Estimated average time (number of hours per day) spent online by individuals between 16 and 64 years of age [27]. Times vary, as shown here, between countries.

In the USA in 2017, this number was estimated to amount to two hours and 20 min per day for children between zero and two years of age and four hours and 30 min for kids between eight and 12 years of age [28,29].
