The World's Population

POPULATION GROWTH MAP ; m = million ; b = billionFor example: in North America, the population grew from 450.8 million in the year 2000 to 543.4 million in 2018. Our growing population The world's population is projected to continue growing for the next 50 to 60 years, peaking at approximately 10.3 billion by the mid-2080. After reaching this peak, it is expected to gradually decline to around 10.2 billion by the century's end. Currently, one in four people lives in a country where the population has already peaked.Fertility rates are declining, with women bearing, on average, one child less than in 1990, resulting in a global fertility rate of 2.3 live births per woman as of 2024. Life expectancy is on the rise again after the COVID-19 pandemic, reaching 73.3 years in 2024, with projections of 77.4 years by 2054. Notably, by 2080, the number of individuals aged 65 and older is expected to surpass that of children under 18, and by the mid-2030s, those aged 80 and over will outnumber infants. Day of Eight Billion Around November 15th, 2022, the world’s population reached 8 billion people, a milestone in human development. While it took the global population 12 years to grow from 7 to 8 billion, it will take approximately 15 years—until 2037— for it to reach 9 billion, a sign that the overall growth rate of the global population is slowing. Yet levels of fertility remain high in some countries. Countries with the highest fertility levels tend to be those with the lowest income per capita. Global population growth has therefore over time become increasingly concentrated among the world’s poorest countries, most of which are in sub-Saharan Africa. The world in 2100 While there is some uncertainty around the future size of the world’s population, the estimated likelihood that it will peak within the 21st century is 80 per cent, with the peak likely to occur sometime between the mid-2060s and 2100. The size of world’s population in 2100 is now expected to be 6 per cent smaller – or about 700 million people fewer – than anticipated a decade ago. The peak in the projected size of the global population is due to several factors including lower-than-expected levels of fertility observed in recent years in some of the world’s largest countries, particularly China, and slightly faster-than-anticipated fertility declines in some parts of sub-Saharan Africa. China (1.4 billion) and India (1.4 billion) remain the two most populous countries in the world.Immigration is projected to be the main driver of population growth in 52 countries and areas through 2054 and in 62 through 2100, including Australia, Canada and the United States of America.( taken from ) In which 3 countries is 'Immigration' projected to be the main driver of population growth?
