Are you middle class? Take our quiz to find out.

It's undeniable the middle class is growing in China, Brazil and India. But in the US, the term "middle class," is notoriously vague. Almost everyone, it seems, identifies themselves as middle class, regardless of wealth, income, profession, or education. That's why most politicians will describe policies they oppose as "punishing the middle class" and policies that they support as "helping the middle class."

One popular definition, provided by The Drum Major Institute for Public Policy, identifies American families as middle class if they have incomes between $25,000 and $100,000 each year. That's a wide spread, but a perhaps a useful one: If you see someone who makes $75,000 a year more than you as belonging to your class, you're much less likely to revolt against them.
