Each row is a distinct point-in-time snapshot of Madison 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 September 2020 to August 2024.
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.
