Women spend much more than men

A Business school publication says:

Women spend $4 trillion annually and account for 83% of U.S. consumer spending, which makes up two-thirds of the nation's gross national product, according to WomenCertified, a women's consumer advocacy and retail training organization headquartered in Hollywood, Fla., which also worked on the study.

The "Men Buy, Women Shop" study is based on a random, national sample of 1,250 shoppers who were asked about a recent shopping experience in telephone interviews conducted from October 20 to November 4, 2007. The sample was dominated, two to one, by females.
