Answer:
Europe
Explanation:
With regard to the demographic situation, the fact of how on the European continent the majority of its inhabitants corresponds to an adult population between 30 and 50 years of age, with a progressive aging and a marked decrease in the juvenile population. This situation is already worrying in several European countries, such as Germany, Austria, France, Switzerland, Belgium, the Netherlands, Spain, the Scandinavian countries, Denmark, Greece and the United Kingdom, in which there is an inverted population pyramid with a small population juvenile and above all childish. This phenomenon also occurs in Eastern Europe, where in the decade of the 90s of the 20th century, the fall of communism caused a collapse of the birth rate, already low in the European communist countries, together with a sharp increase in the mortality. In recent years, the fall in the birth rate in the former communist bloc has been muted, which has allowed a recovery of birth rates closer to the current population stabilization (1.5 children per woman). In countries such as Ireland, Italy, Portugal and Iceland, the aging process was also installed in society, which causes the population of these countries to decrease annually and not even immigration manages to cover this problem.
