The world population, which has increased by 1 billion in the last 12 years, hit 8 billion people on Tuesday. India is expected to overtake China as the most populated nation by the end of next year. According to CBS News, the milestone of 8 billion people on the planet has long-term importance for both wealthy and developing nations. As a result of improvements in health, the world’s population has increased from 7 billion to 8 billion since 2010, whereas it took hundreds of thousands of years for it to reach 1 billion.
However, population growth has slowed compared to previous periods, and the United Nations warns that the challenges of feeding, housing, and preventing people from polluting the environment will be significant as the world’s population is predicted to increase to more than 10 billion over the next 60 years. Additionally, life expectancy worldwide climbed to approximately 73 years and is projected to reach 77 years by 2050. The U.N.’s demographic report also showed that men currently outnumber women by a small margin, but that will likely level out by 2050 as well.
Even as the world surpasses the 8 billion milestone, the population growth rate is at its lowest level since 1950, with less than 1% growth in the population since 2020. The U.N. analysis predicts there will be 8.5 billion people in 2030, 9.7 billion in 2050, peaking at 10.4 billion in the 2080s, and remain the same until 2100.
