Not all, but the customer base is disporportionally below-median-income. Over 20% of WMT customers in the U.S. don't have any bank accounts - compared with 13% for the general population. Liza's away now, or she could give a better picture than I, but they're still heavily skewed towards nonmetropolitan areas.
