Since many of the facts and figures in this Viet Nam update are outdated, below is my (more up-to-date) information, where necessary and available, including sources and some comments.
Youth Population Breakdown (2015): This up-to-date information is from the CIA World Factbook for Viet Nam.
Adjusted National PCI (2014): The most up-to-date information from the World Bank is $2,111.10 (for 2015).
GDP PPP PCI (2014): A more recent figure, which reflects how rapidly the economy is growing and therefore the ability to pay for big ticket items like overseas study, is $6,000 (2015), from the CIA World Factbook – Viet Nam
Number of Internationally Mobile Tertiary Students (2013): There is more up-to-date information. For example, there are nearly 110,000 Vietnamese students in the top 5 host countries alone, including Japan, the USA, Australia, China, and Singapore – in descending order. Even in 2013, there were an estimated 125,000 Vietnamese studying overseas in 49 countries and territories, and that was a low estimate, in my opinion.
Top 10 destinations (2013): The numbers are old. The most recent top ten list would look more like this: Japan, USA, Australia, China, Singapore, the UK, France, Russia, Germany, and Canada.
Student weeks in ELT (2014): Isn’t there anything more up-to-date? This market segment is changing rapidly. As of 3/16, 11.9% of all Vietnamese students (3458) in the US were enrolled in “language training” programs.
K-12 students abroad (2013): The numbers are old. For examples, there were 3715 Vietnamese students enrolled in US secondary (3537/12.2% of 29101) and primary (178/.6%) school as of March 2016 and 1731 in Australian schools as of May 2016. That’s a total of 5442 in those two countries alone.
K-12 students by destination (2013): Probably similar three years later.
Government-Certified Education Agencies: This is based on the number of Vietnamese students these companies send overseas. The data are self-reported, which casts doubt on their accuracy. One additional point is that education agents are no longer certified in Viet Nam as of 1 July 2016. The Ministry of Education and Training rescinded the policy approved in 2013 by the Prime Minister.
Number of Domestic Higher Education Providers (2012/13): This figure is correct, more or less.
Percentage of Vietnamese Students Abroad Who Are Self-Funded: I don’t have up-to-date information but suspect this is still correct, based on my experience and from what I’ve read. This is the figure used by Viet Nam’s Ministry of Finance.
