Comment: A statistical blimp (Score 4, Interesting) 900
“This is a fascinating phenomenon and nobody has really much idea of what’s going on. What we do know is that it’s absolutely essential to not jump to conclusions about what’s going on. Time and time again over the decades past demographers have been brutally misled by short-term phenomena, by statistics gathered only over a few years. Blips happen for all manner of impenetrable reasons. In this case we’re talking about people born in a small segment of time, around 1900, and most of them born in particular countries and going through certain types of life they might not have gone through had they been born 20 years previously or 20 years later. There are many factors called ‘cohort effects’ that can cause early life phenomena to have an influence on longevity.” Bottom line: don’t believe the hype.
