United Nations released a new report regarding how the world population will look like in 33 years. The document reveals surprising changes in the demographic area. At the moment, there are 7.6 billion humans on Earth. However, this number will get to 9.8 billion by 2050 while in 2100 there are projected to be 11.2 billion.
Each Year, The World Population Increases by 83 Million
However, the levels of fertility are not even for the entire planet. While people have fewer children than before in general, the growth in population is accelerated by developing countries. According to World Population Prospects: the 2017 Revision, each year the number of people increases by approximately 83 million. The authors of the report at the UN Department of Economic and Social Affairs are convinced that the fast pace of growth would not be impaired by recent trends of fertility level decline.
As a consequence, there will be only 47 least developed countries that will contribute to population growth overall. In these parts of the world, the fertility rates point at 4.3 offspring per woman. This rhythm will increase the current estimations of one billion to 1.9 billion by 2050 per country. On top of that, the communities in 26 African nations have chances to double in 33 years.
Europe Holds the Lowest Fertility Rate
The European continent experiences the lowest birth rate in the world. In 2010-2015, the rate was 1.6 births per woman which is still higher than in 2000-2005 when the rate showed 1.4. By comparison, Africa recorded a rate of 4.7 births in 2010-2015 which is still lower than 2000-2005 when the average was 5.1 per woman. As a consequence, the federal republic of Nigeria will become the third most populous place in the world by 2050. At the moment, Nigeria is ranked the seventh.
The UN report tackled the issue of migration and Syrian refugees. From a demographic point of view, these fluctuations of people are helping regions with low fertility rates such as Europe to slow down the consequences of a population that starts an ageing process.
