Median household income is the level of income at which half the population has lower incomes and half has higher incomes. Here, we provide information on real median household income, which means the data have been adjusted for inflation.
Note: The Consumer Price Index (CPI) is a measure of inflation. Here we adjusted dollar values by the CPI-U, which is the most commonly used CPI. Using the CPI to put dollar values in real terms makes it easier to see inflation-free change over time. Our base year is 2014, which means all dollar values are in terms of 2014 dollars.
