The U.S. median household income was $63,179 in 2018, not statistically different than the previous year, according to U.S. Census Bureau statistics released today.
At first glance, it would appear that median income was higher than every year prior to 2017, surpassing the median income for 2007 ($60,985 in 2018 dollars) and 1999 ($61,526 in 2018 dollars).
In 2017, the median income was $62,626, not statistically different from 2018. So, making comparisons prior to 2017 requires caution, since recent estimates reflect changes implemented to the survey.
The 2018 income, poverty and health insurance statistics released today come from the Current Population Survey Annual Social and Economic Supplement, known as CPS ASEC.
