Housing starts: inspect the monthly evidence
Follow each monthly figure to its notice, counting rule and official evidence.
A commencement notice records an intended start, not completed homes. Phase figures, whole-scheme figures and older estimates remain separate. Limited duplicate-signature checks do not establish national phase deduplication or distinct physical homes.
Source coverage through 2026-09-03. Evidence snapshot 2026-09-05T23:35:49+00:00. A closed calendar month does not establish complete national source coverage.
Month membership uses the validation date, then submitted date, then notified commencement date when the earlier field is absent. This preserves the existing published measure; a notified start can fall in another month.

2026-01: how the figures relate
| Measure / hold | Units |
|---|---|
| Source-stated phase units included | 1,757 |
| Older estimate or unconfirmed scope | 3,498 |
| Possible repeated phase: same project, start date and units | 122 |
| Stored official phase evidence could not confirm this value | 46 |
| No unit quantity stated | 0 |
| Whole-scheme figure; not counted as another phase | 1 |
| Current source-row sum | 5,424 |
| Preserved published figure | 5,424 |
| Unresolved published/source difference | 0 |
Record-level reconciliation
What explains the difference
5,424 preserved published units = 1,757 included phase units + 3,667 held source units + 0 unexplained published/source difference.
395 other held rows state no positive source quantity and add zero to this difference. The rule beside each record explains the hold; a whole-scheme hold is not a duplicate finding.
