Westchester County is located in the U.S. state of New York. It is the seventh most populated county in New York and the most populated north of New York City.[5] According to the 2020 United States Census, the county had a population of 1,004,457, an increase of 55,344 (5.8%) from the 949,113 counted at the 2010 Census. Situated in the Hudson Valley, Westchester covers an area of 450 square miles (1,200 km2), consisting of six cities, 19 towns, and 23 villages. Established in 1683, Westchester was named after the city of Chester, England.[6][7] The county seat is the city of White Plains, while the most populous municipality in the county is the city of Yonkers, with 211,569 residents per the 2020 U.S. Census.

The annual per capita income for Westchester was $67,813 in 2011. The 2011 median household income of $77,006 was the fifth highest in New York (after Nassau, Putnam, Suffolk, and Rockland counties) and the 47th highest in the United States.[8] By 2014, the county's median household income had risen to $83,422.[9] Westchester County ranks second in the state after New York County for median income per person, with a higher concentration of incomes in smaller households. Simultaneously, Westchester County had the highest property taxes of any county in the United States in 2013.[10]

Westchester County is one of the centrally located counties within the New York metropolitan area. The county is positioned with New York City, plus Nassau and Suffolk counties (on Long Island, across Long Island Sound), to its south; Putnam County to its north; Fairfield County, Connecticut to its east; and Rockland County and Bergen County, New Jersey across the Hudson River to the west. Westchester was the first suburban area of its scale in the world to develop, due mostly to the upper-middle-class development of entire communities in the late 19th century and the subsequent rapid population growth.[11] Because of Westchester's numerous road and mass transit connections to New York City, as well as its shared border with the Bronx, the 20th and 21st centuries have seen much of the county, particularly the southern portion, become nearly as densely developed as New York City itself.[citation needed]


At the time of European contact in the 16th and 17th centuries, the Native American inhabitants of present-day Westchester County were part of the Algonquian peoples, whose name for themselves was Lenape, meaning the people. They called the region Lenapehoking, which consisted of the area around and between the Delaware and Hudson Rivers. Several different tribes occupied the area, including The Manhattans, and the Weckquaesgeek and Siwanoy bands of the Wappinger in the south, and Tankiteke, Sintsink and Kitchawank Wappinger in the north.

The first European explorers to visit the Westchester area were Giovanni da Verrazzano in 1524 and Henry Hudson in 1609. Dutch settlers began arriving in the 1620s, followed by settlers from England in the 1640s. Westchester County was one of the original twelve counties of the Province of New York, created by an act of the New York General Assembly in 1683. At the time it included present-day Bronx County, and abutted then-Dutchess County to the north. By 1775, Westchester was the richest and most populous county in the colony of New York. Although the Revolutionary War devastated the county, recovery after the war was rapid. In 1788, five years after the end of the war, the county was divided into 20 towns. In 1798, the first federal census recorded a population of 24,000 for the county.

Two developments in the first half of the 19th century—the construction of the first Croton Dam and Aqueduct, and the coming of the railroad—had enormous impacts on the growth of Westchester. The Croton Dam and Aqueduct was begun in 1837 and completed in 1842; now a National Historic Landmark, the Croton Aqueduct is considered one of the great engineering achievements of the 19th century. In the 1840s, the first railroads were built in Westchester, and included the New York and Harlem Railroad, the Hudson River Railroad,[nb 2] and the New York and New Haven Railroad. The railroads often determined the growth of a town, and the population shifted from Northern to Southern Westchester. By 1860, the total county population was 99,000, with the most populated city being Yonkers.

The period following the American Civil War enabled entrepreneurs in the New York area to create fortunes, and many built large estates, such as Lyndhurst, in Westchester. During the latter half of the 19th century, Westchester's transportation system and labor force attracted a manufacturing base, particularly along the Hudson River and Nepperhan Creek. In 1874, the western portion of the present Bronx County was transferred to New York County, and in 1895 the remainder of the present Bronx County was also transferred to New York County. These would later split from Manhattan to form a county.

