Only one for me and my husband. Would have liked more, but for population growth reasons I'm happy with one. One of my husband's colleagues just had his seventh child, which I think is nuts.

I found the information at this link interesting. There are a few areas that are experiencing negative population grown and some which, within the next decade, will have negative growth as a result of sub-replacement fertility rates. They did a good series about this subject within the last year or so on PBS.
