Demography [New] Fertility rates are expected to fall worldwide, to the point where no country is expected to have fertility of more than five births per woman by 2050. Japan is only expected to have 100 million people in 2050, down from 125 million now, and South Korea, Germany and Russia are all expected to lose 10% of their populations by then. As native-born Americans have fewer and fewer children, immigration will provide the main source of population growth in the decades ahead. Central Africa, the second poorest region, is projected to experience the most rapid growth in the working age population over 2013-63, with an average annual growth rate of 2.8 percent. Countries around the world continue to undergo rapid demographic change: The global population is expected to grow by 3.1 billion between 2013 and 2063, 2.9 billion (92 percent) of them in just two regions: Asia and Africa. The populations of 55 countries or areas are projected to decrease by one per cent or more between 2019 and 2050 because of sustained low levels of fertility, and, in some places, high rates of emigration. The high fertility rates south of the Sahara mean that region of Africa will account for more than half of global population growth between now and 2050. In 2018, the child population was 73.8 million strong, accounting for 22.4% of the total U.S. population: With little change in the number of children expected through 2020, industry players must engage kids earlier and retain relationships through the teen years to realize full market potential. Between now and 2050, Africa is projected to experience the fastest rate of urban growth in the world, with the population of its cities set to absorb an additional 950 million inhabitants, and will reach a level of urbanisation of 60%. Global fertility is projected to reach a level around 2.1 births per woman by the 2060s Between 1994 and 2019, the total fertility rate fell from 2.9 to 2.5 births per woman. The global fertility rate is expected to be 1.9 births per woman by 2100, down from 2.5 today. For the first time in modern history, the world's population is expected to virtually stop growing by the end of this century, due in large part to falling global fertility rates. The rate of growth in the foreign-born population is projected to be more than twice the 24 percent increase in the overall US population by 2060. Fertility rates are expected to rise slightly until 2050, moving from 1.6 to 1.8 births per woman, but well below the natural replacement level of about 2.1. The rapid population growth is expected to continue into 2050, fueled by increased life expectancy and declining mortality and high fertility rates associated with a largely youthful - and booming - population. In 2050, India and China are slated to be the world's population giants, but the fastest growing populations will be in Sub-Saharan Africa. Based on the level of immigration the Census Bureau expects, the U.S. population will be 79 million people larger in 2060 than in 2017. The Census Bureau projects that future net immigration will total 46 million by 2060 and the total U.S. population will reach 404 million - 79 million larger than in 2017. Sub-Saharan Africa and South East Asia will see massive population growth by 2030, adding to the pressures on food production in the face of climate change. Climate change will increase disruption to network affecting the ability of the population to access active travel options. The total population of Japan is now expected to drop from 126 million in 2019 to 107 million in 2050, with some estimates projecting that number going as low as 87 million by 2060. The UK's population structure is expected to change considerably in the coming decades: The 65+ population is projected to grow by around 50% in both urban and rural areas between 2016 and 2039. Even though Africa will have many more older people, in 2050 it will still have a young and expanding population because of a very high fertility rate, at around 4.4 births per women.