During the 20th century, the rural character of Westchester would transform into the suburban county known today. The Bronx River Parkway, completed in 1925, was the first modern, multi-lane limited-access roadway in North America. The development of Westchester's parks and parkway systems supported existing communities and encouraged the establishment of new ones, transforming the development pattern for Westchester. With the need for homes expanding after World War II, multistory apartment houses appeared in the urbanized areas of the county, while the market for single-family houses continued to expand. By 1950, the total county population was 625,816. Major interstate highways were constructed in Westchester during the 1950s and 1960s. The establishment of these roadways, along with the construction of the Tappan Zee Bridge, led to further growth in the county.

New York National Guard deployed at the New Rochelle Containment Zone which was the initial hotspot of the COVID-19 pandemic on the east coast of the United States

During the COVID-19 pandemic, on March 10th, the state government ordered a one square mile "containment zone" in the northern part of the city of New Rochelle. Part of New Rochelle is adjacent to the Bronx, where the majority of New York State's COVID-19 positive cases were (as of May 8, 350,000 out of 20 million residents). As of April 22 there were a total of 25,276 cases, 838 deaths, and 9,371 recoveries. As of May 22, 2020, there were between 30 and 35,000 cases going both by COVID-19 testing and serological samples, constituting the highest number of highest per capita infections in the world: 3% out of 1 million residents.[citation needed]


Harbors, islands and shoreline of New Rochelle

Westchester County is located in the New York metropolitan area and Downstate New York, north of New York City and south of Upstate New York. It shares its southern boundary with New York City and its northern border with Putnam County. It is bordered on the west side by the Hudson River and on the east side by the Long Island Sound and Fairfield County, Connecticut. According to the U.S. Census Bureau, the county has a total area of 500 square miles (1,300 km2), of which 430 square miles (1,100 km2) is land and 69 square miles (180 km2) (14%) is water.[12]

Where Pelham Manor meets Pelham Bay Park in the Bronx, the southern border of Westchester is just under 11 miles (18 km) from Columbus Circle in Manhattan. At over 2,700 acres (11 km2), Pelham Bay Park is the largest of New York City's parks, forming a substantial buffer between suburban Westchester and the urban Bronx, while Van Cortlandt Park to the west acts as a similar buffer.

Long Island Sound shore[edit]

Westchester's Long Island Sound shore is generally rocky, interspersed with tidal mud flats, marshes and wetlands, as well as several natural and artificially-maintained sand beaches. Municipal and county owned parks provide access to beaches, nature preserves and passive and active waterfront recreational facilities. Several large harbors lie along the shore including Milton Harbor in Rye, Mamaroneck Harbor, Larchmont Harbor, and Echo Bay, and the upper and lower harbors in southern New Rochelle.

A number of islands can be found off the Long Island Sound shore, most of which are located in New Rochelle. Davids' Island, the former location of the U.S. Army's Fort Slocum, is currently unoccupied but is slated for use as passive parkland; Glen Island, currently a Westchester Parks Department run beach and park, was one of the first amusement parks in the country serving as a summer resort at the turn of the twentieth century; Huckleberry Island is largely undeveloped, and has one of the largest rookeries in western Long Island Sound; Echo Island is owned and used by a private yacht club; Execution Rocks is the site of a 19th-century lighthouse listed on the National Register of Historic Places; Columbia, Pea, and Goose Islands are undeveloped; Clifford, Harrison and Tank Islands are part of the "Five Islands Park" and nature preserve; while Oak and Pine Islands are used as private residences.

Hudson River[edit]

The widest section of the Hudson River, at 3.6 miles (6 km), is found between the Westchester and Rockland County shorelines immediately north of Croton Point. In Colonial times, this area was called the Tappan Zee or Sea. The Hudson River is tidal and brackish through Westchester and contains a small number of estuarine marshes. Two bridges span the Hudson in Westchester: the Bear Mountain Bridge crosses at Cortlandt and the Tappan Zee Bridge at Tarrytown. Municipal, county and state-owned parks provide access to waterfront landmarks and sites, including Croton Point in Croton, Kingsland Point in Sleepy Hollow and JFK Memorial Marina in Yonkers.

The Hudson River waterfront in Westchester is in a transitional period, converting from primarily industrial uses to mixed residential, commercial, retail, and recreational uses. This transformation is most notable in Yonkers, Hastings-on-Hudson, Dobbs Ferry, Irvington, Tarrytown, Sleepy Hollow, Ossining, and Peekskill, where redevelopment projects are in various stages of design and completion. In 2004, the county began a project to create Westchester RiverWalk, a walkway along the Hudson River of 51.5 miles (80 km) which will provide pedestrian access between New York City and Putnam County. 32.9 miles of the route are complete and accessible.[13]

At 987 feet (301 m), the highest elevation in the county is a U.S. Coast and Geodetic Survey benchmark known as "Bailey" in Mountain Lakes Park near the Connecticut state line.[14] The lowest elevation is sea level, along both the Hudson and Long Island Sound.


