Harris County is located in the U.S. state of Texas, located in the southeastern part of the state near Galveston Bay. As of the 2010 census, the population was 4,092,459, making it the most populous county in Texas and the third most populous county in the United States. Its county seat is Houston, the largest city in Texas and fourth largest city in the United States. The county was founded in 1836 and organized in 1837. It is named for John Richardson Harris, who founded the town of Harrisburg on Buffalo Bayou in 1826. According to a July 2018 census estimate, Harris County's population had grown to 4,698,619, comprising over 16% of Texas's population. Harris County is included in the nine-county Houston–The Woodlands–Sugar Land metropolitan statistical area, which is the fifth most populous metropolitan area in the United States.

Human remains date habitation to about 4,000 BC. Other evidence of humans in the area dates from about 1,400 BC, 1 AD, and later in the first millennium. The region became uninhabited from 1 AD until European contact. On the other hand, little European activity predates 1821. ?lvar N??ez Cabeza de Vaca may have visited the area in 1529. French traders recorded passing through in the 18th century. Spaniards attempted to establish a fort in the area around the same time, but did not persist for long.

The first recorded European settlers in Harris County arrived in 1822. Their schooner sailed into Galveston Bay and ran aground on the Red Fish Bar. Some of those passengers traveled further up the bay system, but it is not known whether they settled up Buffalo Bayou or the San Jacinto River. One of these passengers, a Mr. Ryder, settled at what is now known as Morgan's Point, Texas. Also in 1822, John Iiams settled his family at Cedar Point after sailing from Berwick's Bay, Louisiana. Dr. Johnson Hunter arrived just after Iiams. He also wrecked his boat near Galveston. He settled at Morgan's Point and was a grantee of land there. Nathaniel Lynch settled in the area and operated a ferry.

In 1824, the land empresario, Stephen F. Austin convened at the house of William Scott for the purpose of conveying titles for Mexican headrights. He was joined by the land commissioner, Baron von Bastrop, and Austin's secretary, Samuel May Williams. About thirty families gained legal titles to land in what would later be known as Harris County. A few immigrants settled on Buffalo Bayou in these early years, including Moses Callahan, Ezekial Thomas, and the Vince brothers.

Nicolas Clopper arrived in the Galveston Bay area from Ohio in the 1820s. He attempted to develop Buffalo Bayou as a trading conduit for the Brazos River valley. He acquired land at Morgan's Point in 1826. John Richardson Harris (1790–1829), for whom the county was later named, arrived in 1824. Harris had moved his family to Sainte Genevieve, Missouri Territory, where they had been residing until the early 1820s.

Harris was granted a league of land (about 4,428 acres) at Buffalo Bayou. He platted the town of Harrisburg in 1826, while he established a trading post and a grist mill there. He ran boats transporting goods between New Orleans and Harrisburg until his death in the fall of 1829.

The First Congress of the Republic of Texas established Harrisburg County on December 22, 1836. The original county boundaries included Galveston Island, but were redrawn to its current configuration in May 1838.

The area has had a number of severe weather events, such as:

The list only includes counties with a population over 65,000 for comparability.

Racial and ethnic demographics
As of 2014 Census estimates, Harris County had a population of 4,441,370 people.

The racial and ethnic makeup of the county was 40.8% Hispanic or Latino. The population was 31.4% non-Hispanic white, 19.5% non-Hispanic black, 1.1% Native American, 7.0% Asian, 0.1% Pacific Islander.

This assumes that the net migration rate is equal to one half of that of 1990–2000.

The Houston Area Asian Survey of the Kinder Institute of Urban Research Houston Area Survey stated that between 1990 and 2000, the Asian population in Harris County increased by 76%. Between 2000 and 2010, it increased by 45%. The Asian ethnic groups in Harris County have differing levels of educational attainment, religion, political views, and income. During that year, in Harris County, 50% of the county's Asian immigrants have postgraduate degrees. As of 2013 28% of Harris County Asians have household incomes of over $75,000. The report stated that many Asians were in earlier stages of careers and were younger, leading to lower incomes.

In 2014, the county had 1,607 religious organizations, the third most out of all U.S. counties.


Harris County Criminal Courts Building
In 2000, 1,961,993 residents of Harris County spoke English only. The five largest foreign languages in the county were Spanish or Spanish Creole (1,106,883 speakers), Vietnamese (53,311 speakers), Chinese (33,003 speakers), French including Cajun and Patois (33,003 speakers), and Urdu (14,595 speakers). Among those who spoke other languages, 46% of Spanish speakers, 37% of Vietnamese speakers, 50% of Chinese speakers, 85% of French speakers, and 72% of Urdu speakers said that they spoke English at least "very well".

