The median household income in the United States is $59,039.
This figure from the U.S. Census is actually the figure from 2016, reported in September of 2017. It is the latest figure available.
Note that technically the median is not the same as the average, though we are using the two terms interchangeably here. The median income is the absolute middle, meaning there are the same number of households above that number, and the same number of households below.
Median is actually a better representation of today’s world than the average would be, because income averages are inevitably skewed by the super rich at the top of the scale, making the “average” household appear to be wealthier than it is. (Remember that the average would be the total of all households’ income divided by the number of households. If Bill Gates’ household makes $1 billion per year and 99 other households make $40,000 – $60,000, we would not consider the average of $1 million+ to be truly representative of that group of households. That is how the super rich can alter this type of statistic.)
