Right now there are 7.5 billion people on Earth and counting. But the world in 2050 will be even more packed, according to new United Nations (UN) projections. The new World Population Prospects: 2017 Revision report estimates that there could be nearly 10 billion people on the planet in a little over 30 years.
By 2030, the global population could be 8.6 billion, according to the UN. 9.8 billion people might reside on Earth in 2050, and 11.2 billion in 2100. As around 83 million people are born every single year, the organization expects the total population to rise even if fertility levels go down. And while China currently has the most people of any country, the UN estimates India will surpass China in around seven years.

Of the world’s 10 largest countries, Nigeria is growing the fastest. The country is currently the world’s seventh largest but the UN estimates they will surpass the United States to become the world’s third largest country just before 2050. And between now and 2050, around half of all the population growth on Earth will be centered in only nine countries: Nigeria, India, the Democratic Republic of the Congo, Ethiopia, Tanzania, Uganda, Indonesia, Pakistan, and the United States.
The new report doesn’t just cover the amount of people in the world. It addresses fertility, life expectancy, and refugee movement. For example, fertility has fallen in almost all the areas of the world, even in Africa. One exception is Europe. A reduction in fertility has led to an aging population. Meanwhile life expectancy has risen globally from 65 to 69 years for men and 69 to 73 years for women, although the UN noted large disparities between countries in those figures.
The UN Department of Economic and Social Affairs, Population Division put out the June 21 report. The organization says the statistics could help agencies better work to achieve the Sustainable Development Goals.
