SOURCES, VERSIONS & WHAT CHANGED
A clearer history for every download
The same source editions, rebuilt with traceable processing and fuller download documentation.
What changed on October 13?
All three customer downloads now come from our raw → staging → release pipelines. Each ZIP names its exact saved inputs and processing rules, includes a revision record, and accounts for excluded source rows where applicable. This is an ACD processing and packaging revision, available free to existing purchasers.
| Product | Delivered rows | Changes to the CSV |
|---|---|---|
| NAICS 2017 to 2022 Crosswalk | 1,150 | None: byte-identical to the previous sold CSV |
| NDC to ATC Crosswalk | 162,167 | None: byte-identical to the previous sold CSV |
| 2020 Census ZCTA to County Crosswalk | 46,960 | None: byte-identical to the previous sold CSV |
Sources and processing are separate
NAICS still connects 2017 to 2022 classifications. ZCTA still uses 2020 geography. The drug crosswalk still uses the retained October FDA/RxNorm/ATCPROD sources. No new publisher edition was fetched for this revision. The earlier March–October drug comparison remains mixed; this packaging revision does not change that history.
For existing customers
Your saved Stripe download page now serves the latest included revision. You do not need to pay again. For an older WordPress order or a lost link, contact support with your receipt. The dataset rows are identical, so this revision alone does not require rerunning your joins.
