Although I am not from Utah County, I do know from experience that if you were to buy in a new development, young families with lots of children seem to appear. So, while I can't tell you specifically which neighborhood would be best, I do have a list of new home developments by Ivory Homes that might help.
Many of Ivory Home communities have a pool, clubhouse, and other amenities that you may enjoy.

I think, and someone please correct me if I am wrong, that the areas in which you will find younger families would be Saratoga Springs and Eagle Mountain. That isn't to say that you won't find them in the other cities, but those are the "newer" towns and many young families were buying down there because of the lower cost of homes at the time.
Utah County is very conservative. No worries there...you will be okay wherever you live.
