Imagine if Soviet Union was still together!

I think it would take a little bit off China, but the picture would be generally the same. It demonstrates, the general trend that big chunk of Russia will be populated by chinese one way or the other.

I'd like to see a map like this for number of people or percent of population earning between the median and average wage for the country.  I'm thinking this would be a quick way to create a disparity of income map by country.
