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

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.

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.

Communities

Westchester County has six city (New York), cities, 19 town (New York), towns, and 23 village (New York), 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 (New Rochelle, New York), Residence Park, Rochelle Park-Rochelle Heights Historic District, Rochelle Park and Heights and Sutton Manor (New Rochelle), Sutton Manor. The six Political subdivisions of New York State#City, cities in the county are: 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. The largest city in the county by population is

with over 211,000 residents. The city with the highest population density is Mount Vernon, New York, Mount Vernon with a density of 15,564 individuals per square mile. The towns of Harrison, Mount Kisco, and Scarsdale are coterminous municipality, 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 Political subdivisions of New York State#Hamlet, 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 Political subdivisions of New York State#Census-designated place, census-designated places (CDPs), which are defined by the U.S. United States Census Bureau, 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. Zip codes in Westchester often are not coterminous with the actual municipality borders, causing mailing addresses to sometimes differ from the actual municipal location in which a property resides. For instance, the zip codes for Bronxville, New York, Bronxville, Larchmont, New York, Larchmont, Rye, and Scarsdale, New York, Scarsdale contain large areas that lie outside of those municipalities. All of the towns have Justice Courts (New York), justice courts, and some of the villages do as well.

Politics

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, New York, 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 United States presidential election, 2008 presidential race, the seventh-highest percentage of any New York county. Currently, all three U.S. congressional representatives from Westchester County are Democrats. and 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 , 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. 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 2002 New York gubernatorial election, 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 Democratic 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. As of the 2021 elections the current composition is fifteen Democrats, one Republican 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, New York, Pocantico Hills. The county is also home to 42nd U.S. President Bill Clinton and Secretary of State Hillary Clinton, who live in Chappaqua, New York, Chappaqua. Former First Lady Barbara Bush grew up in Rye.
