It turns out that European birth rates have been dropping steadily, and have continued to diminish. According to the New York Times Magazine, "[t]he figure of 2.1 is widely considered to be the “replacement rate” — the average number of births per woman that will maintain a country’s current population level." But by 2002, "birthrates in southern and Eastern Europe had dropped below 1.3. For the demographers, this number had a special mathematical portent. At that rate, a country’s population would be cut in half in 45 years, creating a falling-off-a-cliff effect from which it would be nearly impossible to recover."

And we’re not just talking about Europe, either:

This spring, the Japanese government released figures showing that the country’s under-14 population was the lowest since 1908. The head of Thailand’s department of health announced in May that his country’s birthrate now stands at 1.5, far below the replacement level. “The world record for lowest-low fertility right now is South Korea, at 1.1,” Francesco Billari told me. “Japan is just about as low. What we are seeing in Asia is a phenomenon of the 2000s, rather than the 1990s. And it seems the reasons are the same as for southern Europe. All of these are societies still rooted in the tradition where the husband earned all the money. Things have changed, not only in Italy and Spain but also in Japan and Korea, but those societies have not yet adjusted. The relationships within households have not adjusted yet.” Western Europe, then, is not the isolated case that some make it out to be. It is simply the first region of the world to record extremely low birthrates.
