This video shows the global population change from 1800 to 2100. What I find interesting is the religious makeup of the most populous countries by 2100. Christianity is the majority in 4 of the top 10 – the US, Congo, Ethiopia, and Tanzania.
Percent of Christians in the 10 most populous countries (using 2022 data):
- India – 2.3%
- China – 2.5%
- Nigeria – 45.9%
- US – 64%
- Pakistan – 1.27%
- DRC – 95%
- Indonesia – 10.7%
- Ethiopia – 67%
- Tanzania – 63%
