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.
According to this information 151 million Americans earned some sort of wages or compensation in 2011. The median wage in the US per person is $26,695. This tells us a lot since the median household income is at $50,500. Since the Census data looks at households, this data hones in on individual wage earners.ccording to this information 151 million Americans earned some sort of wages or compensation in 2011.
