How do I find out where students at a college come from?

<p>So I was wondering if there's a way for me to find out where students at a college come from? Like I live outside of Philadelphia and I'm trying to find out what colleges other kids from philly go to. I've found a bunch of stuff about "X amount of students from Pennsylvania go to school in <strong><em>State</em></strong>" but I want to know more specifically "X amount of students at <strong><em>ThisCollege</em></strong> come from the Philadelphia area."
Does anyone know where I can find data like that? I've been scouring the web for a couple days now and pretty sure finding that kind of information takes some special knowledge, so coming here to ask (maybe a college counselor would know??). I might just resort to looking up the matriculation info for college bound high schoolers at specific high schools in the area, but that's gonna take such a long time :(</p>

<p>Thanks sooo much for your help.</p>

<p>The National Center for Education Statistics Integrated Postsecondary Education Data System has data on the state of residence for incoming first-year students. So for any given college, you could tell how many first-years came from Pennsylvania. You could also rank all colleges on the number or proportion of first-year students who came from Pennsylvania. Unfortunately that data does not get down to the county level or deeper, so you wouldn’t be able to focus in on Philadelphia.</p>

<p>If there are specific colleges you’re interested in, you can ask the admissions or institutional research offices there for detailed information on the permanent residence of incoming first-year students. I’ve done that more than once for prospective students.</p>
