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 plateau: 80 – 800persons/km²
Score 0 floors: ≤ 15 or ≥ 4,000persons/km²
Direction: Mid-range is best (parabolic curve)
Anchor: Fitted to the Thai provincial distribution

Density scoring is parabolic, not monotonic: too sparse limits amenity access and too dense imposes claustrophobia. The score-zero floors sit at 15 and 4,000 persons per square kilometer; the score-100 plateau runs from 80 to 800. Mae Hong Son at 22.6 scores 11.7 (rural-extreme); Bangkok at 3,467 scores 16.7 (past-optimum); mid-density provinces such as Krabi (~85) and Khon Kaen (~110) reach the plateau and score 100.

Live distribution: 59 of 77 provinces clip at the score-100 ceiling.

Reading the columns.Raw valuethe actual measurement in persons/km².Scorenormalized 0–100 against fixed methodology goalposts (not a percentile). Mid-range is best (parabolic curve).Why ties?59 provinces share the score-100 ceiling because their raw values meet or exceed the upper goalpost. Provinces beyond the goalposts aren't separated further — that's the trade-off for fixed, year-over-year comparable scoring instead of percentiles.
