Are there many out of state students

My S is considering ECU but we are from Maryland. Understanding it is a state school, are there many out of state students who attend? Since many students are from within state, do many students go home on the weekends?

By State legislation at least 82 % of students must be from NC at all state schools.

Therefore around 18 % are out of state.

I would doubt it, NC is a big state, even in state students would likely be several hours away from home
