520			_aThe preceding edition of this book was issued during World War II (1942). At that time it was impossible to secure as much up-to-date mate rial on population as was needed to keep current with population changes. In particular, the censuses of many countries were not taken, and the results for others were not published in the customary detail. Since 1940 much water has gone over the dam. A truly surprising amount of study of population questions has taken place during the past dozen years. As a consequence this revision does more than add new data. It is in many respects a new book. Almost all of it has been rewritten, and the author has tried to embody in his rewriting the more significant additions which have been made to our knowledge of population growth and changes in recent years. Unfortunately, in the field of population study as in so many other fields of social science we do not yet possess enough information to make possible wholly objective interpretations and analyses when treating of many aspects of population growth and change. This means that we must often resort to opinions and to general observations when trying to assess the probable consequences of trends and changes in the population.
