Every figure above is counted directly from the 17,737 Seneca County records in this site's copy of New York State's statewide tax parcel dataset — none of it is estimated or modelled. Assessment records are a snapshot of what each assessor filed, so an individual parcel can be out of date or incomplete.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.
