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: 50% urban pop
Score 0: 0% urban pop
Direction: Higher is better
Anchor: Fitted to the Thai provincial distribution

The v1.0 implementation uses a count-30km proxy: the number of major transit nodes (bus stations, rail, subway, ferry) within thirty kilometers of the urban centroid. Goalposts of 0 and 50 nodes are fitted to the Overpass-derived distribution across 2,157 Thai transit nodes. The dictionary specification is the population-weighted 400-meter-buffer measure, deferred to the Phase 2 production refit.

Live distribution: 5 of 77 provinces clip at the score-100 ceiling; 3 of 77 clip at the score-0 floor.

77 of 77 Thai provinces. Median score: 20. Each province's score is normalized 0–100 against fixed goalposts; a higher score is more favorable.

Reading the columns.Raw valuethe actual measurement in % urban pop.Scorenormalized 0–100 against fixed methodology goalposts (not a percentile). Higher is better.Why ties?5 provinces share the score-100 ceiling because their raw values meet or exceed the upper goalpost. 3 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.
