United Nations Demographic Yearbook 1949-1950

image of United Nations Demographic Yearbook 1949-1950
This is the second issue of the United Nations Demographic Yearbook. In the first issue, current statistics related chiefly to 1947 and historical series ended with 1947. In the present volume, as a result of a forward shift in schedule, it has been possible to include data not only for 1948, but in many cases for 1949 as well.

World population trends, 1920-1949

In spite of a steadily increasing volume of reliable population statistics, the task of assessing world population trends remains a formidable one. Reliable population estimates still do not exist for a considerable part of the world. The position with regard to vital statistics is even more unsatisfactory. At some time in the future it may be possible to estimate accurately the population of the entire world and to analyse with some precision the processes of population change in all the regions of the earth. In the meantime there is a persistent demand for the best possible estimates of the size and growth of world population, though it is realized that errors and uncertainties are bound to be present in the results of even the most careful analysis.
