Build coverage when the evidence arrives.

The release workflow

1. Register the original publication, table code, release date, coverage and correction notices.
2. Retain the source document and checksum; extract exact values without inventing missing places or categories.
3. Validate totals, sex/age/residence components and rounding. Keep unavailable and not-stated values separate.
4. Review definitions and year-specific geographic codes; use a documented crosswalk only where genuinely compatible.
5. Publish source-labelled tables, profiles, accessible charts and downloads as a distinct Census 2027 edition.
6. Record revisions and refresh related comparisons from the same canonical data record.

2027 intake: Houselisting published aggregate tables on dwelling quality, water, sanitation, energy and assets.

What readers should get

• Water/sanitation/energy dashboards
• Housing tenure and condition
• Amenities linked to population context without pretending it is current census data

Checks before publishing

• Households and population are different denominators
• Exclude institutions where source does
• Do not confuse HH-14 references in older material with catalogue's HL-14 series
• Verify district files individually and don't treat Nawada example as national
• Assets can overlap and their shares need not total 100

Place coverage and cost

Expand villages, subdistricts and wards through verified official files and bounded search, keeping codes and source notes. Nationwide micro-area profiles are still a gap. Pages and downloads will remain static where practical; no paid per-visit AI or database is part of this plan.

Keep the historical 2011 atlas and original Blogger articles intact. Future comparison pages must explain changes in boundaries, categories and measurement. No release date for a future results table is promised.
