Hello Familyoriented and welcome. I really don't have any statictics to offer you and I don't want to sound clishe, but I think it really doesn't matter much where you raise your children as long as they have are raised with love, compassion, understanding and most of all with the Lord. I also think that if you are making the decision to live in an apartment for the right reasons, like it being financially wise, that can only be beneficial to your children as you are teaching them it is the right thing to live within their means. So, if I were you, I would just pray about it and go with what I have peace about doing. The Word says to let peace be your umpire, meaning if you have a knot in your stomach about a decision you're about to make, you probably shouldn't make it but if you feel peace about it no matter how strange it might seem to other people, go with that. God will guide you and whatever decision you make, if it is the one you have peace about it will work out!
