Median household income in the U.S. rose to to $58,523 in September 2017, up nearly 0.2% from our previous estimate of $58,419 for August 2017. The following chart shows our estimates for the trends for both nominal (red) and inflation-adjusted median household income (blue) from January 2000 through September 2017.
In terms of current U.S. dollars, the most recent trend for median household income in the U.S. has been slowly rising since January 2017. However, after adjusting the nominal income data to be in terms of inflation-adjusted, constant September 2017 U.S. dollars, we can see that since January 2017 has trended mostly flat until recent months, where it has recently dipped thanks to the higher rates of inflation recorded since July 2017.
We believe that most of that change reflects recent increases in the price of oil following the supply disruption of domestic U.S. production following Hurricane Hugo combined with an increase in foreign demand since the end of June 2017, which has reversed what had been a downward trend for these prices.
The methodology for the approach we’ve developed to generate these median household income estimates is described previous estimate. In generating inflation-adjusted portion of the Median Household Income in the 21st Century 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.
For the just released personal income data, the BEA revised the figures for just the previous two months from their previously reported levels, which we’ve updated in this month’s chart. As in previous months (or at least since June 2017 when we began posting our monthly estimates of median household income, the magnitude of the revisions continue to be tiny (on the order of +/-0.04%), with minimal impact to our estimates from one month to the next.
