Educational attainment and occupational patterns are key factors in explaining the above-average household incomes for Asian Americans as a whole—a median $66,000 in 2010, vs. $49,800 for the U.S. population—and for most country of origin groups.
Median income may also be viewed in the context of number of earners per household and household size. Asian-American households have more earners on average than U.S. households overall—1.6 compared with 1.4. Additional earners help boost overall household income.
In addition, the average Asian-American household (3.1 people) is larger than the average U.S. household (2.6), and larger households mean that income must be divided among a larger number of people.
