To return to the notion of birth deficit, it must be understood that this deficit is relative to the maintenance of a given population with regard to an economic vision.
From a naturalistic point of view there is no birth deficit in France, the birth rate largely allows the survival of the French.
On the other hand, from a demographic point of view, we are moving towards stagnation and then towards a decrease in the population, this is not dangerous in itself biologically, but the question worries economists, because fewer births means fewer consumers. and less savers!
It is also on this last point that the voters of the extreme right bump: immigration is a way to keep the population on the rise.Hors given that its political parties do not want immigration while wanting to maintain growth, it inevitably faces a dilemma, because there is little to expect from birth rates.

Although apparently unrelated, there is a causal link between the
dénatalisme and infertility, it is about two processes induced by the same phenomenon: the increase of the degree of the dissipation of energy.
If infertility is a health problem, statistical or even natural * it is always because of the sudden increase in standards of living via industrialization and its corollary: the sudden change in equilibrium.
Le
dénatalisme is only the memetic counterpart of its modifications, resulting from the modification of psychisms with regard to the induced transformations.
Pessimo-realist that I am I do not believe in the thesis of the voluntary choice not to have children, but rather to the action of determinism programming individuals not to have any.Historically may have very well demonstrated this phenomenon.
(1) It can not be excluded that some cases of infertility are of natural origin, as in rats.
Some scientists believe that homosexual behavior would be part of evolutionary mechanisms to limit births.
