Plymouth County, Massachusetts, is defined by its coastal character and historical significance, notably the town of Plymouth, where the Pilgrims landed in 1620. Located south of Boston, many towns in the county offer convenient commuter rail and bus services to the city, typically around a 40-mile drive. The region blends quaint New England charm with access to natural beauty, including miles of coastline, numerous ponds, and extensive parklands like Myles Standish State Forest. These areas provide opportunities for hiking, biking, swimming, kayaking, and whale watching. Duxbury and Hingham are among the notable towns, recognized for their strong communities and highly-regarded public schools.
Life in Plymouth County often appeals to families and those seeking a coastal lifestyle with a connection to history. The economy, historically reliant on tourism and residential development, is undergoing a shift. While the county has benefited from residential growth, there is a recognized need to diversify the tax base beyond housing. Efforts are underway to attract new businesses and foster innovation, particularly in emerging technologies and the marine economy, also known as the "blue economy." This includes exploring aquaculture and leveraging the county's coastal assets.
