Household income distribution, 2007
January 13, 2009
The graph below shows a histogram of the household income distribution in the US in 2007. It was constructed using data from the Current Population Survey (CPS), Table HINC-06. I smoothed the table by merging pairs of $2,500-wide intervals into $5,000-wide intervals, since the narrow intervals showed marked oscillation, as people apparently tend to report their income in multiples of $5,000.
The three vertical dashed lines indicate the 25th, 50th and 75th percentiles. The corresponding values are $25,100, $50,300 and $88,400, respectively.
The following table gives the deciles of the distribution:
All percentile points were calculated by interpolating linearly within the income bins.