The New Croton Reservoir is the largest of many in the county.

Westchester County is divided into six primary drainage basins or watersheds: the Upper and Lower Long Island Sound; and the Bronx, Upper Hudson, Lower Hudson, and Croton River basins. Within these primary drainage basins are approximately 60 smaller basins, or subwatersheds. The principal streams draining the southern part of the county include Beaver Swamp Brook, Blind Brook, Bronx River, Hutchinson River, Mamaroneck River, Saw Mill River, Sheldrake River, Stephenson Brook and Tibbetts Brook. The primary streams draining the central part of the county include Byram River, Kisco River, Mianus River, Mill River, Pocantico River and Silvermine River. The principal streams draining the northern part of the county include Dickey Brook, Furnace Brook, Hallocks Mill Brook, Hunter Brook, Muscoot River, Peekskill Hollow Brook, and Titicus River. The county contains several major reservoirs; The Croton system and the Kensico Reservoir are important components of the New York City water supply system. The system is a series of interconnected reservoirs and lakes in northern Westchester and Putnam Counties that provide 10% of New York City's water under normal conditions and up to 30% in times of drought. The components of the system include the New Croton Reservoir, the Cross River Reservoir, the Titicus Reservoir, the Amawalk Reservoir, and the Muscoot Reservoir. Other major reservoirs are the Kensico and Byram Lake Reservoir, while there are a number of smaller reservoirs throughout the county.

The Westchester County Department of Planning divides the county into North, Central and South sub-regions.[15]


The rock that underlies Manhattan and Westchester is chiefly gneiss and mica-schist, with layers of dolomitic marble and serpentine.


The climate of Westchester County is primarily a humid subtropical climate (Koppen Cfa), with higher elevations bordering on a humid continental climate. Winters are cold, wet, and occasionally snowy throughout the county, with more snow inland in higher elevations. Summers are hot inland but cooler towards the coast, with somewhat of a relative dryness in the early part of summer. Precipitation is plentiful and in some elevated areas reaches over 50 inches. Snowfall is more common in Westchester than in New York City, with the exception of the southeast of the county where snowfall is often between 20 and 25 inches. In January, inland areas have a low of 21-26°F and a high of 34-37 °F while coastal areas have a low of 27-30 °F and a high of 38-41 °F. In the summer, this effect is much milder. Coastal areas, including Mamaroneck, New Rochelle, Rye, and Port Chester have highs of 81-83 °F and lows of 68-73 °F, while inland highs will be 84-87 °F and lows will be 65-70 °F. Winds can be heavy, especially by the coast.

Municipalities in Westchester County, New York

Westchester County has six cities, 19 towns, and 23 villages.

Cities in Westchester have many well established sub-areas within the municipal boundaries. Many of these are similar to hamlets and date back to as early as the late 1600s such as Cooper's Corners in New Rochelle. These areas also include some of the first planned communities in the country such as New Rochelle's Residence Park, Rochelle Park and Heights and Sutton Manor.

The six cities in the county are:[22]

Name Population Area (mi2) Density
(Pop. per mi2)
Yonkers 195,976 20.3 10,818.2 1646 / 1854 4th most populated city in New York State
New Rochelle 77,062 13.2 6,973.5 1688 / 1899 7th most populated city in New York State
Mount Vernon 67,292 4.4 15,288 1664 / 1853 8th most populated city in New York State
White Plains 56,853 9.9 5,820 1721 11th most populated city in New York State, also Westchester County seat
Peekskill 23,583 5.5 5,189.7 1684 / 1816 29th most populated city in New York State
Rye 15,720 20.0 2,710 1660 / 1904 37th most populated city in New York State, also the name of a town

Any land area in the county that is not contained in one of the cities is in a town. A town may have from zero to multiple villages. A village can be located in more than one town, as two of Westchester's villages are.[nb 3] The largest city in the county by population is Yonkers with nearly 200,000 residents. The city with the highest population density is Mount Vernon with a density of 15,564 individuals per square mile.[23][24]

The towns of Harrison, Mount Kisco, and Scarsdale are coterminous with the village of the same name. Two villages are split between two towns - Briarcliff Manor crosses the border between Ossining town and Mount Pleasant, and Mamaroneck village straddles the boundary between Mamaroneck town and Rye town.

