In 1990 7.3% of the civilian noninstitutional population was enrolled in college or graduate school.
In 2016 that has grown to 8.1%.
The difference in 2016 comes to almost 2 million.
That's one reason why college tuition has exploded, along with the student loans to fund it.
Loans outstanding in 2016 are FIFTY-ONE TIMES their size in 1997.
The current balance of $1.05 trillion is an artifact of the Obama disaster, financing "education" for the chronically unemployed.
Just ask the kids using their loans to finance Spring Break.
