Here's the Nielsen synopsis of this chart:
Let me also point out that 25-54 Adults makes up two-thirds of all mobile internet usage.
Web visitors using a mobile device increased 34 percent year-over-year, from 42.5 million mobile Web visitors in July 2008 to 56.9 million in July 2009 according to The Nielsen Company. Overall, year-over-year growth among the 13-17 and 65+ age groups outpaced the growth of the total mobile Web audience, with a youth increase of 45 percent and seniors surging upwards 67 percent in July. While men continue to make up a larger portion of mobile Web users versus women, comprising 53 percent of the audience in July, the growth of female visitors outpaced the growth of male visitors during the month, with women increasing 43 percent YOY as compared to a 26 percent growth among men.
“As with other forms of Internet technology, more men were early-adopters of the mobile Web and still make up a slightly larger presence today,” commented Chris Quick, client services manager, mobile media. “Now that the technology is more mainstream, women are quickly embracing the benefits as ‘connected consumers,’ tapping the convenience of Web access on mobile phones to network, browse the latest shopping deals and get ideas for dinner, all while on the go.”
