I really dislike articles that generalize based on race, religion, sex, etc. It's inappropriate and says nothing about individuals (all of whom are unique).

When you're researching a large nation with more than a billion people, you'll find a lot of people who have degrees and a lot of people who do not and a lot of people who like chewing gum and (again) a lot of people who do not.

The only thing the results should tell you is that there are a lot of people there. They say nothing about the average individual.
