Claritas Income Producing Assets Indicators estimates the liquid assets of a household based on responses to the Claritas Financial Track survey of financial behaviors—the largest financial survey in the industry—for which Claritas has actual dollar measures from each survey respondent. From the survey base, information for nearly 150,000 households (using a rolling three years of quarterly surveys) is used to construct balance information for a variety of financial products and services.
Strongly correlated to age and income, the Claritas Income Producing Assets Indicators model measures liquid wealth such as cash; checking accounts; savings products such as savings accounts; money market accounts and CDs; investment products such as stock and mutual funds; retirement accounts; and other asset classes that are relatively easy to redeem and move—and for which marketers can readily compete. The model classifies all U.S. households into one of eleven IPA ranges, with values ranging from less than $25,000 to over $3 million.
