A century of world population trends: 1950 to 2050

Today, the world’s population is more than three times larger than it was in the mid-twentieth century. The global human population will reach 8.0 billion in mid-November 2022 from an estimated 2.5 billion people in 1950, adding 1 billion people since 2010 and 2 billion since 1998. It took around 37 years since 1950 for human numbers to double, surpassing 5 billion inhabitants in 1987. Thereafter, it is estimated that more than 70 years will be required for the global population to double again, rising to over 10 billion by 2059 (Part III).
