The World Health Organization [WHO] reports that birth rates, in many nations, have decreased to a point inadequate for the maintainance of the work force and taxbase needed to support longer living retirees.
Knowing that the fertility rate of 2.1 births per family unit is the average needed to maintain a nations population base, the WHO reports: Germany at 1.35, Spain 1.15, Romania 1.32. Italy 1.32, France 1.89, Sweden 1.64. UK 1.60. Switzerland 1.41, Russia 1.14 and Austria at 1.28.
In America, the population is increasing based on a fertlity rate of 3.11 in the Latino population group. 2.19 in the black and 2.1 in the white population group.
The decline is almost entirely due to Contraception and Abortions [Medical and Surgical] which are safe and effective and widely used either to avoid or end a pregnancy.
At least one major nation has increased resrictions on the availability of Abortions. Others are likely to follow.
