers.

Johnson County is entirely located within Kansas's 3rd congressional district, which has been represented by Democrat Sharice Davids since 2019. The two U.S. Senators from Kansas are Republicans Roger Marshall and Jerry Moran.

Johnson County has traditionally been considered a Republican stronghold. From 1920 through 2016, it voted for the GOP in every presidential election. This included the 1964 election, in which Barry Goldwater carried the county by nine points even as he lost Kansas statewide; the last time the Republicans have failed to carry the state.[23][24] Earlier, it was one of the few counties where Franklin Roosevelt was shut out in all four of his campaigns, though FDR only lost the county by two votes in his 42-state landslide of 1932.

However, in 2016, Johnson County voted for Republican presidential nominee Donald Trump by less than a three-point margin, as the GOP's shift towards right-wing populism was considered a poor fit for the county's many moderate voters. In 2020, Joe Biden became the first Democrat to win Johnson County since Woodrow Wilson 104 years earlier, winning the county by an 8% margin. Biden's share of the vote was also the most ever won by a Democrat in Johnson County. The county's leftward trend was also reflected in the state's recent U.S. Senate elections in 2020 and 2022, where the Democratic candidates won the county despite losing statewide; prior to those elections, Johnson County had never gone to a Democrat in an election for either of Kansas's Senate seats.

State representation[edit]

Johnson County is home to 25 Kansas state representatives and 9 Kansas state senators. 13 out of 25 of Johnson County's representatives are Republicans, as are 6 of the county's 9 senators.[25][26] Numerous Republicans from the area identify as moderates, compared to some of the more ideological hard-liners from other parts of the state. Differences between moderates and the more hard-line members can most commonly be seen on social issues, the most infamous being the numerous debates about the state's school finance formula in 2004[27] and 2014–2018.[28][29][30][31]

County government and unincorporated areas[edit]

The county government is administered by an elected, seven-member Board of County Commissioners, with six elected from single-member districts and one at-large.[32] Governance of the county is divided into six districts. The county government has full jurisdiction of the unincorporated areas of the county and limited jurisdiction of those areas of the county within incorporated places. For instance, decisions regarding the regulation of land use, development and zoning in unincorporated areas of the county are the responsibility of the county government, whereas such decisions for areas within incorporated places are the jurisdiction of the incorporated city of which the property is a part.

Sales taxes[edit]

The current sales tax rate in Johnson County is 7.975%, higher than the 6.5% rate in Wyandotte (where Kansas City, Kansas is located).[33] The sales tax rates of each of the surrounding counties are nearly the same as the rate in Johnson County.[33] Individual cities have additional sales taxes.

Property taxes[edit]

Property taxes are a conglomeration of state, county, city, and school district taxes. Property tax rates are generally lower in Johnson County because property values in the county are higher than in other counties throughout Kansas.

The Johnson County Sheriff's Office runs the jails at Olathe and New Century,[36] and patrols the unincorporated parts of Johnson County as well as the cities of Edgerton and DeSoto.[37]

In 2019, the county announced that it is creating a new task force with shared jurisdiction between neighboring Miami and Franklin counties to combat crime.[38]

In April 2024, Johnson County Sheriff Calvin Hayden claimed that he "had a search warrant in hand" when local election officials "decided in a hurry to destroy" ballots from 2019, 2020 and 2021, despite Kansas state law ordering the regular destruction of old ballots, and the local officials having informed Hayden in November 2023 that they would move to destroy the old ballots, which Hayden had asked to be preserved during his investigation of an election software firm. The local prosecutors' office said that it was "unaware of any search warrant being submitted to a judge for review". In May 2024, when Hayden was questioned on which judge approved his search warrant, Hayden responded: "there's no judge"; when the questioner replied: "A judge has to sign a search warrant to be valid", Hayden responded: "I didn’t say it was valid".[39][40]

According to the 2010 Census Bureau, the education attainment of the population 25 years and over: 95.6% high school graduate or higher, 51.1% bachelor's degree or higher, and 17.9% graduate or professional degree.[19]

The Johnson County Library has 13 branches.[41]

Unified school districts[edit]

Colleges and universities[edit]


Johnson County has a grid network through most of the county, with a road every mile. The grid has facilitated rapid growth and easy access. Interstate 435 runs through much of the county, and serves as a developmental "border" in the northbound–southbound portion. The westbound–eastbound part of I-435 divides the county into a northern and southern section. The northern section is older, while the southern portion is the fastest-growing area in Johnson County, containing a massive volume of new homes.[citation needed]

The Johnson County numbered street grid generally begins at 47th Street, the Wyandotte County line (the lowest numbered street is 40th Street in Bonner Springs), and is a continuation of the adjacent Kansas City, Missouri, street grid. The grid continues to 215th Street, and into Miami County (with somewhat different named roads) to 407th Street at the Miami-Linn county line, with most suburban development ending around 167th Street. Named streets in the grid run from State Line Road (1900 West) to County Line Road (40699 West) at the Douglas County line. A portion of the grid extends north from Westwood into the Rosedale area in Kansas City, Kansas.

Another principal highway running through the area is Interstate 35, which runs diagonally through the county, entering it near Downtown Kansas City, and continuing through Olathe and Gardner. Outside the county, it eventually leads to Duluth, Minnesota in the north and the US–Mexico border in the south. U.S. 69 also serves Johnson County, entering from Wyandotte County at the south end of Interstate 635. Much of U.S. 69 within the county is freeway; this freeway eventually heads south and connects to Fort Scott and the rest of southeast Kansas.

Unincorporated communities[edit]


Johnson County was originally divided into nine townships, two of which have since been eliminated by the annexation of all their territory into independent municipalities. All of the cities are considered governmentally independent and are excluded from the census figures for the townships. In the following table, the population center is the largest city (or cities) included in that township's population total, if it is of a significant size.
