Reports of America's Demise Premature?

As RTP&GG readers know, one of my mantras is 'Demography is Destiny'.  A website I like is New Geography because one aspect of geography is demographic analysis.  Anyway, they have a neat article in the manner of 'America's future is dark, except when compared to all its rivals' that shows that we aren't quite the nation of eunuchs that most of our chief rivals, uhum China, uhum Russia, uhum Eurowusses, uhum Japan are.
