Although the incorporated city of Lake Worth Beach is small geographically, as is common in Palm Beach County, a large unincorporated urbanized area with a Lake Worth postal address lies to the west of the city, and includes the census-designated place of Lake Worth Corridor. It also includes western neighborhoods and communities such as The Fountains, Lago Lucerne, Lake Osborne Estates, Melaleuca Lane Corridor, and Palm Beach National. The total population of both incorporated and unincorporated Lake Worth was estimated by the 2006 Census to be 190,377.
