Each row is a distinct point-in-time snapshot of Johnson 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 June 2021 to May 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.
