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: 70%
Score 0: 5%
Direction: Higher is better
Anchor: Fitted to the Thai provincial distribution

Goalposts of 5 percent and 70 percent are fitted to the observed RFD provincial distribution. Median provincial forest cover sits at 17.6 percent and the 90th percentile at 57.5 percent, so the 5/70 band spreads the realistic Thai distribution across the full scoring range. The same goalpost pair is used for the Hansen tree-canopy companion indicator so audiences can compare the two scores directly. Divergence between the two is informative, not noise.

Live distribution: 2 of 77 provinces clip at the score-100 ceiling; 13 of 77 clip at the score-0 floor.
