I'd love to see statistics as well.

My wife self-reports as very happy and talks a lot about how proud she is of the decision. I'll acknowledge that we are privileged in terms of support -- 3 relative families within 30 minutes and most people in a 100 meter radius attend the same church. Even in our setup, however, we really wish we could swing a multi-generational setup and have grandparents around all the time.

Maybe the Amish are on to something!
