Japan – perhaps surprisingly, given the country’s obsession with high-tech gadgets – also has a relatively low rate of smartphone ownership at 66%.

While smartphones are still beyond the reach of the poorest communities, rising living standards are creating huge new mobile markets across the developing world. China and India now have larger smartphone markets than the US, and Indonesia’s and Brazil’s are growing rapidly too.

But these gains are unevenly distributed. Pew research shows that in both advanced and developing nations, younger (under 35), educated people with higher incomes are more likely to own a smartphone.
In emerging economies with limited access to education, that gap becomes even wider. For example, in Nigeria 58% of adults with a secondary education use social media, compared with just 10% of those with less education.
