A Decade With No Income Gains - Economix Blog - NYTimes.com

The typical American household made less money last year than the typical household made a full decade ago.
To me, that’s the big news from the Census Bureau’s annual report on income, poverty and health insurance, which was released this morning. Median household fell to $50,303 last year, from $52,163 in 2007. In 1998, median income was $51,295. All these numbers are adjusted for inflation.
