Geographic-scope notice: Rockland is not a separately-incorporated place in the U.S. Census Bureau's Place geography – it is either a neighborhood within a larger municipality (in Plymouth County) or a town-class subdivision in a state where the Census reports demographics at the town rather than place level. To avoid presenting county-level aggregates as city-level data, this page does not show synthetic Census or health figures for Rockland. For the surrounding county aggregates, see the Massachusetts state directory.
