is accentuated aging of the population in rich countries
Fewer and fewer assets to keep liabilities, in the world's population, says a study released in the United States.
The aging population is growing in the richest countries and threatens their way of life, threatening their health systems and retirement. In 1950 the world had 12 people working for every retired person or more than 65 years. In 2010 this ratio dropped to 9, says a study by the Population Reference Bureau (PRB).
In 40 years, when the average student of the Faculty of Economics, UNE, has the opportunity to apply for a retirement, ie, in 2050, the ratio of assets held for more older persons will be 4 to 1, says the research institute non-profit specializing in the analysis of demographic data, mainly supplied by the United Nations. "Today we witness a double tendency of the global population." On the one hand, we have a chronically low fertility in industrialized countries, which begins to compromise the health and financial security of older "
"On the other hand, developing countries every year added more than 80 million individuals in the population. Solo the poorest of these countries account for 20 million each year, increasing poverty in the world and pressure on the environment "
The world population in 2010 to 6,900 million people, and all growth lies in developing countries. The people of Africa, for example, will have doubled by 2050 and will reach 2,000 million. By contrast, developed countries, which are 1,200 million people will attend the aging population. In Japan, for example, where the fertility rate dropped to 1.4 children per woman, only there are 3 adults per retiree, the relationship lowest in the world with Germany and Italy, said the report. In 2050 Japan will have no more than an adult of working age for every retiree. Germany, Italy and France will have a ratio of 2 to 1. United States, currently with a ratio of five assets for every person, will drop to 3 to 1.
population of 7,000 MILLION
"The world population will reach in 2010 to 7,000 million people, just twelve years after having reached the 6,000," says study .
The study provides comparisons say much about the evolution of the population. Thus, Ethiopia and Germany now has almost the same population (85 and 82 million respectively), but the Ethiopian population will double by 2050, while Germany will fall to 72 million due to a very low fertility rate (1.3 children per woman, against 5.4 per woman in Ethiopia).
ECONOMIC CRISIS
The economic crisis also seems to have caused a decline in birth rates in industrialized countries, the report said, citing among other countries, Spain and the A gone.
With the approach presented here, the student must reconcile the academic content of Units 8, 10 and 11 to be developed soon.