With the exception of the towns of Rye, Pelham, Harrison, Mount Kisco, and Scarsdale, all the towns contain area and residents which do not belong to any village. These areas may contain communities referred to as hamlets, or "unincorporated areas". Hamlets have no legal status and depend upon the town for all municipal government and services. There are also areas called census-designated places (CDPs), which are defined by the U.S. Census Bureau for statistical purposes only. A CDP may or may not correspond to a hamlet.

Because some municipalities have the same name, it is often necessary to indicate whether one is referring to the city, town, village, or hamlet. For example, the town of Rye is completely separate from the city of Rye. Pelham is the name of a town and also of a village in the town. The village of Mamaroneck is located partially in the town of Mamaroneck and partially in the town of Rye, but has nothing to do with the city of Rye.

All of the towns have justice courts, and some of the villages do as well.

The towns are listed as follows:[25]

  • Town
    • Villages (if any), one per bullet
    • CDPs (if any), all listed on a single bullet
    • Communities not in a village or CDP (if any), all listed on a single bullet
(The list of towns, villages, and CDPs is complete. The listing of additional communities should not be considered complete.)


Due to its proximity to New York City, many Fortune 500 companies are headquartered[26] in Westchester county, including:

High technology[edit]

Tech Valley is a marketing name for the eastern part of New York State, including the Hudson Valley and the Capital District.[27] The term originated in 1998 to promote the Greater Albany metropolitan area as a competitor to regions such as Silicon Valley and Boston. It has since grown to represent the counties in New York between IBM's Westchester County plants in the south and the Canada–U.S. border to the north.


Westchester County has also developed a burgeoning biotechnology sector in the 21st century, with over US$1 billion in planned private investment as of 2016,[28] spurring Westchester Magazine to nickname the county Biochester.[29] In April 2017, county officials unveiled plans for an 80-acre, 3 million square-foot biotechnology hub to be built with US$1.2 billion in private investment on vacant land adjacent to Westchester Medical Center in Valhalla; the bioscience center, a public-private partnership, is anticipated to create 12,000 new jobs and include over 2.25 million square feet of biotechnology research space.[30][31]


Westchester County contains 48 public school districts,[32] nearly 120 private college-preparatory and parochial schools, and 15 colleges and universities. Many public and private high schools are continuously ranked among the best in New York State and the United States.[33][34] Public schools in the county are largely funded by local property taxes, and the median annual property-tax bill for Westchester County residents was $13,842 in 2013, the highest in the United States.[10] According to the 2018 rankings provided by the education website Niche, taking into account public comments, 28 of the top 100 school districts in the state of New York were located in Westchester County.[35]

Westchester County generally leans toward the political left. It last voted for the Republican nominee for president in 1988.

Historically, Westchester County was a classic "Yankee Republican" county. It supported Republican presidential candidates in all but two elections from 1896 to 1988. The only exceptions were 1912, when the GOP was divided between William Howard Taft and Theodore Roosevelt, and 1964, when Lyndon B. Johnson won a national landslide and swept every county in New York. However, it swung Democratic in the early 1990s—much like other New York City suburbs. In the most recent national elections, Westchester voters tended to be far more Democratic than the national average. In fact, Westchester, after New York City and Albany County, has produced the biggest margins for statewide Democrats in recent years. Democratic voters are mainly concentrated in the more populated southern and central parts of the county. More than 63 percent of Westchester County voters voted for Barack Obama in the 2008 presidential race, the seventh-highest percentage of any New York county.

