Of course, many returns are for households that include additional earners and dependents.
Brad the Acorn Gatherer asked:
Do we know where the top of the fourth family income quintile was for two-adult households aged 40-49?
The answer is still no, but this gets a little closer--
The average 'family economic income' for "families age 40-50" in the 70-80 percentiles (e.g., the eighth decile) was $54,722 in 1994 (Gale, Houser, Scholz) Without the imputations in FEI, this would of course be lower.
Ordinarily I wouldn't be so informative to the list, but I'm working with these numbers right now.
