The world's population (which sits at 7.7 billion) will hit 10.9 billion at the century's end, according to estimates from a new UN report, but rates of growth will diminish by 2100 and world population could begin to plateau due to low fertility rates. The bad news: Until then, rapid growth will continue to put a strain on countries and pose a hurdle in meeting the UN's Sustainable Development Goals. India is set to overtake China as the world's most populous country by around 2027, sub-Saharan Africa is the only region that figures to sustain rapid population growth through 2100, and the world is getting older, the study finds, reporting that people aged 65 and older outnumbered children under five for the first time ever in 2018. The graph below (taken from the report) shows total population and growth rates: Taking immigration flows into account, the map below shows which countries will see boosts due to both natural population increases and new immigrants arriving: |
