What is the deal with the Vietnamese hairdressers? From the charts, it seems that over 10% of Vietnamese workers are hairdressers (or "other grooming services"), and they are more numerous than the hairdressers of all other nations, combined.

Good question. And we can ask it for other categories, too. There are several in which one country dominates the field.

3. Computer software developers: India

8. Nurses: Philippines

14. Cooks: Mexico

16. Hairdressers: Vietnam

19. Gardeners: Mexico

20. Janitors: Mexico

24. Farm laborers: Mexico

Farm laborers coming from mexico makes sense. But what about nurses from the Philippines?

English is one of the two official languages in the Philippines, and they also have a high standard of education. That combination is perfect for nurses.
