Coverage is a district-level comparison of Chonburi province, where Pattaya lies (Pattaya City is inside Bang Lamung district). The 11 districts are administrative areas, not hotel neighbourhoods or Pattaya streets.
Road deaths 2022-2025 (Buddhist Era 2565-2568, all 12 months each year) by district from the Chonburi provincial dashboard dataset (source: Chonburi Disaster Prevention and Mitigation Office annual reports). Yearly province totals vary (2022 695, 2023 1614, 2024 953, 2025 633), so definitions may differ between years; only relative district rates over the pooled four years are used.
Denominator: WorldPop R2025A constrained 2024 population (100 m model estimate, includes non-registered residents) summed inside each district; four-year person-years. Rates per 100,000 per year are shrunk toward the province rate with a Gamma-Poisson prior of 10 deaths to damp small-number districts such as Ko Si Chang (1 death).
Only mobility varies locally; the citywide estimate and other dimensions use Thailand national research priors. Tourist traffic exposure, crash location versus residence, and seasonal visitors are not separated.
