The phrase “economic mobility” refers to the likelihood that a child will end up in the same or a different economic strata than their parent.  Education is usually cited as a key to improving economic well-being intergenerationally. Conversely, but often unstated, is the idea that if a child of college graduates doesn’t attend college, than they should perhaps do worse than their parents.

What does the data say?

The figure below is from the Pew Economic Mobility Project.  Along the horizontal axis is the parent’s household income quintile: economic strata broken up into fifths from the lowest (left) to highest (right).  The bars represent the adult child’s income for those who didn’t graduate from college (red) and those that did (blue).

Often we focus on the left side.  Does attending college help poor and working class Americans?  The answer is yes. Only 10% of children born into the bottom 20% of household incomes will grow up and stay in the bottom 20%, compared to almost half of people who don’t go to college.    It’s similar, if less stark, for those in the 2nd to bottom quintile.

But what about the rich kids?  I want to look at the right side.  Notice that a quarter of kids born into the top quintile stay there even if they don’t get a college degree.  Half of non-degree earning children will stay in the top 40% of income earners.

Among the richest kids who do go to college, about 50% will remain in the top quintile.  There are lots of reasons for this, but one is paternal connections.  One study found that a whopping 70% of sons of the 1% had worked for the same employer as their father.  I wonder how high that number would be if we added daddy’s friends?

In sum, it’s hard to go up from down below, but it’s also relatively easy to stay sitting pretty if you’re already way up there.
