Again, it is important to note how Thailand and Myanmar define their primary forests as explained above. Myanmar has the greatest total remaining forest area but has also seen the greatest forest loss among the Mekong countries. Most of the decrease has been in the other naturally regenerated forests, with a much smaller portion of deforestation being reported in the remaining primary forests. The total population in 2015 was 15.6 million - it increased by approximately 73 percent during 1990 to 2015, with a 62 percent increase in rural population and a 130 percent increase in urban population.
