Every figure above is counted directly from the 423,430 Nassau County records in this site's copy of New York State's statewide tax parcel dataset — none of it is estimated or modelled. Nassau County's records in this dataset do not populate year built and finished living area, so they are left out rather than guessed. Assessment records are a snapshot of what each assessor filed, so an individual parcel can be out of date or incomplete. Nothing here is a title search or a legal description of a property.
