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 9.3 hours old.

Of 187 datasets on this portal that advertise an update cadence, 74 (39.6%) were last updated longer ago than that cadence allows. The longest-running gap is 0.8 years.

Label bugs on finished datasets (6)

These datasets carry a recurring cadence label but their own titles state a closed coverage period, and their data stops where their titles say it stops. The data is not abandoned — the cadence label on it is simply wrong. Listed separately and excluded from the count above.
