Historical U.S. Census Totals for Washington County, Rhode Island
This article shows U.S. Census totals for Washington County, Rhode Island, broken down by municipality, from 1900 to 2000.
Like most areas of New England, Washington 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 Rhode Island, towns and cities. The tables in the New England Historical U.S. Census Totals series differentiate between towns and cities; however, there have never been any cities in Washington County. Like some of the other New England states, Rhode Island once also had "districts", which were essentially small and/or recently incorporated town-like communities that did not have the full privileges of a town. The present-day town of Narragansett was a district early in the 20th century.
