• Gross Provincial Product (GPP) per capita is a key indicator of the average economic output per person in each province and is widely used to compare regional economic performance across Thailand.
  
  
• Analysis of data for the period 2018–2024 indicates that Rayong consistently recorded the highest GPP per capita, driven by its concentration of petrochemical industries, oil refineries, and automotive manufacturing, which form the core of Thailand's Eastern Economic Corridor (EEC). Bangkok ranked second, reflecting its role as the country's principal centre for business, finance, trade, and services.
  
  
• Provinces with well-developed industrial bases and major economic zones, including Chon Buri, Phra Nakhon Si Ayutthaya, Samut Sakhon, and Pathum Thani, generally recorded medium to high levels of GPP per capita. In contrast, many provinces in the Northeastern region and parts of Northern Thailand, where economic activity is more heavily dependent on agriculture, exhibited relatively lower levels of GPP per capita.
  
  
• These findings highlight the considerable variation in economic performance across provinces, reflecting differences in industrial structure, investment, and productivity. GPP per capita serves as a valuable indicator for regional economic analysis and provides an important evidence base for investment planning, business strategy, and the formulation of regional development policies.
