Some interesting income data

Dalrock has some interesting data at his site which looks at the earnings of unmarried people in the U.S. by age group. One of the conclusions Dalrock draws is something I also noticed:

I am astounded at the number of unmarried men and women who earn either nothing or extremely small amounts.

The following graph shows the earnings of unmarried men and women aged 30 to 34, an age at which you would expect most people to be finished with study. There are more women than men earning a low income, but even the figure for men is striking. There are 17% of men earning no income; 34% earning less than $15,000 and 68% earning less than $40,000.
