Lemhi: Median household income 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 2023, which means all dollar values are in terms of 2023 dollars.
