Statistics on People Getting Degrees

I read a report from the Economic Policy Institute (EPI) about statistics on schooling. The EPI is a non-profit organization that looks at economic trends that affect the working class in America. The best stats I gained from their report was the percentage of people who achieve degrees. Now they slice and dice those numbers all kinds of ways. I was most interested in the numbers for people aged 25 to 54 years of age. Here are the rough percentages:

10% did not finish high school
25% got just a high school diploma
25% took some college classes
25% got a bachelor's degree
15% got an advanced degree

What I like to do it turn those groups into a rolling percent of how many people you have surpassed, just by achieving a degree:

Get a high school diploma to have surpass 10% of the people.
Just attend college to surpass 35% of the people.
Get a bachelor's degree to surpass 60% of the people.
And get an advanced college degree to surpass 85% of the people.

Seems like the bachelor's degree is the sweet spot. It will put you in the top half of the population based on schooling alone. I am always looking for an edge to set me apart from the next guy. When you have extra credentials, it is easier for someone to give you a job (and a higher paying one at that).
