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: 35 per 100 working-age adults
Score 0: 58 per 100 working-age adults
Direction: Lower is better
Anchor: Fitted to the Thai provincial distribution

Goalposts of 35 and 58 are fitted to the observed DOPA 2025 distribution. The empirical band runs from 36.02 (Pathum Thani) to 56.83 (Tak), with median 42.05. The floor and ceiling sit approximately two points outside the observed band to absorb expected year-over-year movement without saturating either end. Tak sits 6.10 points above the next-worst province, consistent with the Mae Sot cross-border labor and refugee-camp registration anomaly documented in the methodology PDF.
