Notes: Income quartiles include both owners and renters. Median housing costs and household incomes are in constant 2016 dollars, adjusted for inflation using the CPI-U for All Items. Housing costs include cash rent and utilities. Indexed values are cumulative percent change.

Illustratively, the median monthly income for renters in the bottom income quartile fell by $50, dropping from $1,270 in 2001 to $1,220 in 2016 (a 4 percent decline). However, their median monthly housing costs increased by $70, rising from $690 to $760 (a 10 percent increase). This means that after paying for housing, renters in the bottom income quartile had less than $500 left to cover all other expenses (Figure 2), such as food, health care, insurance, transportation, and savings they could use for emergencies, retirement, education, repairs, or other needs.

While residual incomes for the lowest-quartile group are slightly higher than they were in recent years, they are still 18 percent less than in 2001, when these households had $600 in residual income (in inflation adjusted dollars). Moreover, 48 percent of households in the lowest-income quartile consist of more than one person, and 27 percent have at least one child present.
The situation is particularly bleak for renters in the lowest income quartile who spend more than 30 percent of income on housing. These cost-burdened renters had a residual income of only $360 per month in 2016, down 18 percent since 2001. In contrast, households in the same quartile that weren’t cost burdened had a residual income of $1,180 in 2016, down 6 percent since 2001. Part of this difference is due to the higher rates of cost burden among the very lowest-income renters within the quartile. Even so, cost burden reduces residual income.
As noted above, the story is quite different for higher-income renters. Monthly housing costs for renters in the top income quartile rose by $320, increasing from $1,360 to $1,680 (a 24 percent rise). However, their monthly incomes rose by $890, increasing from $10,440 to $11,330 (a 9 percent rise). As a result, these renters saw their residual incomes increase from $9,030 in 2001 to $9,660 per month in real terms.
