Worldwide fertility rates have fallen drastically between 1950 and 2017, according to a new study published in The Lancet medical journal.The fertility rate drastically decreases
The fertility rate has been adjustedAccording to the study, almost half of the countries of the world are now not enough children are born to maintain the size of the population. According to figures, in 1950 women gave birth to an average of 4.7 children, while by 2017 the fertility rate was almost halved, to 2.4 children. There are also differences between countries, with women averaging 7.1 in West African Niger and one in Cyprus, the eastern basin of the Mediterranean. When a country's average fertility rate is around 2.1 below, depression begins to shrink over time. (In countries with high childhood mortality rates, the minimum number of births required to maintain the population is much higher.) At the beginning of the study period, that is, in 1950, no country in the world fell into this category. "- We come to the water picker when in half of the countries of the world the fertility rate does not reach the level required for maintenance, that is, the rate of depletion in these countries, "said Christopher Murray, a professor at Washington University.
In developed countries, the rate is lowerIn economically more advanced countries, most European countries, North America, South Korea, and Austria, productive rates are lower:this does not mean that there is a decrease in the population in these countries, at least not yet, since a population size is birth and death rates, and exodus is jointly defined. It may take up to a generation before changes in fertility rates begin to affect them. According to researchers, while half of the countries in the world still have enough children, as more and more nations consider themselves to be economically more advanced, more and more countries will have lower birth rates.

The expert believes that workplaces will need to introduce a number of changes and rethinking, which is currently maximized in the UK at the age of 68. Researchers also recall thatWhile change can bring societies to life with great challenges, it can have a number of profound effects on the nature tested by humanity.Related links:
