The following chart shows the nominal (red) and inflation-adjusted (blue) trends for median household income in the United States from January 2000 through March 2019. The inflation-adjusted figures are presented in terms of constant March 2019 U.S. dollars.
Year over year, median household income in the U.S. has risen by 3.6%, but while positive, the rate at which it is rising continues to decelerate, having peaked in October 2018.
The monthly data reported by Sentier Research is consistent with the U.S. economy having hit a speed bump during the last several months, after having seen remarkably steady and robust growth during 2018.
Our alternate methodology for estimating median household income from data reported by the U.S. Bureau of Economic Analysis would put the figure at $64,002 for March 2019, which is within 1% of Sentier Research's estimate for the month. We suspect that's because the source personal income data may be showing the effects of past momentum, which may be subject to revision during the next several months.
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.
