The Associated Press reports data from a Centers for Disease Control study of last year's birth certificates which shows births are up over the previous year, in all ethnic groups except Native Americans. Teen births are down, those to older mothers are up. Hat tip to the other DrC for the link.
In terms of ours being a successful society going forward, the increase in total births is good news. The article suggests this reflects the economic upturn which statistics show happening but few survey respondents report experiencing. I am unsure this is the cause, although I have no better explanation.
