The charts that follow summarize the number of athletes each country placed in the world top-100 rankings for 2001 (plus ties) and the highest-ranked of these for each event. Since one or two placings may represent only exceptional individuals, rather than national program strength, I've truncated the lists to countries with three placings or more. The data base drawn upon is the world list from Mirko Jalava's web site <http://www.tilastopaja.com/>.

The widest distribution I've observed in any event thus far was that of the 1999 men's long jump, with 44 countries represented in the top 100.) MEN'S 1500m 2001 WOMEN'S 1500m 2001 Country Top 100 Highest Country Top 100 Highest Kenya 27 2 Russia 14 2 United States 11 23 China 12 40 France 10 11 United States 10 4 Spain 8 7 Romania 5 1 Morocco 7 1 Great Britain 5 14 Great Britain 6 34 Kenya 4 10 Algeria 4 4 Germany 4 18 Germany 4 70 Ukraine 4 25 Ireland 3 42 Ireland 4 33 Turkey 4 37 Ethiopia 3 27 Spain 3 32 Australia 3 60 22 countries represented 33 countries represented 100th = 3:39.06 100th = 4:12.23 (This time, an unusually narrow distribution in the men's event; but not so narrow as that in the women's marathon, where there were only 18 countries represented.)
