As I said York is quite small compared to Birmingham, so private rent is gonna be cheaper for sure! I was having a look online before being allocated a room at one of the colleges, private rent is usually 70-90 pw + utilities. As for the on-campus accommodation, it is the same as the private one give or take. Only it's on campus which means always being on time for lectures :-)
As for the number of international students I really don't know about the statistics, sorry.
Are you from the EU? If you don't mind me asking.
'Cause if you are, then you will be eligible to apply for on-campus accommodation (at one of the colleges) but you will not be guaranteed a room. If you are from outside the EU, you will be allocated a room for certain.
The reason I am saying all this is that when I applied for accommodation (and that was during the first half of June) most of the en suite rooms had already been taken and I had to settle (i did get an en suite, just not at the college I wanted, 'cause there weren't any left).... This is all' cause I am from the EU, if you are not then that's a completely different story!
The point I was trying to make was: if you are from outside the EU take all the time you need, otherwise think fast because either here or at Birmingham non-EU students are always gonna be privileged when it comes to being allocated a room.
If you are still waiting for an offer from Birmingham, do what I did for York and phone them up: since I wanted to get into their programme so badly but had other offers that were about to expire, I gave them a call half a month after submitting my application and spoke to the department of computer science who told me that I had been recommended, so I waited for their letter :-). If they had told me that I didn't meet their requirements, I would have chosen one of the others who had given me an unconditional offer :-).
So when you have some time, give the university of Birmingham a call and ask their department of computer science about your application :-)
When you apply for a programme at any uni, the admissions' office usually sends the application down to the correct department who then make the actual decision :-)
Depending on when you sent in the application, they might have already made up their mind, but the uni's admissions' office might have not forwarded you their decision yet :-) ( cut them some slack, this is one of the busiest times of the year for them :-) )
Good luck with whichever uni you end up choosing :-)