Currently, all three U.S. congressional representatives from Westchester County are Democrats. Mondaire Jones and Jamaal Bowman represent most of the county. Jones' district covers most of the county's central and northwestern portions, including White Plains, Chappaqua, and Tarrytown, and reaches into Rockland County. Bowman's district is based in the Bronx, but includes most of the southern half of the county, including Yonkers, Mount Vernon, New Rochelle and Rye. The northeastern portion of the county is represented by Democrat Sean Patrick Maloney, a former advisor to Bill Clinton, who was elected in 2012, defeating Republican incumbent Nan Hayworth. Maloney's district includes the towns of Bedford, Somers, Pound Ridge, North Salem, Lewisboro, and a portion of North Castle.[41]

However, Republicans remain competitive with Democrats in state and local elections. For instance, it voted for Republican George Pataki, by a margin of 23.07% against Democratic candidate, Carl McCall in the gubernatorial race of 2002, and by 26.22% in 1998. Pataki hails from Westchester; he previously served as mayor of Peekskill and represented part of the county in the state Assembly and state Senate prior to being elected governor.

In 1998, County Executive Andrew Spano became just the second Democrat to hold the post in at least a half-century. In 2006, county legislator Andrea Stewart-Cousins defeated 20-year incumbent Nicholas Spano for a seat in the New York State Senate in a rematch of the 2004 race, which she had lost by only 18 votes. His brother, Assembly Member Mike Spano, switched parties in July 2007 to become a Democrat. District attorney Janet DiFiore also switched parties from Republican to Democrat in August 2007. In 2009, Republican Rob Astorino ousted three-term county executive Andy Spano, who had the endorsement of the New York Conservative Party, winning in a landslide. Astorino became the first Republican county executive since Andrew O'Rourke left the post in 1997. In 2011, the GOP broke the Democratic two-thirds majority in the county legislature by picking up two seats. However, two of the Democrats formed a coalition with the Republicans to control the board, with a Republican becoming vice-chair. In 2017 Democrats gained three seats to take outright control of the board. In 2019 Democrats gained two seats and in 2020 the last remaining Republican switched parties to become a Democrat. The current composition is sixteen Democrats and one Conservative.

Westchester County was the home of U.S. Vice President Nelson Rockefeller, who occupied the Kykuit mansion near the hamlet of Pocantico Hills.

The county is also home to 42nd U.S. President Bill Clinton and Secretary of State Hillary Clinton, who live in Chappaqua. Former First Lady Barbara Bush grew up in Rye.

Former U.S. President Donald Trump owns a home in Bedford. The 230-acre Seven Springs estate was acquired by Trump in 1996.[43]

Law enforcement and emergency services[edit]

There are currently 42 local police agencies located in Westchester County. These agencies frequently work with one another and with other agencies, including county, state, and federal law enforcement agencies responsible for protecting Westchester County.

Westchester County has a wide array of emergency services and is the home to 58 fire departments, 42 ambulance services, three Haz-Mat teams, a volunteer technical rescue team, a fire academy and a fire investigations unit. Each department has career, volunteer or a combination of personnel. Westchester County Department of Emergency Services operates the main dispatching system for EMS and fire departments, located in Valhalla. The department also provides numerous support services for the various agencies throughout the county.

The Career Chief's Association, a cooperative of career fire departments, also operates the Special Operations Task Force. The force consists of six squad companies that can be rapidly assembled for a major hazardous materials incident, CBRNE event, collapse or confined space rescue, or other incident requiring a large number of HazMat or rescue technicians. Over 700 firefighters, police officers and EMS providers were trained to be part of this effort and serve over half the population of Westchester County including Yonkers, Mount Vernon, New Rochelle, White Plains, Scarsdale, Eastchester, and the Fairview, Hartsdale, and Greenville Fire Departments in the Town of Greenburgh.


Notable county-wide media outlets include:

  • The Daily Voice, a news website for Fairfield and Westchester Counties.
  • El Sol, a Spanish news website covering Connecticut and Westchester.
  • The Hudson Independent, a monthly newspaper serving Tarrytown, Sleepy Hollow and Irvington.
  • The Journal News, a daily newspaper and news website for Westchester, Rockland, and Putnam.

  • The Scarsdale Inquirer, a weekly newspaper that serves the residents of Scarsdale and Greenburgh.


The Tappan Zee Bridge connecting Tarrytown to South Nyack

The combination of the county's numerous roadways and bridges, proximity to New York City, and the county's large population all lead to substantial traffic enforcement and busy local courts.

