Why does tuition cost more for out-of-state?

Question

I never understood. In some colleges/universities the price difference is not a whole lot, but I've seen others that have like a $5000 to $8000 difference for the in-state and out-of-state. Can someone explain this?

Answer 1

State funded/public colleges charge more for out-of-state students to make up the part of tuition that taxes cover for state residents.

Answer 2

Because most states are trying to keep and increase their population. If someone goes to college in their home state they are more likely to stay and get a job in their home state. It's insentive to stay in your state and it's economic revenue.  

Answer 3

It's mainly about taxes. If you live in the state you pay taxes to that state, but if you just moved there all your money up to that point went to another state. Public colleges are state-funded.

Answer 4

State colleges and universities are supported largely by tax revenues from the residents of the state.  The "discount" offered to in-state residents reflects that the families of students have already been playing for the cost of the college via their state taxes for years.  Out of state residents have been paying nothing for the cost of colleges since their family pays taxes to different states.
