National Government Open-Data Freshness Index

A dated, independently recomputable record of public datasets that advertise an update cadence they are not currently meeting.

What this record is. Each row compares the update cadence a dataset advertises in its own portal metadata against the last update time that same portal reports. Nothing here is a claim of wrongdoing, and nothing here is scraped from a third party — every figure is recomputable from the portal's own public API in seconds using the link in the row. Datasets whose own titles say they are historical or cover a closed period are excluded from the headline and listed separately.
Method: Socrata catalog API; advertised Update-Frequency vs measured data_updated_at; frozen >3x the advertised budget; self-labeled historical excluded; bounded-period datasets reported separately as label bugs, not abandoned feeds
Producer: core/govdata_national_merge.cjs · recompute boundary 2026-10-28T14:30:00.000Z · record is 8.4 hours old.

2,187 datasets across 44 portals currently advertise an update cadence their own metadata shows they are not meeting. 48 of 90 portals audited could be graded at all.

Portals that publish no freshness claim at all (42)

These are not clean results. These portals expose no update-frequency field, so no freshness claim of theirs can be checked — by us or by anyone consuming their data. Absence of a claim is reported as absence, never as a pass.
