Goalposts

The 0-to-100 score for this indicator is normalized against fixed methodology goalposts. The values below define the band; click through to the methodology page for the framework that anchors them.

Score 100: 99 % households
Score 0: 70 % households
Direction: Higher is better
Anchor: Fitted to the Thai provincial distribution

Goalposts of 70 percent and 99 percent are provisional, pending the statbbi provincial-grain ingest in Phase 2. The band reflects the WHO/UNICEF JMP highest-tier service definition (piped water on premises) and the realistic spread across Thai provinces. Re-fit is scheduled for Phase 2 week 6 once the provincial source replaces the current regionally-imputed values. Provinces saturating at 99 percent share the score-100 ceiling by design.

Live distribution: 4 of 77 provinces clip at the score-100 ceiling .

Provinces beyond the goalposts aren't separated further — that's the trade-off for fixed, year-over-year comparable scoring instead of percentiles.
