Christianity Institution Anchors

Denominator traps
- 18.9% in 2020 ≠ 2026 measurement — no full census after 2020 as of Aug 2026.
- Census Catholic count ≠ archdiocesan all-age estimate — different populations and methods.
- NCCS ≠ all Protestant churches — many independent congregations exist outside council membership.
- No Christian statutory board — unlike MUIS under AMLA (islam and muis).
