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.
One is GDP per capita. This takes the total economic output (Gross Domestic Product) of a country and divides it by the number of people. In the U.S, it's around $48,000 a year. Another is median household income. This tells you the income for an average household, which is around 2.2 people per household.It's normally higher than income per capita. The median is the point where 50% of all households are above, and 50% are below. In the U.S., that's usually around $50,000 a year.nother is median household income.