Political views
In 2013, Allen Turner of the Houston Chronicle said that residents of Harris County were "consistently conservative in elections" and that they were, according to a Rice University Kinder Institute for Urban Research opinion poll, "surprisingly liberal on topics such as immigration, gun control and equal matrimonial rights for same-sex couples". Harris is regarded as a moderate or swing county in Texas, and has been a bellwether in Presidential elections, voting for winners of every Presidential election from 2000 through 2012 (both Barack Obama and Texas resident George W. Bush have won the county).

As a result of the Obama sweep in 2008, many Democratic candidates in contests for lower-level offices also benefited, and many Republican incumbents were replaced by Democrats in the Harris County courthouse. Some of the defeated Republican district court judges were later re-appointed to vacant District Court benches by Governor Rick Perry. In 2018, Democrats swept the court capturing all 59 seats on the civil, criminal, family, juvenile and probate courts.

The Kinder Institute's Houston Survey in 2018 found that from 2014 through 2018 the number of Houston residents who supported adoption of children by same-sex couples climbed above 50% and remained there, while in 2017 over 56% of residents reported gay or lesbian persons among their circle of close personal friends. A 2013 opinion poll had found that 46% of Harris County residents supported same-sex marriage, up from 37% in 2001. Just above 82% favored offering illegal immigrants a path to citizenship provided they speak English and have no criminal record, holding from 83% in 2013, which was up from 19% in 2009. In 2013, 87% supported background checks for all firearms, the latest year that question was included in the Kinder Houston Survey. This measure has moved up steadily from 60% in 1985 to 69% in 2000.

Automobile ownership
As of U.S. Census figures current as of 1997, 9% of residents in Harris County did not own automobiles. This figure does not include people who own cars, but do not have enough money to repair the automobiles. As of that year, while the average income of all residents of the county was $41,000 (equivalent to $65,300 in 2019), the average income of households without cars was $13,000 (equivalent to $20,700 in 2019).

Educational attainment
In 2011, according to the nonprofit Children at Risk, one-third of students at public high schools in Harris County do not graduate.

Government and politics
County governments serve as agents of the state, with responsibilities defined in the Texas Constitution. Counties are governed by the commissioners' court. Each Texas county has four precinct commissioners and a county judge. Although this body is called a court, it conducts the general business of the county and oversees financial matters. The commissioners court may hire personnel to run major departments, such as health and human services.

Besides the county judge and commissioners, the other elective offices found in most counties include the county attorney, county and district clerks, county treasurer, sheriff, tax assessor-collector, justices of the peace, and constables. As a part of the checks and balances system, counties have an auditor appointed by the district courts.

Historically, Harris County voted Republican at the presidential level from the mid-20th century until 2008; Barack Obama was the first Democrat to win the county since Texas native Lyndon Johnson in 1964. Democratic strength is found in the city of Houston. Suburban areas such as Cypress, Spring, and Katy in the county's western and northern areas, tend to be strongly Republican. In 2016, Hillary Clinton won the county by the largest margin for a Democrat since 1964. The Democratic Party performed very strongly in the county during the 2018 elections.

County facilities
The 1910 county courthouse was renovated in the 1950s to update its systems. Some residents, such as Martin Dreyer, a Houston Chronicle reporter, were disturbed by modernization of the building, saying its character had been ruined. In the 21st century, the facility received another major renovation. Completed in 2011, the $50 million, eight-year project was designed to restore notable historic aspects of the courthouse while providing for contemporary communication and building needs.

The Texas First Court of Appeals and the Texas Fourteenth Court of Appeals, since September 3, 2010, are located in the 1910 Harris County courthouse. Previously they were located on the campus of the South Texas College of Law.

The Harris County Jail Complex of the Harris County Sheriff's Office (HCSO) is the largest in Texas, and one of the largest in the nation. In July, 2012, the facility held 9,113 prisoners. To handle overcrowding in the facility, the county had to ship inmates to other counties and some are housed out of the state.

County services
The Harris County Flood Control District manages the effects of flooding in the county.

The Harris County Sheriff's Office operates jail facilities and is the primary provider of law enforcement services to the unincorporated areas of the county. The sheriff is the conservator of the peace in the county. The Harris County jail facilities are in northern downtown on the north side of the Buffalo Bayou. The 1200 Jail, the 1307 Jail, (originally a TDCJ facility, leased by the county), and the 701 Jail (formed from existing warehouse storage space) are on the same site.

