Insights on the iPhone Mom
by Noa Gafni
Sunday, December 20, 2009

Greystripe's Q3 Mobile Advertising Insights Report provides the most recent data about a little studied demographic: the iPhone mom. According to Greystripe, "the iPhone has greatly altered the mobile application user demographic" whereas in the past mothers were not "a group that advertisers could readily reach through mobile applications." Currently, however, "the iPhone Mom is now a common and active mobile application user. This demographic is particularly interesting to advertisers as iPhone Moms are the dominant purchasing decision makers for households with several consumers."

So who are the iPhone Moms? 62% are between the ages of 25-44, with an additional 24% between 45-54 years old. They are well educated: 30% have a Bachelor's degree, 4% have attended at least some graduate school, and an additional 16% have an MA degree or higher. iPhone moms are varied in the number of children they have and the ages of their children, although they tend to skew older.

Moms download a variety of applications. A full 94% of iPhone moms download games and entertainment apps, 76% download music apps, and 50% use social networking apps. They find out about apps through different sources, including looking at the top apps (67%), checking out the featured apps in the App Store (65%), and through friends (64%).

In addition to applications, 87% of moms use the device for email, 81% use the maps, 68% use the calendar, and 58% for social networking. 79% use their phone for activities related to shopping. The most common shopping related activity? Using their iPhone to locate the nearest store.
