These figures have been taken from using data from Indonesian provinces, Malaysia states, Philippine, Thai, and Vietnam regions.
Gross domestic product (GDP) is the market value of all final goods and services from a nation in a given year.
[8] Nominal GDP does not take into account differences in the cost of living in different countries, and the results can vary greatly from one year to another based on fluctuations in the exchange rates of the country's currency.
GDP comparisons using PPP take into account the relative cost of local goods, services and inflation rates of the country, rather than using international market exchange rates, which may distort the real differences in per capita income.
[9] PPP is often used to gauge global poverty thresholds and is used by the United Nations in constructing the human development index.
