The World’s Population

Parts of Kenya, Somalia, and Ethiopia are experiencing record-breaking drought affecting more than 47 million people. Torrential rains and floods in Libya displaced over 40,000 people, and parts of Bangladesh, India, and Thailand were scorched by record high temperatures.

As 2023 closes as perhaps the hottest year on record, more people are experiencing impacts from climate change, which can worsen food insecurity, displace people from their homes, and contribute to deaths. Population characteristics like age, gender, and socioeconomic status are a few of the factors that make some people more vulnerable to these effects. Understanding them can help countries adapt and build resilience to future climate-related events.

Globally, there were 8.7 million internally displaced persons due to disasters at the end of 2022, and 69% of those living in low-income countries were experiencing moderate to severe food insecurity. Ten percent of the world’s population was ages 65 and older, while 25% were under age 15. The global total fertility rate—or average lifetime births per woman—was 2.2, but this rate varied widely by region, ranging from 5.6 in Middle Africa to 1.1 in East Asia.
