In almost half of the world, fertility has declined significantly, which means that the affected countries do not have enough children to protect their population according to a study published in the Lancet.
Often in 91 countries in Europe and North and South America, 91 countries are not born enough to protect the present population.
The researchers were surprised by this finding because the study also shows that fertility is still in developing countries.
Global research on the birth, death and diseases of the IHME research institute based on country data has surprisingly demonstrated the growth of the world's population for dizziness of 2.6 billion people rising from 1950 to 2017. 7.6 billion, extremely unequal and according to these regions and income. For the survey, which is one of the most detailed surveys of global public health, IHME examined 8,000 new data sources, 600 of which were new.
Founded by the Bill and Melinda Gates Foundation at the University of Washington, the institute found that 91 countries in Europe and North and South America often do not have enough births to protect the current population. The smallest country born in Europe is Cyprus, because there is only one child born there. In Slovenia, according to the spreadsheet, the IHME produces an average of 1.5 children. On the other hand, between 1950 and 2017, fertility continued to increase in Africa and Asia.
