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 the U.S. Census Bureau, the median household income in the United States is $50,221. Depending on where you live, that amount might be either substantial or skimpy. Analysis of economic data shows that the costs of basic goods like food, clothing, and housing can heavily affect the worth of a salary in any given city. These are the 10 U.S. metropolitan areas (pop. 500,000 or greater) with the highest median incomes, adjusted according to their respective costs of living.
