* Mobile Net users: 7% of adults who go online with their cellphone use a location-based service.
* Younger adults: 8% of 18-to-29-year-olds use these services, significantly more than other age groups.
* Ethnicity: 10% of online Hispanics use these services, compared to 5% of blacks and 3% of whites.
* Gender: 6% of online men and 3% of online women use location-based services.
