When people talk about “the rich,” they might often think of millionaires and billionaires, but this thinking would not be completely accurate. People may assume that being in the top 10 percent makes you incredibly rich—and at one time this may have been the case—but incomes in the United States are rising (even after controlling for inflation). If one considers “the rich” to be those within the top 10 percent of income earners, then an overall increase in incomes would cause the level of income required to be one of “rich” to rise as well. Data provided by the IRS and Census confirms this.

According to the IRS, for individual tax filers in 2001 who didn’t list any dependents, an income of more than $130,305 was sufficient to be among the top 10 percent. By 2015 this threshold had risen to $139,806, a nearly $10,000 increase.

A different set of IRS data for all individual returns with a positive adjusted gross income shows that the floor for the top 10 percent of incomes rose nearly $20,000 over 23 years. In 1986 an income of $106,549 was sufficient to be among the “rich.” By 2009 this had grown to $125,435. This pattern is not limited to individual incomes. According to the Census Bureau, there has been an approximately $76,000 increase in the income floor for the top 10 percent of households as well, though this increase has taken place over a much longer period. In 1967 the cutoff for “rich” households was only $94,529. By 2016 this had risen to $170,536.
