Analyzing the monthly cell phone bills of roughly 65,000 mobile subscribers, Nielsen discovered that males age 13-17 took in 382 MB per month while their female counterparts used 266 MB. Overall, mobile data usage among teens of both sexes was up 256% over last year and growing at a rate faster than any other age group. See chart below. Click to enlarge.
