A Pew Research Center survey found that smartphone ownership is growing rapidly around the world, although not always equally, and social media use is somewhat less widespread, even as Internet use has grown in emerging economies. The file World Smartphone contains the level of smartphone ownership, measured as the percentage of adults polled who report owning a smartphone. The file World Social Media contains the level of social media networking, measured as the percentage of adults who use social media sites, as well as the GDP as purchasing power parity (PPP, current international $) per capita for each of 27 advanced and emerging countries.
