Are you reading this on your phone?

Your audience is increasingly going mobile.

A new survey by the Pew Research Center’s Internet & American Life Project finds that nearly two-thirds (63%) of cell phone owners now use their phone to go online. Because 91% of all Americans now own a cell phone, this means that 57% of all American adults are cell internet users. The proportion of cell owners who use their phone to go online has doubled since 2009.

Additionally, one third of these cell internet users (34%) mostly use their phone to access the internet, as opposed to other devices like a desktop, laptop, or tablet computer. They account for 21% of the total cell owner population. Young adults, non-whites, and those with relatively low income and education levels are particularly likely to be cell-mostly internet users.
