No, Meteor Blades, household income does NOT measure the earnings of everyone in the household

 - by New Deal democrat

Real median income measures the INCOME of everyone in the household.

For example, if an 80 year old gets a pension payment, or interest payments on savings or bonds, that is included, even though it is not earnings. Since there are a lot more people over 55, and particularly over 65 now, as a percentage of the population, and they have lower income than prime working age households, real median household income has been in a secular decline.

That's why real median household income has mainly been telling us since 2000 that Boomers are leaving the work force,and now they are retiring in droves. Secondarily, it is a proxy for the employment to population ratio, as increased unemployment means lower income.
