NEW YORK - A new study by Yahoo and Nielsen found that approximately 34 million Americans access restaurant and dining information with their mobile devices, Marketing Daily reports.

Of those 34 million, more than half are between the ages of 13 and 34. The group trended toward annual incomes of $87,000, with more than half married and 41 percent with children. More than half (58 percent) said they lived in the suburbs.

In searching for dining data, 82 percent used the search function, while 68 percent used their mobile browser and 17 percent an app. Around a third (34 percent) recalled a mobile dining ad and most of those (77 percent) "always" or "sometimes" viewed the ad.

Nearly half (49 percent) surfed for casual dining locations, such as Applebee??s, Chili??s and Olive Garden, while 30 percent browsed for fast-food chains, such as Subway and McDonald??s. Less than a fourth (23 percent) wanted data on fine-dining establishments, such as McCormick & Schmick and Morton??s Steakhouse.

"The data shows an evolution," said Edwin Wong, Yahoo??s director of market research. "Before, it was the early adopters and 'foodies?? who were driving toward fine dining and niche dining experiences, with users accessing sites like Yelp.com. As mobile usage has grown, we're seeing more interest in mass market dining info. That's a trend we expect to continue."

"When on the go, people often make dining decisions spontaneously," according to the Yahoo/Nielsen study. "They do a little research, usually taking no more than a few minutes to come to a decision."
