Human Population Through Time

Human Population Modern humans evolved in Africa about 200,000
years ago. About 100,000 years ago, we began migrating
across the globe. Our population remained low—probably less
than 1 million people. With the advent of farming, growth picked up. By AD 1, world population reached approximately
170 million people. Year: AD 1

Human population: 1.7 b World Wars Year: 2015
Human population: 7.4 b Year: 2050
Human population (projected): 9.5 b LEVELING OFF If current trends continue, global populations will peak at 11 billion around 2100.

Growth is slowing because average fertility rates are falling in nearly every country. 1950: 5 babies/woman 2100: 2 babies/woman If fertility forecasts are slightly off, our peak population will peak lower…..or higher. It took 200,000 years for our population to reach 1 billion. And only 200 years to reach 7 billion. As our population has grown, so has our use of Earth's resources. Choices we make today family planning reduced consumption pollution controls habitat protection Choices we make today affect the future of our species—and all life on Earth..
