Median income for males, in 2008 dollars, from US Census data.
Why those three years? 1947 is the year the data begins, 1973 is the year of peak earnings, and 2008 is the last year for which data is available.
We see that from 1947 to 1973, everyone’s income increased.
From 1973 to 2008, the 65+ age group saw a continued increase in income, and the 55-64 age group had their income hold steady. The biggest losers were the 25-34 age group which saw a 24% decline in real income.
The reason why the number of young men who live at home keeps going up each year (a continuing topic at the NY Times) is because the percent of parents whose income is far greater than their sons’ keeps increasing each year. I wonder what the 2009 data will look like?
