Got a cell phone? You're probably online with it, says Pew

Pew reporting:
If you're trying to engage your community with digital news and information: they're on their phones. You should be there, too. This week, a new report from Pew Internet underscores the importance of putting mobile first in engaging almost any community.
Pew found that nearly two thirds of U.S. adults now use their cell phone to go online -- nearly double the proportion since 2009. Furthermore, one in five cell phone owners report that their cell phone is their primary access to the internet.
…And that's in reference to all kinds of cell phones, including feature phones (many of which support e-mail and web access). When focusing only on the 56% of U.S. adults who currently own a smartphone, the vast majority (93%) of smartphone owners use their phone to go online.
Pew defines "cell internet users" as anyone who uses their cell phone to access the internet or use e-mail. Pew found that one third of all cell internet users rely mostly on their phone to access the internet (as opposed to other devices like a desktop, laptop, or tablet computer).
Pew did not specify whether "accessing the internet" means only accessing websites and e-mail, or whether it also includes using apps that deliver information transmitted via the internet -- something that many apps do, especially for news and information.
Some demographic highlights about cell internet users from the Pew report:
