Massachusetts's 3rd congressional district

Massachusetts's 3rd congressional district is a U.S. congressional district located in the eastern part of the Commonwealth of Massachusetts. The district, which has existed since the First Congress in 1789, currently encompasses a diverse swath of north-central Massachusetts, including the Merrimack Valley cities of Lawrence, Lowell, and Haverhill, as well as parts of the North Shore and central Massachusetts. It is represented by Democrat Lori Trahan, who has served since 2019.

Geography

Following the 2020 redistricting cycle, the district's boundaries were significantly reconfigured. It now stretches from the New Hampshire border in the north to the MetroWest region in the south, covering all or parts of Middlesex, Essex, and Worcester counties. Major population centers include the historic mill cities of Lowell and Lawrence along the Merrimack River, the city of Haverhill, and the towns of Concord, Acton, and Gardner. The district also includes parts of the North Shore, such as Beverly and Gloucester.

History

The district is one of the original eight districts created for Massachusetts following the ratification of the Constitution. Its early representatives were key figures in the Federalist Party, including Elbridge Gerry, a signer of the Declaration of Independence and later Vice President of the United States. Throughout the 19th and early 20th centuries, the district was a center for the Industrial Revolution, with its economy dominated by textile mills in cities like Lowell and Lawrence, which attracted waves of immigrants, including Irish, French-Canadian, and later Greek and Polish workers. The district was represented by John F. Kennedy from 1947 to 1953 before his election to the U.S. Senate and later the presidency. For much of the late 20th century, it was represented by Democrat Joseph D. Early.

List of Representatives

Notable representatives from the district include Founding Father Elbridge Gerry (1813–1815), Civil War-era Republican Charles R. Train (1855–1859), and John F. Kennedy (1947–1953). In the modern era, Democrat James Shannon served from 1979 to 1985 before an unsuccessful run for the Senate. He was followed by Chester G. Atkins (1985–1993) and Marty Meehan (1993–2007), who later became Chancellor of UMass Lowell. Niki Tsongas, widow of U.S. Senator Paul Tsongas, held the seat from a 2007 special election until her retirement in 2019. The current representative, Lori Trahan, won a crowded Democratic primary in 2018.

Election Results

The district is considered solidly Democratic. In the 2022 election, Lori Trahan defeated Republican Dean Tran with over 63% of the vote. This followed her victory in the 2020 election against Republican Catherine Ingrassia. The most competitive recent primary was the 2018 Democratic primary, where Trahan narrowly defeated Daniel Koh and Barbara L'Italien. The district's Cook Partisan Voting Index is D+14, indicating a strong Democratic lean.

Demographics

According to the 2020 U.S. Census, the district has a population of approximately 781,497. The racial and ethnic composition is 78.5% White, 7.5% Asian, 5.8% Black or African American, and 5.7% Hispanic or Latino. Cities like Lowell and Lawrence have significant Cambodian-American and Dominican-American communities, respectively. The district includes several institutions of higher education, including the University of Massachusetts Lowell and Middlesex Community College. The median household income is about $96,000, though there are considerable economic disparities between its affluent suburbs and its post-industrial urban centers.
