New United Nations Report(UN), dedicated to global demographic change, reports that by the end of this century the population of the planet will increase to 10.9 billion people. At the same time, by 2050, the Earth’s population could increase by 2 billion, reaching 9.7 billion. According to the UN forecast, 50% of the total population growth in the next three decades will be accounted for by nine countries - India, Nigeria, Pakistan, the Democratic Republic of the Congo, Ethiopia, Tanzania, Indonesia, Egypt and the United States.
There will be even more poor people in the world.
“The fastest growing population ispoorest countries in the world, which leads to additional difficulties in fighting poverty, inequality and hunger, and also undermines efforts to strengthen education and health care systems, ”notes Liu Zhenming, UN Under-Secretary-General for Economic and Social Affairs.
For example, the population of Nigeria from the current 200 million people according to expert forecasts will increase to 700 million by 2100, which will make the country the third largest in the world.
UN experts believe that India will be able to overtake China and take first place in the world in terms of population in 2027. The number of inhabitants of tropical Africa will double by 2050.
Why has the population growth slowed down?
In general, researchers have noted a decrease in worldfertility rates. If at the beginning of the 20th century there were 6 babies per woman on average, by 1990 this figure had already decreased to 3.2, and according to the latest data - to 2.5. According to forecasts, this figure will continue to decline over the coming decades and will reach 2.2 by 2050, and by 2100 - 1.9, which will indicate a decline in the global population by the next century. The report states that the aging of the population leads to a decrease in the number of people of working age, which leads to serious problems related to the social security of the elderly and the payment of pensions.
The report also notes an increase in the number of countries inwhich there is a decrease in population, which is associated, primarily, with the fall in the birth rate. By 2050, in 55 countries, the population will decrease by at least 1%. Among them - Russia, Ukraine, Belarus, Armenia, Latvia and Lithuania.
The population of Russia by 2050
According to forecasts, the average Russian populationcould be reduced to 135.8 million by 2050. If we proceed from the pessimistic forecast of the UN, then the number of Russia will drop to 124.6 million people by the middle of the century. According to the optimistic forecast, it will be 147.2 million people. By 2078, according to the pessimistic forecast, the population of Russia could be reduced to 99.7 million people, according to the optimistic one, to increase to 160 million. The median average for 2078 for Russia is 127.4 million according to the UN forecast.
