Saint Paul, Minnesota is noted for its neighborhoods. The city has been called "fifteen small towns with one mayor", owing to the neighborhood-based life of much of the city. Saint Paul is partially governed by not 15 but 17 City Districts. On Saint Paul's largely blue-collar East Side alone there are more than two dozen well-known, historically significant neighborhoods within four City Districts. District 4, for example, has three historic neighborhoods: Dayton's Bluff, Swede Hollow, and Mounds Park. The most populous districts, 2 and 5, have more than a dozen neighborhoods between them.
