The UN estimates that the world population will be 9.7 billion in 2050
On Monday, the United Nations Organization published a report in which it is estimated that the world population will grow from 7,700 (current figure) to 9,700 million in 2050.
The main source of this growth is, according to the UN, in sub-Saharan Africa, where the number of inhabitants is expected to double.
Through the forecasts that the UN is revealing, it is estimated that in the same way as in 2100, the human population is approximately 11,000 million.
The report named "Perspectives of the population in the world", Of the same organization, also points out that the aging of the human race will lengthen thanks to the life expectancy that is increasing more and more and to the decrease of fertility.
The predictions of the United Nations Organization
Among the predictions of this international organization is one very interesting about the country that currently has the highest number of inhabitants in the world.
The population of China will suffer a reduction of 2.2% (31.4 million inhabitants) between 2019 and 2050.
The main reason for population growth in various countries
The migratory movements is one of the reasons why several countries will have a considerable growth in their population.
Belarus, Estonia, Germany, Hungary, Italy, Japan, Russia, Serbia and Ukraine; These are some of the countries in which this prediction can be verified in the future.
Already placing us in the year 2050, the majority of the world population growth figure will stand out above all in 9 countries:
India, Nigeria, Pakistan, Democratic Republic of the Congo, Ethiopia, Tanzania, Indonesia, Egypt and the United States.
Births will decrease
In the year 1990 birth statistics, worldwide, decreased from 3.2 to 2.5 in the current year 2019. By 2050 it is expected to fall and remain at 2.2.
The UN report also indicates that the rate of 2.2 mentioned above is close to the rate of 2.1 births per woman; obtaining these results, generational replacement would be achieved without problems and would not allow for a gradual fall of the population in the absence of immigration.
Life expectancy in 2050
Poor countries will continue to have an average life of seven years less than the global average. In 2050, the average life expectancy is expected to reach 77.1 years, instead of the 72.6 that we currently have.
Interestingly, in 1990 life expectancy was 64.2 years.
