Field fill rates in New York
The share of residential parcels in New York on which each field is populated. Owner name, mailing address, lot size, assessed value and coordinates are filled on effectively every parcel nationally and are omitted. The structure fields are the ones that vary, because they come from county field cards that not every county publishes.

Denominator: parcels with a residential land use code. Fill rates on all parcels, including vacant land and commercial, are lower; on parcels with a building they are higher and the denominator varies by state. We use residential throughout so states compare.
What the New York file is used for
- Loading the state into a warehouse or product under a bulk license
- Owner and mailing-address appends for New York addresses
- Insurance underwriting inputs where the structure fields are filled, with the roof field supplemented from permit history because New York counties publish it on only 7.6% of parcels
- Purchase, refinance and new-homeowner triggers from the recorder side of the file
New York counties publish very few roof and construction codes. Year built and living area are well covered, and roof age for New York is best taken from permit history where a roofing permit exists.
