The Developed Areas comprises Western Europe (exclud 
ing Spain, Portugal, Greece and Turkey) United States, Ca- 
nada, Japan, Soviet Russia and other socialist countries; the 
Underdeveloped Areas comprises all other countries. Since 
these estimates, compiled from United Nations and other sta- 
tistical sources, are supposed to cover all countries, they ob- 
viously are subject to a very substantial margin of error. The 
estimates of the annual rate of gross productive investment in 
the Underdeveloped Areas, which is particularly uncertain, is 
presented not as a single figure but in terms of two figures — 
a high and a low — which does not mean of course that the 
true magnitude still might not lie outside of that range. 
For similar reasons the base year estimate of the long-run 
growth rates of the GNP’s is also presented for each area in 
the form of two percentage figures — a higher and a lower one.
