The UN has published a forecast of the world population by the year 2100
A new United Nations report (UN) dedicated to global demographic changes, reports that the world's population by the end of this century will increase to 10, 9 billion people. In this case, by 2050 the Earth's population will increase by 2 billion people, amounting to 9, 7 billion. According to UN forecasts, 50% of the total population growth in the coming three decades, will account for nine countries - India, Nigeria, Pakistan, the Democratic Republic of the Congo, Ethiopia, Tanzania, Indonesia, Egypt and the United States.
The world will be even more poor
"The most rapid rate of population increase in the world's poorest countries, which leads to additional difficulties in the fight against poverty, inequality and hunger, as well as undermining efforts to strengthen the education and health systems," - said Liu Zhenmin, Deputy UN Secretary-General economic and social Affairs.
For example, the population of Nigeria from the current 200 million people are projected to experts in 2100 will grow to 700 million people, making the country the third largest in the world. UN experts believe that India will overtake China and take first place in the world in terms of population as early as 2027. The population of sub-Saharan Africa in 2050 will be doubled.
Why has slowed the growth of the world's population?
In general, researchers have noted declines in global fertility levels. If at the beginning of the 20th century on a woman on average accounted for 6 infants, by 1990 this figure has already decreased to 3, 2, and according to the latest data - up to 2, 5. According to forecasts, this figure will continue to decline over the coming decades, 2050 will be 2, 2, 2100 - 1, 9, that will testify in the direction of reducing the world's population in 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 of social security of older persons, the payment of pensions.
The report also noted the growing number of countries where population decline is observed, which is due, primarily, with falling birth rates. By 2050, in 55 countries the population will be reduced by at least 1%. Among them - Russia, Ukraine, Belarus, Armenia, Latvia and Lithuania.
The population of Russia in 2050
According to forecasts, the population of Russia in the middle may be reduced to 135, 8 million people by 2050. If we start from the pessimistic forecast of the United Nations, the Russian population by mid-century will drop to 124, 6 million people. According to the optimistic forecast, it will be 147, 2 million people. By 2078 the population of Russia according to the pessimistic forecasts could be reduced to 99, 7 million people, according to the optimistic - to grow to 160 million. Average median value for 2078 for Russia is according to the UN forecast of 127, 4 million people.
