I think that you can take a bit from each of these answers. You may want to think about what school you want to send your kids to and then look at the neighborhoods near there. Like Vera said, there are kids in most neighborhoods. But, I think you should base the decision on what kind of education you want your kids to have and how long of a commute you can live with. Good luck!
I'm sure there are, but I'm not sure if there is a way to document which neighborhood. Truthfully we are always careful with these questions because we don't want to discriminate one neighborhood over another. You could check on the school ratings to see which grade schools are rated very high and look for homes around those schools. Many people choose a neighborhood which is near services they value.
I've attached a link to the State School Report Card. I've found this to be a very helpful tool when comparing one school or one district against another. I hope this helps.
