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: 0 events/yr
Score 0: 5,000 events/yr
Direction: Lower is better
Anchor: Fitted to the Thai provincial distribution

Goalposts of 0 and 5,000 cabinet-resolution flood-aid requests per 100,000 population are fitted to the observed DDPM 2024 single-year baseline. Highland and southeastern provinces typically record zero declared events; flood-prone central plain and northern lowland provinces in extreme years can reach the upper end of the band. Bangkok scores zero requests by design — urban drainage, not a declared disaster. Multi-year rolling-window scoring resumes once portal coverage accumulates.

Live distribution: 4 of 77 provinces clip at the score-100 ceiling ; 24 of 77 clip at the score-0 floor.

Reading the columns. Raw value the actual measurement in events/yr. Score normalized 0–100 against fixed methodology goalposts (not a percentile). Lower is better. Why ties? 4 provinces share the score-100 ceiling because their raw values meet or exceed the upper goalpost. 24 share the score-0 floor at the lower goalpost. Provinces beyond the goalposts aren't separated further — that's the trade-off for fixed, year-over-year comparable scoring instead of percentiles.
