The Groundwork Data Vault: source manifest and code maps (version 2026-11-03)

Dated, fingerprinted copies of the public U.S. Census Bureau and Bureau of Labor Statistics county files behind Groundwork Business Advisory’s county tools. This record publishes the manifest of 2,303 vaulted files (203 Census and BLS files plus 2,100 files behind the federal Opportunity Zone layer) (source web address, size, SHA-256 fingerprint and fetch date for each), the row counts of the normalized county panel, the NAICS 2012-2017-2022 code map with a list of 919 industries whose meaning did not change, and a table of which geography Connecticut uses in each source. The raw files are public and are not included; the manifest lets anyone check a copy. Home page: https://groundworkbusinessadvisory.com/data-vault/
