The world’s current population of 7.7 billion is only 7% of all people who have ever lived, with over 108 billion people having roamed the Earth since modern humans appeared. Life expectancy has significantly increased, and by 2050, the world is predicted to have added 5 billion people. The average age of the world’s population is 30, and every second, 4.2 people are born and 1.8 people die.
As you read this, there are approximately 7.7 billion other people on the planet with you. That might sound like a lot, but look at it this way and your perspective might change: The world’s current population is only about 7% of all people who have ever lived. According to the Population Reference Bureau, which updates its statistics regularly, more than 108 billion people have roamed the Earth since behaviorally and anatomically modern humans first appeared about 50,000 years ago. The office acknowledges that much of its work is based on speculation, since there is no accurate data for 99 percent of the time humanity has existed, but the figures can be approximated by looking at how long humans have existed. ‘Homo sapiens and the average population size at different times. Looking ahead, the office predicts that by 2050, the world will have added about 5 billion people. If those numbers make you feel small, keep in mind that you’re enjoying a much longer life than previous generations. “Life expectancy at birth probably averaged only about 10 years for most of human history,” the office reports. “For example, estimates of average life expectancy in Iron Age France (c. 800 BC to AD 100) have been put at just 10 or 12 years.”
A world of information:
The average age of the world’s population is 30, which means that around half of people are over 30 and half are under 30.
By 2050, there will be an estimated 425 million people aged 80 and over; that figure is expected to more than double by 2100.
With every second that passes, about 4.2 people are born and 1.8 people die.
