The worldwide tablet audience has a few more years of double-digit growth in store, according to eMarketer’s latest forecast for usage of the devices around the globe. We estimate that this year, 1.00 billion people will use a tablet at least monthly, including people who own their own tablet as well as those who use devices belonging to a friend, family member or other source.

eMarketer previously forecast a worldwide tablet population of 1.06 billion for this year, and has revised current figures downward. However, we expect growth this year and in the near future to be faster than our previous forecast predicted.
Asia-Pacific will be home to the largest number of tablet users in the world, with 458.7 million expected this year. The region will pass the half-billion mark in 2016 and boast more than three-quarters of a billion tablet users by 2019, the end of our forecast period.
