The graph is a bit hard to read since it's labeled poorly. The X-axis is the year. The Y-axis is the percentage of income relative to 1979, after-tax. They do not mention if these numbers were adjusted for inflation, but the report linked to on the page says the numbers are adjusted for inflation: Income is adjusted for inflation using the Bureau of Labor Statistics’ research series of the consumer price index for all urban consumers (CPI-U-RS). -http://cbo.gov/ftpdocs/124xx/doc12485/10-25-HouseholdIncome.... That report is much more detailed than the Economist's summary. So, in 2007 the top 1% made ~375% of what they did in 1979 (~275% gain). In 2007 the bottom 20% made ~120% of what they did in 1979 (~20% gain). |

The graph is labelled "US real average after-tax income" (emphasis mine). Real income is, by definition, income that has been adjusted for inflation.
