Asia, even though it has around 60% of the world's population, it only has around one third of the languages spoken in the world, so automatically there's a big disproportion between the number of population and number of languages, thus giving it a smaller percentage of languages dying out.
- <em>Keeping the tradition;</em>
Lots of Asian nations are not very willing to let their traditional language to die out and continue to speak it. Apart from the traditional point of view, another reason is that Asia has global economic powers, so learning languages like the English or Spanish are not of great benefit in general, so the pressure is much lesser.
