"Academics come first hands down so male/female ratio and party scene aren't too important."
Part of college is to have fun, because once you are older, you're not "allowed" to be irresponsible like you were in your college days. I studied engineering, and looking back, I wish I had been to more parties and met more people.
When you start interviewing for jobs, you need to be able to hold a conversation, be interesting, talk about different things, and generally be a likable person. An active social life will help you with that.
Life isn't all about academics - enjoy it a little.
