Affluence in the United States

Affluence refers to an individual's or household's economical and financial advantage in comparison to a given reference group.

Affluence as a metric

Affluence in the United States has been attributed in many cases to inherited wealth amounting to "a substantial head start": in September 2012, the Institute for Policy Studies found that over 60 percent of the Forbes richest 400 Americans had grown up with substantial privilege.

Income is commonly used to measure affluence, although this is a relative indicator: an upper middle class person with a personal income of $77,500 annually and a billionaire may both be referred to as affluent, depending on reference groups. An average American with a median income of $32,000 ($39,000 for those employed full-time between the ages of 25 and 64) when used as a reference group would justify the personal income in the tenth percentile of $77,500 being described as affluent, but if this earner were compared to an executive of a Fortune 500 company, then the description would not apply. Accordingly, marketing firms and investment houses classify those with household incomes exceeding $75,000 as mass affluent, while the threshold upper class is most commonly defined as the top 1% with household incomes commonly exceeding $525,000 annually.
