The last census was done about three decades ago and since then population estimates were based on forecasts derived from birth and death rates. The national census, completed this last April showed there were 51.4 million Myanmar nationals living within its borders. While that census included diplomats living abroad, it didn’t include students or migrants workers living outside of Myanmar. The Ministry of Immigration and Population said the final number could very well be 61 million but the final count won’t be known and publicized until May 2015.
There are a lot of Myanmar migrant workers in neighboring Thailand. In fact, Thailand and Malaysia are the top two countries for migrant workers from Myanmar distantly followed by India and Yunnan Province in China. Estimated at around 3 million for Thailand and Malaysia combined. Other estimates place the total Myanmar migrant population at around 5 million. It’s possible but unlikely that Myanmar has 10 million, about twice the population of Norway, of its citizens living abroad.
