With the PC market currently circling the drain, it should come as no surprise to see global mobile web traffic on the rise. But new numbers from Statista find mobile phones accounting for 17.4 percent of web traffic worldwide in July 2013, a surprisingly big 57-percent jump from the 11.1 percent Statista recorded for July 2012.

The statistics company measured page views originating from mobile devices—excluding tablets—to come up with its data. Broken up by continental regions, South America represents the low end of the spectrum in the study with 6.8 percent of its traffic coming from mobile, up 3.2 percent annually. At the high end, Asia saw a whopping 26.6 percent of its web traffic come from mobile, compared to 18.8 percent a year ago.

The biggest leap in volume arrived in Africa, where mobile phone traffic hit 23.7 percent, a more than 100 percent increase over the 11.3 percent recorded a year prior. North America meanwhile saw 15.2 percent of its web traffic for July come from mobile, up from 9.4 percent a year ago.

The percentages in Statista’s report fall in line with Cisco’s projected mobile data growth explosion. In its Visual Networking Index Global Mobile Data Traffic Forecast, Cisco envisioned mobile data growing 13-fold by 2017 to 11.2 exabytes per month.
