  3. GDP Provinces

Updated June 2022. Last data available (predicted) for 2020.

Here are the GDP figures for 2020 (predicted values) in all the provinces of Thailand by region (latest data available at NESDC, published 2022). Numbers are Thai baht (real) in 2020.

There may be minor changes in these numbers in the following years. In a sense, recent published data always remain preliminary.

Compared to 2019, GDP by Region in 2020 changed as follows : Bangkok and Vicinity -8.4 % : Central Region -2.9 % ; Eastern Region -13 % ; Northern Region -5 % ; Northeastern Region +0.1 % ; Southern Region -12.7 % ; Western Region -4.6 % ; Thailand as a Country -7.7 %. The effect of the Covid-19 Pandemic with lockdowns and international tourism restrictions, was heartfelt.

Some observations : Of the 10 provinces with the lowest per capita income, 8 are located in the North Eastern Region. In 2020 Narathiwat in Southern Thailand was the poorest province. Mae Hong Son is a Northern province among the 10 poorest provinces.
The difference in between the regions, and in between the provinces in certain regions, are simply astounding.
The average GDP for the whole Kingdom of Thailand in 2020 was 224,962 Thai Baht. A decrease from 243,705 Thai Baht in 2019 (-7.7 $). FYI, NESDC states that were 69,509 million Thai inhabitants (-194,000 compared to 2019).
Population figures below are the ones estimated by NESDC for 2019. You may find slightly different numbers from other sources.

For 2020, the North Eastern Region is the only Thai region that saw a modest nominal growth (not inflation adjusted). Quite a few provinces therefore saw modest GDP growth.
