Women are the primary shoppers, and fewer women shopped in 2011 than in 2007. On an average day in 2011, 46.6 percent of women aged 15 or older shopped in a store, by telephone, or online. This compares with a larger 48.2 percent of women who shopped for goods and services on an average day in 2007. Do the math and that's 2 million fewer shoppers per day than would have been in the marketplace if the percentage who shopped had remained the same.
To add insult to injury, the women who shopped on an average day in 2011 spent less time doing so--only 1.77 hours in 2011 versus 1.92 hours in 2007.
