Martin and list,

Actually, there is something suspicious. Northwest Africa (the
countries you listed plus Western Sahara and Tunisia) has seen between 0
and 3 falls per decade from the 1900s through the 1980s. The 1990s saw
6, and the 2000s have now got 8. There is no parallel increase in the
rest of Africa, which in fact has been steadily declining in fall rates
since the 1940s. Europe has also been declining since the 1930s (in
fall rates), as has North America. I think northwest Africa is the only
place in the world that is seeing any kind of increase in rate, and it
has been dramatic, tripling in the last decade.

The are various sociological reasons why this increase might have
happened, which we can argue about. But there certainly IS something to
raise ones eyebrows.
