1 Based on analysis on US median household income, median household money income during the 2006-2012 period had an average (but not median) of $53,836, therefore by comparison the Gallup result is underreported and is even below the Census' own figures.
It is a challenge to get your hands on this data since a big portion of income figures are reported via median household income. In the US, the latest Census figures from 2008 to 2012 show that a typical household earned $53,000. Per capita income in the last 12 months came in at $28,000. This tends to surprise people especially with the high cost of living that has been brought on by the slow process of inflation.
