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.

Politics


Voter registration

As of November 18, 2024, there were 396,404 registered voters in Chester County.


Election results

Chester County has historically been reliably Republican at the county level. After voting Democratic in 1856 for Pennsylvania native James Buchanan, it only did so three more times in the next 160 years—in 1912, 1964, and 2008. In recent elections, however, the county has been trending Democratic, although not as overwhelmingly as its fellow Philadelphia Main Line, Main Line counties of Montgomery County, Pennsylvania, Montgomery and Delaware County, Pennsylvania, Delaware. It remains the most conservative of these three. In 2000, George W. Bush defeated Al Gore in the county by almost 10%, but in 2004, John Kerry cut Bush's margin of victory by over half, to just 4.5%. In 2008, Chester County voted for Barack Obama by 9%. 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 the Republican presidential candidate Mitt Romney, by a very small margin of 0.2%, or 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 9.2 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 Jr., 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) Emphasizing its Democratic shift even further, Joe Biden defeated Donald Trump by 17.1 points in Chester County in the 2020 election; Trump's percentage of votes was the lowest for any Republican since 1912. Such a major shift in the county was a major factor in Biden's success in flipping Pennsylvania back into the Democratic column. Although Trump gained back some ground in 2024 where he won back Pennsylvania; he still lost the county by 14 points to Kamala Harris despite matching his 2016 performance there. On November 8, 2017, Democrats made historic inroads in Chester County by winning their first county row office seats in history, picking up four row office seats. On November 5, 2019, Democrats swept the county row office seat elections and took a majority on the Board of Commissioners, both firsts in the county's history. In both the 2021 and 2023 elections, Democrats followed up with another sweep of the county row offices, along with retaining their majority on the Board of Commissioners.


Government


County Commissioners

Chester County is administered by a three-person Board of Commissioners who serve four-year terms. Elections take place in the odd-numbered years that precede U.S. presidential elections, with the next election scheduled for 2027. The commissioners have selective policy-making authority to provide certain local services and facilities on a county-wide basis. Accordingly, the commissioners are responsible for the management of the fiscal and administrative functions of the county. Currently, the Democrats hold a majority on the board, with Commissioners Josh Maxwell and Marian Moskowitz holding two of the three seats. County law requires the minority party to be represented with one seat, which is held by Eric Roe of the Republican Party. '':''

Public health


Opioid crisis

In both 2018 and 2019, deaths from drug overdoses in Chester County declined. Of the 104 drug overdoses recorded by the coroner, an estimated 77 percent involved the presence of fentanyl. One of the reasons for the decline in overdose deaths was "the saturation across the county of Naloxone, Narcan, the anti-opioid nasal spray that can revive someone suffering an overdose." In 2019, any resident of Chester County could obtain a free Narcan dose at community training events across the county.