Transportation routes have been responsible for the county's development patterns, with city and town growth being most pronounced along these corridors.[citation needed] There are five mostly north–south corridors and three which traverse the county in the east–west direction. The north–south routes are (going from west to east): S. Route 9/Albany Post Rd/Broadway Corridor, the Saw Mill River Parkway Corridor, the Sprain Brook Parkway, the Hutchinson River Parkway, and the I-95/New England Thruway. The east–west corridors are, from south to north: the Cross County Parkway, the Cross Westchester Expressway/I-287, and the U.S. 202 corridor.[44]

Major roadways[edit]


The Tappan Zee Bridge connects Tarrytown in Westchester to South Nyack in Rockland County, across the Hudson River; a $4 billion replacement for the original bridge began construction in 2013 and opened in 2017, and was renamed the Governor Mario M. Cuomo Bridge.[45] The Bear Mountain Bridge crosses the Hudson from the town of Cortlandt to Orange County.

Public transit[edit]

Westchester County Airport serves the county, and is adjacent to White Plains. Bus service is provided by the Bee-Line Bus System (owned by the Westchester County Department of Public Works and Transportation) within Westchester and to/from the Bronx, Manhattan, and Putnam County. Additionally, the MTA Bus Company runs to and from Getty Square in Yonkers to Midtown Manhattan. The Hudson Link operates express bus routes from city centers and train stations in Tarrytown and White Plains to Nyack, Nanuet, Spring Valley in Rockland County on the opposite side of the Hudson River.

Additionally, NY Waterway operates a water ferry service between Ossining in Westchester and Haverstraw in Rockland County.


Amtrak serves Croton-Harmon, New Rochelle, and Yonkers. Commuter rail service in Westchester is provided by Metro-North Railroad (operated by the Metropolitan Transportation Authority). Metro-North operates three lines in the county; west to east, they are the Hudson, the Harlem, and the New Haven lines. These are former operations of the New York Central and the New York, New Haven and Hartford railroads (and their successors, Penn Central and Conrail), each of which stops in the Bronx between Westchester and Manhattan.

In popular culture[edit]

The Old Dutch Church in Sleepy Hollow

Westchester County has been the home of many novelists, including Washington Irving. His most famous work is "The Legend of Sleepy Hollow", which is set at the Old Dutch Church of Sleepy Hollow among other locations in Sleepy Hollow, New York. The story has inspired a variety of works, including the 2013 television series Sleepy Hollow, set in the modern village.

In the X-Men multimedia series, the X-Mansion is located on the Titicus Reservoir, on (fictional) Graymalkin Lane, outside of Salem Center.[46] At the mansion, Professor Charles Xavier runs the Xavier "School for Gifted Youngsters" to educate mutant children and keeps a headquarters for the X-Men.[47]

One of the most successful films shot in the county was the 1988 film Big. While the majority of the film takes place in New York City, the amusement park scenes were filmed in Rye Playland in Westchester.[48]

American singer and songwriter Loudon Wainwright III recorded a song titled "Westchester County" for his 1983 LP record Fame and Wealth. It recounts his postwar upbringing in Bedford, Westchester County, New York.

In print media, the area is a frequent setting of the Nero Wolfe detective stories by Rex Stout, which ran from 1934 to 1975. An early documented mention of Westchester County is in the Trixie Belden series (which ran from 1948 to 1986). The series was set in Sleepyside-on-Hudson, a fictional village in the Hudson Valley. The original author, Julie Campbell Tatham, modeled the fictional Crabapple Farm in Sleepyside after her own home at Wolf Hollow on Glendale Road in Ossining. She also mentioned it in her last work in the series: Cherry Ames, Country Doctor's Nurse. Westchester is the primary setting and residence of the main characters in The Clique young adult novel series by Lisi Harrison. In Edward Lewis Wallant's novel The Pawnbroker, the main character Sol Nazerman lives in Mount Vernon.

In television, an early broadcast media presentation of Westchester County was on The Dick Van Dyke Show (1961–1966), whose main characters live in New Rochelle. Much was made of their suburban setting and Rob's separate world from New York City. The 1970s sitcom Maude was set in Tuckahoe.[49] In the final season of the American sitcom Friends, the characters Monica and Chandler moved from New York City to live in Westchester. In the CBS sitcom How I Met Your Mother, Future Ted and his family live in Westchester. In the AMC show Mad Men, Ossining is home to main characters Don Draper and his family. From season 4, Don lives in Manhattan and Betty lives with Henry Francis and the children in Rye. The animated show Big Mouth is also set in Westchester County, where creator Nick Kroll grew up.[50]
