Total household income and expenditures by income levels
The income and expenditure trends across different socioeconomic groups are more pronounced at the extremes of the income spectrum. Between 2004 and 2012, the total income of all households who earned more than $150,000 (7 percent of the U.S. population in 2012) increased by 9 percent, while the total income of all households who earned less than $30,000 (33 percent of the population in 2012) decreased by 1 percent.
During the same time period, each income group’s expenditure trends behaved similarly to their income trends. The total expenditures of all households earning more than $150,000 increased by 9 percent, while the total expenditures of all households earning less than $30,000 increased only by 1 percent.
