The dependence of economies on various resources and the high level of societal inequality are well reflected in the economic indicators. For example, Gross National Income (GNI) per capita in 2015 ranged from US$1 070 to US$1 980 for Cambodia, Myanmar, Lao PDR and Viet Nam compared to over US$5 620 in Thailand. Out of this, only 13 percent is primary forest, 10 percent is planted forest and the remaining 77 percent is mostly degraded natural forest. Lao PDR had the highest forest area with 81 percent of the total land area of the country. In terms of actual forest area, Myanmar was highest with 29 million ha in 2015. There have been considerable changes in forest area of the GMS in the past 25 years.
