In Indonesia, as elsewhere, there is a direct and linear correlation between smartphone use and age. Some 70 percent of Indonesians under the age of 25 use a smartphone. In the age cohort 25 to 34, about 46 percent of Indonesians use smartphones.
In the 35 to 44 age cohort, some 38 percent of Indonesians use smartphones. Indonesians 45 to 54 use smartphones at a 27 percent rate. In the 55 or older group, just 13 percent use smartphones.
