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 .

Coverage

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

Reading the columns. Raw value the actual measurement in persons/km². Score normalized 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.
