Dorchester is a dissolved municipality and current neighborhood of Boston, Massachusetts, United States. It is named after the town of Dorchester in the English county of Dorset, from which Puritans emigrated and is today endearingly nicknamed "Dot" by its residents. Dorchester, including a large portion of today's Boston, was separately incorporated in 1630. It was still a primarily rural town and had a population of 12,000 when annexed to Boston in 1870. Railroad and streetcar lines brought rapid growth, increasing the population to 150,000 by 1920. It is now a large working class community with many African Americans, European Americans (and is still a center of Irish American immigration), Caribbean Americans, Latinos, and East and Southeast Asian Americans. Recently, there has been an influx of young professionals, gays and lesbians, and working artists to the neighborhood, adding to its diversity.
