Average incomes

An interesting website at visualizingeconomics.com has lots of graphs of historical average incomes in the US, historical tax brackets, etc. Strangely, I don't see anywhere on it whether the historical incomes are adjusted for inflation, though it seems obvious they must be. Average income in 1913 was around $14,000 according to the graph. The top of the lowest tax bracket that year was an inflation-adjusted $453,292. That was the last time the gap was anywhere near that big. In 2006 the graph of income shows an average of about $50,000 per year. The top of the lowest tax bracket was an inflation adjusted $16,806 for a married couple and $8,403 for a single person. The tax rate for the lowest bracket in 1913 was 1% (one percent). In 2006 it was 10% and still is today, at least until the end of this year.
