Survey of Buying PowerThese include effective buying income (EBI, a measure of disposable income) and the buying power index (BPI, a measure of spending power based on EBI and additional factors). Demographics are broken out by age, race, city, county and state. The data will be of particular interest to companies running consumer marketing promotions, although any sizable incentive program may be able to use the demographic data to its advantage.
The Survey of Buying Power is a compendium of nationwide consumer data published annually by the magazine "Sales & Marketing Management".
