Smart Phone Adoption Correlates with Household Income, Except in China

Generally speaking, smart phone adoption is directly related to household income. But there are exceptions, such as the Chinese market, which "over indexes" for smart phone penetration. 


One suspects that subsequent generations of lower-cost smart phones and new retail plans are going to allow smart phone penetration rates to over index more like the Chinese market already does. 


In fact, you might argue that, despite lower per-capita monthly income, users in some "developing" markets already over index for smart phone penetration.
