Data Quality Report

Most data products publish their strengths. Reference bodies publish their defect statistics — openly and on a schedule — because a source you can audit is worth more than a source that claims perfection. This is SkyMind's first periodic quality report: every number below is computed from the live database at build time (as of 16 July 2026), nothing is rounded, and the uncomfortable rows stay in. Next edition: October 2026.

The database, counted live

Counted at build time from the live warehouse, one family at a time. Unit counts exclude the 7 Belarus regions retained in the reference dimension but removed from the product in June 2026 (license and sanctions review).

Every change, on the record

Since 13 July 2026 an append-only, trigger-enforced revision ledger records every insert, update and delete on any published value — loaders cannot bypass it. Recorded so far: 178 value changes (2026-07-13 … 2026-07-15).

Disputes & corrections

Anyone can dispute a published number; every dispute is reviewed and its resolution published. Status at build time: 0 disputes filed since the channel opened (16 July 2026) — 0 open, 0 resolved.

Defects we have published about ourselves

The corrections that shaped this database. None of these were silent fixes — each is documented, and the current pipeline exists largely because of them.

Known limitations, stated plainly

• Ukraine: regional series end in 2021 — the war suspended sub-national statistics. We show the history and say so, rather than extrapolate.
• European composite uses 2 axes (economic + demographic). The social axis is excluded for EU-schema countries because its only cross-country metric (tourism nights) begins in 2020 and would break comparability across years. Core-family countries keep 3 axes.
• Gulf chart typography is English: our chart renderer cannot yet shape Arabic RTL text; Arabic-first chart output is an open item.
• UAE: 231 official communities carry the composite; 109 well-known informal district names (Marina, Downtown …) are shown on the map but deliberately unscored — they have no official statistics.
• Mixed granularity in Saudi Arabia: 13 regions carry full composites; 38 governorates carry partial metric sets and no composite.
• Small-language region pages (Estonian, Latvian, Macedonian …) are best-effort translations pending native review.
• Upstream traps are catalogued, not assumed away: coverage holes, carry-forward years, rounding ties, unit mislabels and impossible values are tracked in an internal trap registry (9 classes) and checked before every publication — see the pipeline replay.

Data currency

Per-source freshness — what year each resource is current through and when the next upstream release is expected. SkyMind does not control agency publication schedules.
