As of the 2010 census, the population was 498,886. The county seat is West Chester. Chester County was one of the three original Pennsylvania counties created by William Penn in 1682. It was named for Chester, England. Chester County is part of the Philadelphia - Camden - Wilmington, PA - NJ - DE-MD Metropolitan Statistical Area. Eastern Chester County is home to many communities that comprise part of the Main Line western suburbs of Philadelphia, while part of its southernmost portion is considered suburban Wilmington, along with southwest Delaware County. Chester County is the highest - income county in Pennsylvania and 24th highest in the nation as measured by median household income ( as of 2010 ).

At that time, Chester County 's borders were Philadelphia County to the north, the ill - defined western edge of the colony ( approximately the Susquehanna River ) to the west, the Delaware River to the east, and Delaware and Maryland to the south. Chester County replaced the Pennsylvania portion of New Netherland / New York 's `` Upland '', which was officially eliminated when Pennsylvania was chartered on March 4, 1681, but did not cease to exist until June of that year. Much of the Welsh Tract was in eastern Chester County, and Welsh place names, given by early settlers, continue to predominate there. The fourth county in the state, Lancaster County, was formed from Chester County on May 10, 1729. On March 11, 1752, Berks County was formed from the northern section of Chester County, as well as parts of Lancaster and Philadelphia counties. The original Chester County seat was the city of Chester, a center of naval shipbuilding, at the eastern edge of the county. In an effort to accommodate the increased population of the western part of the county, the county seat was moved to a more central location in 1788 ; in order to mollify the eastern portion of the county, the village, known as Turk 's Head, was renamed West Chester. Apparently, this did not work : the eastern portion of the county separated from Chester County on September 26, 1789, becoming Delaware County. West Chester remained the seat of the reduced Chester County, and still is. Much of the history of Chester County arises from its location between Philadelphia and the Susquehanna River. The first road to `` the West '' ( meaning Lancaster County ) passed through the central part of Chester County, following the Great Valley westward ; with some re-alignments, it became the Lincoln Highway and later U.S. Route 30. This road is still named Lancaster Avenue in most of the Chester county towns it runs through. The first railroad ( which became the Pennsylvania Railroad ) followed much the same route, and the Reading Railroad progressed up the Schuylkill River to Reading. Industry tended to concentrate along the rail lines. Easy transportation allowed workers to commute to urban jobs, and the rise of the suburbs followed. To this day, the developed areas form `` fingers '' extending along major lines of transportation. During the American Revolutionary War, the Battle of Brandywine was fought at what is now the southeastern fringe of the county. The Valley Forge encampment was at the northeastern edge. Geography According to the U.S. Census Bureau, the county has a total area of 759 square miles ( 1,970 km ), of which 751 square miles ( 1,950 km ) is land and 8.7 square miles ( 23 km ) ( 1.1 % ) is water. The topography consists of rolling hills and valleys and it is part of the region known as the Piedmont. Watersheds that serve Chester County include the Octoraro, the Brandywine, and Chester creeks, and the Schuylkill River. Many of the soils are fertile, rich loam as much as twenty - four inches thick ; together with the temperate climate, this was long a major agricultural area. Because of its proximity to Philadelphia, Chester County has seen large waves of development over the past half - century due to suburbanization. Although development in Chester County has increased, agriculture is still a major part of the county 's economy, and the number of horse farms is increasing in the county. Mushroom growing is a specialty in the southern portion of the county. Elevations ( in feet ) : High point -- 1020 Welsh Mt., Honeybrook Twp.

The region was originally occupied by the Lenni Lenape people, who greeted European settlers in the seventeenth century with amity and kindness. British settlers were mostly English, Scotch - Irish and Welsh in ethnicity. From the late 19th to early 20th century, the industrial areas of the region, such as Coatesville, attracted immigrants and job seekers from Germany and Ireland, Eastern Europe, Italy, and the American rural South, with both black and white migrants coming north. Later Hispanic immigrants have included Puerto Ricans and, most recently, Mexicans. Long a primarily rural area, Chester County is now the fastest - growing county in the Delaware Valley ; it is one of the fastest growing in the entire Northeastern section of the United States. Religion Uwchlan Meetinghouse In keeping with its colonial history, Chester County is home to a number of historic Quaker buildings, including Birmingham, Birmingham Orthodox, Bradford, Caln, Old Kennett, Parkersville, Westtown, and Uwchlan meeting houses. Other historic religious buildings include St. Malachi Church, southeastern Pennsylvania 's oldest active Catholic mission church, and the Episcopal St. Mary 's, St. Paul 's, and St. Peter 's churches, and Washington Memorial Chapel. Also located in the county are the First Presbyterian Church of West Chester, Coventryville United Methodist Church, which is part of the Coventryville Historic District, and Beth Israel Congregation of Chester County, a Conservative synagogue in Coatesville, a site of Eastern European immigration in the 20th century.

Republican : 155,439 ( 43.87 % ) Democratic : 136,893 ( 38.64 % ) Other Political parties and no affiliation : 61,984 ( 17.49 % ) Chester County has historically been reliably Republican at the county level ; traditionally, it was the most conservative county on the Philadelphia side of Pennsylvania. In recent elections, however, it has been trending Democratic, though not as overwhelmingly as the rest of the Philadelphia suburbs. In 2000 Al Gore lost it by almost 10 percent but in 2004 George W. Bush defeated John Kerry by a much smaller margin of only 4.5 percent. Bob Casey, Jr. carried it by 10 % when he unseated incumbent Republican US Senator Rick Santorum in 2006. In 2008, Chester County sided with the rest of Pennsylvania and voted for Barack Obama by a much larger margin of 9 %, making him the first Democrat to carry it in a Presidential election since 1964. But, in 2009, with a smaller turnout, Republican candidates swept all county - row offices, winning with an average margin of 20 %. In 2012 the county voted for Republican candidate Mitt Romney, by a very small margin of about 500 votes. In 2016, despite Pennsylvania voting for a Republican presidential candidate for the first time since 1988, Chester County voted more Democratic than in 2012, with Hillary Clinton leading Donald Trump by over 25,000 votes or 9.4 percentage points ; a 4.8 percentage point swing from 2012. The only two statewide winners in 2016 to carry Chester County were U.S. Senator Pat Toomey ( R ) and Pennsylvania State Treasurer Joe Torsella ( D ). Republican candidates John Brown and John Rafferty carried Chester County, though both lost their races for Auditor General and Attorney General, respectively ( Rafferty, a State Senator whose district includes northern Chester County, carried the county by a slim margin of 50 votes ) Democrats have made gains in Chester County state legislative seats in recent elections. Democrat Andy Dinniman picked up the 19th Senate District in May 2006 in the special election to replace the late Robert Thompson. Democrat Barbara McIlvaine Smith picked up the open 156th House district in November 2006, winning by 28 votes and tipping the State - House majority to the Democrats. This was the first time that a Democrat had served part of Chester County as State Representative since Jim Gerlach ( who represented much of Chester County for 12 years in Congress ) unseated Sam Morris in 1990. In 2008, two more open House seats in the county went Democratic -- to Tom Houghton in the 13th and Paul Drucker in the 157th. In 2010, however, Chester County swung back to the GOP, with Republicans Dan Truitt ( who defeated McIlvaine Smith ), Warren Kampf ( who defeated Drucker ), and John Lawrence ( who defeated Houghton ) all elected to the State House. On November 8, 2017, Democrats made historic inroads in Chester County by winning their first County Row Office seats since 1799, picking up 4 row office seats.
