Westchester is a neighborhood in the City of Los Angeles and the Westside Region of Los Angeles County, California.
It is home to Los Angeles International Airport, Loyola Marymount University, Otis College of Art and Design, and Westchester Enriched Sciences Magnet Schools (formerly Westchester High School).
The main part of Westchester is flanked by Playa Vista and Culver City on the north, Inglewood and Lennox on the east, Hawthorne on the southeast, Del Aire and El Segundo on the south and Playa del Rey on the west. It includes all of the Los Angeles International Airport. There is also a two-block-wide shoestring district that runs from the intersection of Centinela Avenue and La Cienega Boulevard north to 63rd Street and then east to Overhill Avenue, where it links with the Hyde Park neighborhood.
The main neighborhood's boundary lines are, generally, on the east: north-south on La Cienega Boulevard or the Inglewood city line; on the south: east-west on the city boundary with El Segundo or Imperial Highway; on the west: north-south on Pershing Drive and Westchester Parkway, then roughly north-south on a series of residential streets west of Westchester High School to the Playa Vista neighborhood.
Westchester began the 20th century as an agricultural area, growing a wide variety of crops in the dry, farming-friendly climate. The rapid development of the aerospace industry near Mines Field (as the Los Angeles Airport was then known), the move of then Loyola University to the area in 1928, and population growth in Los Angeles as a whole created a demand for housing in the area. Westchester hosted the cross country part of the eventing equestrian event for the 1932 Summer Olympics in Los Angeles.
In the late 1930s, real estate magnate Fritz Burns and his partner Fred W. Marlow  developed a tract of inexpensive prefabricated single-family homes on the site of a former hog farm at the intersection of Manchester and Sepulveda Boulevards. This community, dubbed "Westchester", grew as the aerospace industry boomed in World War II and afterward. A Los Angeles Times article in 1989 described the development as "a raw suburb", "created willy-nilly in the 1940s".
The area was predominantly residential. When the area had 30,000 residents, it was still lacking a police station, fire station, or hospital. It lacked a barber shop even by 1949.
The 1960s saw the introduction of airliners that could make trans-Pacific flights without refueling, causing a massive increase in air traffic at LAX. When the North Airfield Complex was constructed the increase in noise from jet takeoffs greatly decreased the desirability of the residential areas adjoining LAX. In response, the city of Los Angeles began a program of purchasing and condemning houses from noise-weary homeowners; as a result, a number of streets just north of the airport have been decommissioned, and the homes along those streets demolished. In all, Westchester lost 4,500 homes and 14,000 residents. The 18-hole Westchester golf course became a 15-hole course. In 2007 Los Angeles World Airport (LAWA) proposed another move of the north runway into Westchester; local opposition to LAX expansion (first proposed in the late 1990s) rose.
In February 2010, a NASA panel found that the north runway was safe and should stay as it is. That same month, LAWA broke ground on a $1.5 billion expansion of the Bradley International Terminal.
Home prices rose 25 percent in 2013–14 while most southern California communities were recovering much more slowly. A major factor has been the influx of technology companies in Playa Vista as the Silicon Beach phenomenon in west Los Angeles has spread. The community also experienced a boom in home additions or complete rehabilitation of traditional postwar ranch-style houses into larger two-story homes. The Howard Hughes Center was a significant addition to the neighborhood in 2001 next to the San Diego Freeway. Development continued until by 2015 the complex had 1.3 million square feet of office space (120,000 square metres) in high-rise buildings, 3,200 apartments, and an updated, renovated shopping mall.
A total of 39,480 people lived in Westchester's 10.81 square miles, according to the 2010 U.S. census, and that figure included the uninhabited acreage of the Los Angeles International Airport—resulting in a density of 3,652 people per square mile, among the lowest population densities in the city of Los Angeles but about average for the county. The median age was 35.6, about average for Los Angeles city. The percentage of people from age 19 through 34 was among the county's highest.
In 2010 Non-Hispanic whites made up 61.1% of the population, blacks 14.2%, Asians 12.0%, Native Hawaiian and other Pacific Islanders 0.3%, and others (including two or more races) at 11.9%. Those who identified themselves as Hispanic or Latino (of any race) were 18.2%.
In 2010, the mean family income for the area was $135,026 and the median family income was $106,302, both numbers high for the city. The percentage of families that earned more than $100,000 a year was 53.5%. Renters occupied 48.2% of the housing units, and homeowners occupied the rest. The average household size was 2.3 people, considered low for the city and county. The percentages of divorced men (8.6%) and divorced women (11.9%) were among the county's highest.The 2000 census counted 3,055 military veterans, 9.2% of the population, considered a high percentage for the city of Los Angeles but about average for the county.
Parks and recreation
The Westchester Recreation Center is in Westchester. The center includes an auditorium, barbecue pits, a lighted baseball diamond, lighted outdoor basketball courts, two indoor basketball courts, a children's play area, a community room, a lighted football field, an indoor gymnasium without weights, picnic tables, a lighted soccer field, and lighted tennis courts. The Westchester Pool, on the recreation center site, is an outdoor heated seasonal pool renovated in 2010. The Westchester Tennis Courts in the recreation center consist of ten lighted courts. A skate park is also located in the recreation center. The Westchester Golf Course is located just east of the recreation center.
The Westchester Senior Citizen Center has a 200-person auditorium, barbecue pits, a 20-person community room, a garden, a kitchen, picnic tables, and a stage. The 8-acre (3.2 ha) Carl E. Nielsen Youth Park is located in Westchester. In 1991, Los Angeles World Airports planned to pave over the park and use the lot as parking spaces and leased space to rental car companies. During that year, LAWA decided to keep the park open.
