What is in the file

Every field Hampden County publishes

Counties publish different things, so we measure what share of this county's parcels actually carry each field rather than promising all of them.

We have not measured per-field fill rates for Hampden County in the June 2026 release. The file ships with the same schema as every other county — what is missing is the measurement, not the columns. See the full field list.
