Restated Question: What website describes student demographics?

Question

I want to know what gives non-traditional undergrads a chance at enrollment when completing against undergrads that pay more by living on campus?

Answer 1

There's no one website like that, but in answer to your question, admissions at most colleges are need-blind. That means that admission officers have no idea who will be able to pay what proportion of tuition, fees, and room and board costs.

As a matter of fact, many colleges have altogether separate admissions processes for traditional and non-traditional students, so non-traditional students are not competing against those right out of high school.
