Russia Stats (World Bank)
Interesting comparison of GNI (Atlas Method) and GDP (PPP). Unfortunately this comparison is for 2001, but things haven't changed much since then.
Comparison of per capita GNI (GDP) [Atlas Method vs. PPP]
I cannot possibly imagine how Russia's PPP GDP/capita has been adjusted to be equal to Mexico's, when Moscow is one of the world's most expensive cities. I think someone is cooking the numbers.
The Real per capita GDP of Mexico is higher than that of Russia.
