At the present time some 66 countries have fertility rates which are below the level necessary for population replacement (TFR 2.1). Within the next decade the number of counries in this group is set to grow to the point where a majority of the worldâ€™s population will be living in regions where the existing population no longer replaces itself. This development in an of itself is no disaster – many countries arguably suffer from excessive rates of population increase – but equally reducing fertility too rapidly can lead to economic and social ‘imbalances’ that may well turn out to be, in and of themselves, ‘undesireable’.
Understanding why this is happening has begun to present an important challenge for many areas in contemporary social science as there are evidently factors involved in the process which embrace areas as diverse as demography, sociology, anthropology, psychology, political science, economics and of course biology.
One of the characteristic features of this most recent fertility decline is that it is driven largely by a delay in childbearing: couples (and obviously in particular this means women) wait longer and longer before taking the decision to have a child. Understanding the dynamics behind this ‘delay syndrome’ is the key to developing a social policy to address the consequences, so it is particularly timely that the Vienna Institute of Demography was host last week to a Conference on this very topic: The Postponement of Childbearing In Europe. A number of interesting and important papers were presented, and I will be looking at a number of them between now and xmas. Indeed I have opened a page on my website which will be dedicated to the Conference.
But, just as a taster, why is postponment so important?
