There is much variation in the weekly earnings of college graduates. In the last quarter, 10 percent of college graduates earned less than half of the median amount for those with a college degree. Another 10 percent earned more than twice the median amount.
The usual median weekly earnings of college graduates were $867 in the three-month period from July to September 1999. College graduates in the first decile in earnings—the lowest 10 percent—earned less than $428 per week. This was just under half of the median level.
Workers with a college degree who were in the tenth decile—the highest 10 percent—earned $1,749 per week or more. This was just over twice the median level of earnings of college graduates.
