Kings County is a county in the U.S. state of California. The population was 152,982 at the 2010 census. The California Department of Finance estimated the county's population was 149,407 as of July 1, 2016. The county seat is Hanford.

Kings County comprises the Hanford-Corcoran, CA metropolitan statistical area, which is also included in the Visalia-Porterville-Hanford, CA combined statistical area. It is in the San Joaquin Valley, a rich agricultural region.


The area was inhabited for thousands of years by American Indians including the Tachi Yokuts tribe. It was colonized by Spain, Mexico and the United States.

An 1805 expedition probably led by Spanish Army Lieutenant Gabriel Moraga recorded discovering the river, which they named El Rio de los Santos Reyes (River of the Holy Kings) after the Three Wise Men of the Bible. At the time of the United States conquest in 1848, the new government changed the name to Kings River after which the county was named.

In 1880, a dispute over land titles between settlers and the Southern Pacific Railroad resulted in a bloody gun battle on a farm 5.6 mi (9.0 km) northwest of Hanford; seven men died. This event became known as the Mussel Slough Tragedy.

Kings County was formed in 1893 from the western part of Tulare County. In 1909, by an act of the state legislature, 208 square miles (540 km2) of Fresno County territory was added to the northwest portion of Kings County.

Settlers reclaimed Tulare Lake and its wetlands for agricultural development. In surface area, it was formerly the largest body of freshwater west of the Great Lakes, and supported a large population of migratory birds as well as local birds and wildlife. Monoculture has sharply reduced habitat for many species.

In 1928, oil was discovered in the Kettleman Hills located in the southwestern part of Kings County. The Kettleman North Dome Oil Field became one of the most productive oil fields in the United States.

In 1933 during the Great Depression, over 18,000 cotton pickers in the southern San Joaquin Valley, mostly migrant Mexican workers, went on strike. During the strike, 3,500 striking farm workers lived in a four-acre camp on the land of a small farmer on the outskirts of Corcoran. Ultimately, the federal government intervened to force both sides to negotiate a settlement.

Lemoore Army Airfield was established for training and defense during World War II. In 1961, the U.S. Navy opened NAS Lemoore 9 miles (14 km) west of Lemoore, not far from the earlier site.

The completion of the California Aqueduct in the early 1970s brought needed water for agriculture and domestic use to the westside of the county. .

Historic sites


According to the U.S. Census Bureau, the county has a total area of 1,392 square miles (3,610 km2), of which 1,389 square miles (3,600 km2) is land and 2.1 square miles (5.4 km2) (0.2%) is water.

Kings County is bordered on the north and northwest by Fresno County, on the east by Tulare County, on the south by Kern County and a small part of San Luis Obispo County and on the west by Monterey County.

Most of the historic Tulare Lake was within Kings County. Although reclaimed for farming late in the 19th century, it was the largest freshwater lake west of the Great Lakes.

The 2010 United States Census reported that Kings County had a population of 152,982. The census included inmates of the three men's state prisons. According to the California Department of Corrections and Rehabilitation, there were 18,640 inmates in Kings County prisons on March 31, 2010, which was 12.2% of the population. The inmate population had been reduced to 13,894 on December 31, 2013.

The U.S. Census does not identify how many residents are undocumented immigrants. However, the Public Policy Institute of California issued a report in July 2011, which estimated there were 9,000 illegal immigrants living in Kings County in 2008, which would be 5.8% of the county’s population.

According to the California Board of State and Community Corrections, Kings County had the highest incarceration rate of California's 58 counties in 2014 at 1,384 per 100,000 population. Statewide, the rate was 567 per 100,000.


As of the 2000 census, there were 129,461 people, 34,418 households, and 26,983 families residing in the county. However, the California Department of Finance estimates that the population had grown 154,434 as of January 1, 2008. The population density based on the 2000 census was 36/km² (93/sq mi). There were 36,563 housing units at an average density of 26 per square mile (10/km²). The racial makeup of the county was 53.7% White, 8.3% Black or African American, 1.7% Native American, 3.1% Asian, 0.2% Pacific Islander, 28.3% from other races, and 4.8% from two or more races. 43.6% of the population were Hispanic or Latino of any race. 7.1% were of Portuguese, 6.2% German, 5.3% Irish and 5.1% American ancestry according to Census 2000. 63.6% spoke English, 30.9% Spanish, 1.4% Tagalog, 1.4% Portuguese and 1.3% Samoan as their first language.

There were 34,418 households out of which 46.4% had children under the age of 18 living with them, 58.0% were married couples living together, 14.3% had a female householder with no husband present, and 21.6% were non-families. 17.0% of all households were made up of individuals and 6.8% had someone living alone who was 65 years of age or older. The average household size was 3.18 and the average family size was 3.56.

In the county, the population was spread out with 29.0% under the age of 18, 11.8% from 18 to 24, 35.0% from 25 to 44, 16.8% from 45 to 64, and 7.4% who were 65 years of age or older. The median age was 30 years in 2000, which had increased to 31.1 by the time of the 2010 census. For every 100 females there were 134.8 males. For every 100 females age 18 and over, there were 148.8 males. The ratio may be attributed to the presence of three men's state prisons in the county.


Kings County has a large annual celebration held each May called Kings County Homecoming Week. In 2015, the event was scaled back to one day and renamed Pioneer Days. The event returned as Kings County Homecoming Week in 2016 but without the traditional parade.
