Foreign differences between countries

The differences between the individual countries are Iranian. An average of 7.1 in West African Niger and one in Cyprus in the eastern basin of the Mediterranean, women are born - reports the BBC. (In countries with a high childhood mortality rate, 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 belonged to this category. in half the countries of the world the fertility rate does not reach the level required for maintenancethat is, the rate of depletion in these countries, "he said Christopher MurrayProfessor at the University of Washington.In the more economically advanced countries, most European countries, North America, South Korea and Austria, the productive rates are lower. This does not mean that there is a decrease in the population in these countries, at least not yet, since the size of a population is determined by birth and mortality rates, as well as by migration.
