Suffolk County (/ˈsʌfək/ SUF-ək) is located in the Commonwealth of Massachusetts, in the United States. As of the 2020 census, the population was 797,936,[1] making it the fourth-most populous county in Massachusetts.[2] The county comprises the cities of Boston, Chelsea, and Revere, and the town of Winthrop.[3] The traditional county seat is Boston, the state capital and the largest city in Massachusetts.[4] The county government was abolished in 1999, resulting in Suffolk County now functioning only as an administrative subdivision of state government and a set of communities grouped together for some statistical purposes. Suffolk County is located at the core of the Boston-Cambridge-Newton, MA-NH Metropolitan Statistical Area as well as the greater Boston-Worcester-Providence, MA-RI-NH-CT Combined Statistical Area.
