Mobile marketers take note: working moms are a prime target for targeted marketing messages on the go, according to a new study by Scarborough Research.

In the study, Scarborough found that working moms are spending 21 percent more than the average mobile user on their monthly wireless bills. Moms are also 42 percent more likely to download mobile content than the average user.

?The working mom is among the country?s top spenders on wireless service,? said Howard Goldberg, senior vice president of agency services at Scarborough Research, New York. ?Further, they spend a good amount of time in their car.

"Combined, these characteristics suggest they are ripe for mobile marketing," he said.

Scarborough Research measures lifestyle and shopping patterns, media behaviors and demographics of American consumers. Scarborough is a joint venture between Arbitron Inc. and The Nielsen Company.

The study examined data based on the purchasing patterns and marketing appeal of women who work full-time and have one or more children at home.

Working moms are avid users of technology overall. Their homes are often well-equipped with technology such as HDTV, DVRs and iPods. They also tend to have their handset on them at all times.

?Not only do they currently own these technologies, but they are more likely than the average adult to plan upgrades as well,? Mr. Goldberg said. ?Clearly, the working mom represents a robust target market for technology products and stores.?

The working mom accounts for 9 percent of the adult population in the United States and 11 percent of all mobile users.

Scarborough found that mothers are more likely to use text messaging and downloading on their handset.

The study also found that working moms are 14 percent more likely than other mobile users to plan a wireless carrier switch during the next year.

Working moms are 9 percent more likely than the average adult to have driven 1,000 or more miles during the past month.

Mr. Goldberg said that the working mom is an interesting marketing target, especially for campaigns that have a mobile commerce tie-in, because she is a top-spender on clothing, groceries, home improvement products and accessories.

Because a working mother is on her mobile device so much, Mr. Goldberg said industries might benefit from not only targeting the working mom, but doing so via her mobile device.

?The working mom might be open to receiving content via her cell phone,? Mr. Goldberg said. ?This means that digital couponing could be a great way to introduce new products to her.

?And, she is not shy when it comes to technology adoption,? he said. ?So feel free to create all kinds of exciting downloads and applications for her mobile device.?
