But they're a lot easier to group together than any other races. Like most other races, they have similar cultural values (parents/family is the most important thing, education is a close second), they have some shared experience (India was under British control for a period of time, China and Southeast Asia were both at least under European influence, if not control (See: Vietnam)).

So how would you group them? People from the Middle East at least share a common religion, even with many North Africans, and are arguably a significant subgroup of "Asians" overall, but the average Indian is a lot closer to the average East Asian individual in general. Buddhist ideas are stemmed from Indian religious ideas, and plenty of shared cultural beliefs exist.

Why do we need to group them? It would be a very different society if group membership were opt-in similar to Circles in Google+. Reminds me of the society in Doctorow’s Down and Out in the Magic Kingdom. Not that this would be a better society. But definitely would have different failure modes and novel solutions.
