This article shows U.S. Census totals for Plymouth County, Massachusetts, broken down by municipality, from 1900 to 2010.
Like most areas of New England, Plymouth County is (and has been at all times since well before the 20th century) entirely divided into incorporated municipalities. There is no unincorporated territory. For any census, adding up the totals for each municipality should yield the county total.
There are two types of municipalities in Massachusetts, towns and cities. The tables below differentiate between towns and cities.
For more information on the New England municipal system, see New England town.

Notes
1970 Census
The Census Bureau made a number of revisions to 1970 census totals subsequent to their initial release. The 1970 total for the town of Bridgewater was originally reported as 11,829; and the town of West Bridgewater, 7,152. The totals were later revised to those shown in the list above. This was apparently done to correct an assignment error between the two towns; the collective population of the two towns is the same using either set of figures, so the county total was not affected.
