The issue at Ohio State is not just increased admissions standards, but a significant increase in applicants. The past three years, OSU (main campus) has seen applications rise from 27k (2012 graduating seniors), to 35k (2013 seniors), to 43k this past year for graduating HS seniors. There isn't just an increase in demand from those who have OSU as their first choice. Many students looking to get into the Ivy League schools or places like Cal or Stanford or Northwestern are using OSU as their safety school in case they can't get into their top choice(s) or they can't turn down the financial aid package offered to them by OSU compared to what they would be paying at one of the more challenging schools to gain admission to. Every one of those students who are using OSU as a safety net is potentially taking a spot away from a kid who really, really wants to attend Ohio State. Regardless of why you are applying to OSU, the admissions requirements that students faced at OSU in 1995 (and even 2005) was much, much more relaxed than it currently is in 2015.
I've attended workshops with OSU admissions reps and if you're thinking you (or your child) can just look at the ACT and GPA numbers and think you're safe, you may want to reconsider that plan and do whatever you can to make yourself stand out from the pack. And from working with kids who have parents or siblings who graduated from OSU, living in Ohio and being in a family of OSU alums won't automatically help you (unless your parents are big-time donors) as OSU is looking for the balance and diversity that out of state and/or international students bring to the university. And with consistent decreases in state funding, the revenue generated by out of state students may actually put the in-state students at a disadvantage. If you do want an advantage of living in Ohio, OSU admits at least one student from every Ohio county, so if you don't think you can match up with the applicants in a more populated county, I guess you can always move out to the country where you have less competition. OSU also admits one person from every major, so that is an option as well. And if none of these work for you, get really good at a sport which requires a ball because there is always room at OSU (or ND/Virginia/Michigan/Duke/UCLA /USC or any other high profile academic institution) if you can generate revenue for the athletic department due to your superior athletic talents.
As others have mentioned, the branch campuses and Columbus State are ways to get into main campus if you don't make the cut the first time, but those who I have talked to who were presented with these options were not very welcoming to the possibility of attending OSU while living in Lima, Ohio and/or attending CSCC for a year or two. And I probably agree with that. The freshman year experience in Columbus is really unparalleled when looking at the other options a student has who can't get into main campus.
