Median household income in the United States reached a new record high of $66,214 in September 2019, a 0.4% increase from Sentier Research's August 2019 estimate of $65,976.
The following chart shows the nominal (red) and inflation-adjusted (blue) trends for median household income in the United States from January 2000 through June 2019. The inflation-adjusted figures are presented in terms of constant September 2019 U.S. dollars.
The year-over-year growth rate for nominal median household income in the U.S. dipped slightly from August 2019's level of 5.3% to 5.1% in September 2019, which you can see as the red line in the following chart. After adjusting for inflation, that represents a change of just 0.1%, from 3.4% in August 2019 to 3.3% in September 2019, which is shown as the blue line in the following chart.
Analyst's Notes
The alternate methodology we developed for estimating median household income puts its level at $65,607 in September 2019, which is within 1% of Sentier Research's estimate for the month.
The continuing growth of median household income in the United States since January 2018 has been something to behold, where we would have to go back to January 2008 to see the next-highest inflation adjusted value recorded before January 2018. The first 18 years of the 21st Century represent quite a period of stagnation for the growth of median household income in the United States, particularly during this 10 year period!

In generating inflation-adjusted portion of the Median Household Income in the 21st Century chart and the corresponding year-over-year growth rate chart above, we've used the Consumer Price Index for All Urban Consumers (CPI-U) to adjust the nominal median household income estimates for inflation, so that they are expressed in terms of the U.S. dollars for the month for which we're reporting the newest income data.