The Community Services Department provides community services. The department maintains the 20 acres (8.1 ha) Oates Road Cemetery (also known as the Harris County Cemetery) for indigents in eastern Houston, near the former Southern Bible College. In March 2010, the county adopted a cremation first policy, meaning that the default preference for most indigents is to have them cremated instead of buried. As of 2010, the county authorized the Community Services Department to purchase about 50 acres (20 ha) of land in the Huffman area so the county will have additional spaces for indigent burials.

The Harris County Housing Authority (HCHA) is a governmental nonprofit corporation which addresses the need for quality affordable housing. The HCHA has been recognized by the U.S. Department of Housing and Urban Development as the highest performing housing authority in the region and was recently named one of America's 10 best Public Housing Authorities. Guy R. Rankin, IV is Chief Executive Officer of Harris County Housing Authority (HCHA).

State government
The Texas Department of Criminal Justice operates some correctional facilities in Harris County, including:

Kegans Unit, located in Downtown Houston, is a state jail for men. It is in the north of downtown along the north side of the Buffalo Bayou, next to the county facilities.
Pam Lychner Unit, named after Pam Lychner and located in unincorporated northeast Harris County, east of the city of Humble, is a state jail for men.
As of 2001, Kegans and Lychner serves male state jail offenders from Harris County, with Kegans getting lower-risk offenders and Lychner getting higher-risk and special-needs offenders. If both of the male state jails in Harris County are full, excess offenders go to the Gist Unit in Jefferson County. Female state jail offenders from Harris County go to the Plane Unit in Liberty County.

The South Texas Intermediate Sanction Facility Unit, a parole confinement facility for males operated by Global Expertise in Outsourcing, is in downtown Houston, west of Minute Maid Park.

Law enforcement
As of 2018 there are over 60 law enforcement agencies operating in the county. They include: the Harris County Sheriff's Office, the Harris County Constable Office, the Houston Police Department, METRO Police Department, other municipal police departments, and school district police departments.

The combined yearly sum spent by these agencies circa 2018 was $1.6 billion. That year the Rice University Kinder Institute for Urban Research released a report advocating for consolidating several of these agencies as a way of saving taxpayer money.


Hewlett-Packard United States offices, formerly headquarters of Compaq
See also: Economy of Houston
In 2000, the largest employers in Harris County were Administaff, Compaq, Continental Airlines, Memorial Hermann Healthcare System, and Southwestern Bell.

The University of Houston System's annual impact on the Houston-area's economy equates to that of a major corporation: $1.1 billion in new funds attracted annually to the Houston area, $3.13 billion in total economic benefit, and 24,000 local jobs generated. This is in addition to the 12,500 new graduates the UH System produces every year who enter the workforce in Houston and throughout Texas. These degree-holders tend to stay in Houston. After five years, 80.5% of graduates are still living and working in the region.

In 2009, 20% of the office space in northwest Harris County was vacant. As of that year, more office space is being built; in 2010, northwest Harris will have twice the amount of office space that it had in 2009. The vacancy rate in the area near Farm to Market Road 1960 and Texas State Highway 249 in north Harris County was 53% in 2009.

Various companies are headquartered in incorporated and unincorporated areas throughout Harris County.

Academy Sports and Outdoors, a sporting goods retailer, has its corporate offices and product distribution center in unincorporated western Harris County. Hewlett-Packard operates its United States region office in a complex northwest unincorporated Harris County; the complex formerly belonged to Compaq prior to Compaq's merger with HP. Smith International has its headquarters in the Greenspoint district and in an unincorporated area in Harris County. BJ Services Company has its headquarters in the Spring Branch district and in unincorporated Harris County. Cybersoft Technologies has its headquarters in an unincorporated area. In 2012 Noble Energy announced that it was consolidating its headquarters and two other Greater Houston offices into a 10-story building on the former Compaq headquarters property in unincorporated Harris County. Goya Foods previously had its Texas offices in an unincorporated area in the county.

General Electric operates an aeroderivative division facility on Jacintoport in unincorporated Harris County. Randall's Food Markets, a subsidiary of Safeway Inc., has its distribution center in unincorporated Harris County.

In 2008, KBR announced that it will open a new office facility in an unincorporated area in western Harris County. In December KBR said that it would not continue with the plans due to a weakened economy. In January 2009 KBR announced that it will not open the new office facility.
