In recent weeks, we have been focusing on Greece, Germany, Ukraine and Russia. All are still burning issues. But in every case, readers have called my attention to what they see as an underlying and even defining dimension of all these issues — if not right now, then soon. That dimension is declining population and the impact it will have on all of these countries. The argument was made that declining populations will generate crises in these and other countries, undermining their economies and national power. Sometimes we need to pause and move away from immediate crises to broader issues. Let me start with some thoughts from my book The Next 100 Years.
Reasons for the Population Decline
There is no question but that the populations of most European countries will decline in the next generation, and in the cases of Germany and Russia, the decline will be dramatic. In fact, the entire global population explosion is ending. In virtually all societies, from the poorest to the wealthiest, the birthrate among women has been declining. In order to maintain population stability, the birthrate must remain at 2.1 births per woman. Above that, and the population rises; below that, it falls. In the advanced industrial world, the birthrate is already substantially below 2.1. In middle-tier countries such as Mexico or Turkey, the birthrate is falling but will not reach 2.1 until between 2040 and 2050. In the poorest countries, such as Bangladesh or Bolivia, the birthrate is also falling, but it will take most of this century to reach 2.1.
The process is essentially irreversible. It is primarily a matter of urbanization. In agricultural and low-level industrial societies, children are a productive asset. Children can be put to work at the age of 6 doing agricultural work or simple workshop labor. Children become a source of income, and the more you have the better. Just as important, since there is no retirement plan other than family in such societies, a large family can more easily support parents in old age.
In a mature urban society, the economic value of children declines. In fact, children turn from instruments of production into objects of massive consumption. In urban industrial society, not only are the opportunities for employment at an early age diminished, but the educational requirements also expand dramatically. Children need to be supported much longer, sometimes into their mid-20s. Children cost a tremendous amount of money with limited return, if any, for parents. Thus, people have fewer children. Birth control merely provided the means for what was an economic necessity. For most people, a family of eight children would be a financial catastrophe. Therefore, women have two children or fewer, on average. As a result, the population contracts. Of course, there are other reasons for this decline, but urban industrialism is at the heart of it.
