Pew Internet has released new data about American adults who use location-based services. “We find that 28% of adults use at least one of the key location-service opportunities that exist in mobile and social media spaces and by far the most popular is using mobile phones for maps, directions, or recommendations,” a spokesperson tells WebProNews. “Smartphone owners really stand out as a cohort that enjoy and use location services.”

5% of cell phone owners use their phones to check in to locations using geosocial services like Foursquare or Gowalla, according to the report. 12% of smartphone owners use these services on their phones.

Interestingly, 9% of Internet users set up social media services like Facebook, Twitter or LinkedIn so location is automatically added to their posts.

“Americans are not currently all that eager to share explicitly their location on social media sites, but they are taking advantage of their phones’ geolocation capabilities in other ways,” said Kathryn Zickuhr, Pew Internet Project research specialist and co-author of the report. “Smartphone owners are using their phones to get fast access to location-relevant information on-the-go.”

Smartphone owners, younger users and “non-whites” have higher-than-average rates of using location services, Pew says, sharing the following stats:

With the Deals space becoming much more integrated with the location-based service space, I would expect that more and more people in all groups will use location-based services.
