The census numbers are presumably for full-time inhabitants; many of these houses are second homes and not primary residences, although the proportion of seasonal residents is decreasing.
The land for these communities is not privately owned, butleased from the state of New York through the year 2050. However, the residences on the property are owned. If the leases are not renewed at some point in the future, the owners will have to move the houses elsewhere, similar to what happened at High Hill Beach whenJones Beach State Park was created.
