That's crazy. The google source says 34.66 million in 2016. Wikipedia gives 29.72 million for 2017. The difference in between is HUGE. No idea why and what is correct. For quiz purposes great as long as there's one source for it all.

So even though there appears to be no land border between them, Lake Tanganyika is considered a true border for DRC and Tanzania? I have always thought "border" to mean land border.

If you discounted lakes you'd probably have to throw out borders across rivers, too, and that would eliminate a lot of bordering countries.

True. I guess there aren't many examples of borders like this that are exclusively lakes rather than rivers. I suppose if I asked myself "what country IS the border in that area?", there wouldn't be any other answer.

On the cited source ( https://en.wikipedia.org/wiki/List_of_countries_and_dependencies_by_population ) Indonesia is 4th and Malaysia 41st. (41+4)/2 = 22.5, putting it just off this list.
