June 29, 2008: Bigger Europe

[Undertoad]

Europe already faces a severe depopulation problem. It's written about today in a NY Times Magazine section article:

In the 1990s, European demographers began noticing a downward trend in population across the Continent and behind it a sharply falling birthrate. Non-number-crunchers largely ignored the information until a 2002 study by Italian, German and Spanish social scientists focused the data and gave policy makers across the European Union something to ponder. The 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. At various times in modern history — during war or famine — birthrates have fallen below the replacement rate, to "low" or "very low" levels. But Hans-Peter Kohler, José Antonio Ortega and Francesco Billari — the authors of the 2002 report — saw something new in the data. For the first time on record, 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. Kohler and his colleagues invented an ominous new term for the phenomenon: "lowest-low fertility."
