The idea that college isn't really worth the hefty price tag (not to mention the daunting student loans) has been called "one of the year's most fashionable." But according to a Pew Research Center analysis of Census Bureau data, that buzzy idea may very well be wrong, at least in economic terms. The survey found that the typical adult with a college degree makes $550,000 more over a 40-year career than the average high school graduate. And yet, a second Pew study found that the majority of Americans don't think college is worth the money. Here, a brief guide, by the numbers:

$1.42 million
Amount the typical adult with a bachelor's degree makes over a 40-year-career

Amount a high school graduate makes over those 40 years

The difference in income over 40 years between a college and high school graduate

Median gap in annual earnings between high school and college graduates

Percent of adults who say they expect their kids to go to college

Percent of adults who say America's higher education system doesn't provide families and students with good value for the money

Percent who said they are saving for college

Percent who said college was too expensive for the average American to afford

Factor by which the cost of college has multiplied, roughly, since 1980, adjusting for inflation. That's from around $10,000 annually to roughly $30,000.

Amount of debt the average 2011 college grad leaves school with, making this year's class the most indebted class ever

Percent of adults between 18 and 34 who don't have a bachelor's degree, and aren't in college, who say they would prefer to work than go to school

Percent of students who showed no improvement in critical thinking, complex reasoning, and writing after their first two years of college, according to research cited by Richard Arum and Josipa Roksa, authors of Academically Adrift: Limited Learning on College Campuses

Percent of college grads who say "their college education was very useful in helping them increase their knowledge and grow intellectually"

Percent who said it was "very useful" in helping them get a job or start a career

Percent of freshmen who spent less than 15 hours per week studying, according to a study by the National Survey of Student Engagement
