Some 17.6 percent of U.S. smart phone users accessed at least one "check-in"-oriented mobile platform during the month of March, 2011 representing 7.1 percent of the nation's entire mobile population, according to comScore.

Location-based service users are more likely to interact with other forms of mobile media and content than non LBS-using smart phone owners. They demonstrated a higher propensity for consuming news content through their handsets, as well as accessing restaurant information and online retail sites, based on data collected in the three-month period ending March 31, 2011

LBS users were also more likely to own a tablet, and a higher percentage recalled seeing ads on their mobile devices. In terms of demographics, 13 to 34 year olds accounted for the majority of users for location services, representing 66.8 percent of users.
