Real Household Income

Interesting chart showing the disposable income. Over the past decade, real income has basically gone nowhere for the median household.

'Real' income means that it has been corrected for changes in the CPI. For example, if your salary increases by 5% but the prices of goods and services also increase 5%, then your 'real' income in terms of purchasing power has not changed.

There is a fair amount of evidence that the goverment is under reporting the CPI and has been for many years. Some estimates suggest that if we compared apples to apples with older methodology, the CPI is increasing at triple the currently reported rates.

If that it true, then what is the real trend in real disposable income over the past decade?
