High, medium, and low projections of the future human world population [1]. In world demographics, the world population is the total number of humans currently alive. It was estimated by the United Nations to have exceeded eight billion in mid-November 2022.
The global population is expanding rapidly thanks to major advances in public health, but can the Earth sustain so many humans?
[3] [4] Old estimates put the global population at 9 billion by 2037–2046, 14 years after 8 billion, and 10 billion by 2054–2071, 17 years after 9 billion; however these milestones are likely to be reached far sooner.
Global population size, estimates (1950–2022) and medium scenario with 95 percent prediction intervals, 2022–2100 [4]. Amid global challenges such as climate change and the COVID-19 pandemic, several observers, including David Attenborough, have expressed concerns about the future of the planet and its inhabitants as the population grows.
Absolute increase in global human population per year [1] Population growth is the increase in the number of people in a population or dispersed group. Actual global human population growth amounts to around 83 million annually, or 1.1% per year. [2] The global population has grown from 1 billion in 1800 to 8.1 billion in 2024. [3]
Earth has a human population of over 8 billion as of 2024, with an overall population density of 50 people per km 2 (130 per sq. mile). Nearly 60% of the world's population lives in Asia, with more than 2.8 billion in the countries of India and China combined. The percentage shares of China, India and rest of South Asia of the world population ...
