The index shows which countries have the most connected consumers, both overall and in terms of device detail – smartphone, tablet, mobile PC, desktop PC, wearables, smart TV, TV set-top box, video-game console, e-reader, connected car and smart home.

It also shows how connectivity has altered over the past five years.

Kevin Walsh, director of trends and forecasting at GfK, said: “As the technology markets mature, we are increasingly seeing that local country drivers are having a relatively bigger impact on connectivity growth, as opposed to global or regional trends – with consumers connecting in ever bigger numbers and different ways.”
