Falling birth rates and aging populations pose risks to global economies
What the chart shows
This chart shows the expected change in fertility rates (the average number of births per woman) for various regions and countries since 1960. The red dots depict the rate in 1960, while the blue dots represent World Bank forecasts for 2024.
We can see a significant decline globally, from 4.7 to 2.3, with countries such as Iran, Brazil and South Korea experiencing the biggest decrease. Many of these countries now have a total fertility rate (TFR) of less than 2.1, the replacement level for maintaining a stable population in most developed countries. (Nearly half of the global population lives in countries where the TFR is already below 2.1, according to {{nofollow}}data from the UN.)
Behind the data
Global population growth is becoming more concentrated, with more than half of the projected increase between 2022 and 2050 expected to come from just eight countries: the Democratic Republic of the Congo [DRC], Egypt, Ethiopia, India, Nigeria, Pakistan, the Philippines and the United Republic of Tanzania, according to the UN.
With people living longer as birth rates decline, the implications are profound. Countries with declining fertility rates must adapt their retirement systems, healthcare and labour markets to support an aging population, while countries experiencing higher population growth need sustainable development, education investment and infrastructure to support young populations and drive economic growth.
