The map shows villages, but does it also show hamlets (i.e., unincorporated villages)?
The maps use a list of 290 villages across Long Island from the U.S. Census Bureau. This includes traditional, or “incorporated”, villages as well as all other communities that are sometimes referred to as hamlets or unincorporated villages. For example, the incorporated village of Roslyn is included as well as the unincorporated area of Roslyn Heights (in the Town of North Hempstead). The Census Bureau created boundaries for all of these areas that match the official boundaries of the incorporated villages as well as the generally accepted boundaries of the unincorporated areas.
