Reading this history

Each row is a distinct point-in-time snapshot of Maricopa County, not a revision of one file. Parcel counts move between vintages for real reasons — subdivision, consolidation, annexation, a re-survey — so a jump in the count is information rather than an error. This county's record here spans April 2017 to January 2023.

Archive vintages are released once they are old enough to be non-competitive; community vintages are contributed by users and published as soon as they pass verification. Both are free.
