Column Name: urb Span: 1790-2000 Units: Persons Format: Integer  Urban population generally comprises those persons residing in cities and other incorporated places having 2,500 inhabitants or more. This includes residents: of townships and other political subdivisions (not incorporated municipalities) with a total population of 10,000 or more and a population density of 1,000 or more per square mile; and of New Hampshire, Massachusetts, and Rhode Island towns (townships) containing a village or thickly settled area of 2,500 or more inhabitants and comprising, either by itself or when combined with other villages within the same town, more than 50 percent of the total population of the town. The urban definition used in 1930 (and later in 1940) was applied backward to all previous censuses, beginning with that of 1790.
