Back in the 1960s, many scientists and policymakers feared the world was heading for disaster—not because of climate change or artificial intelligence, but because of too many people. Paul Ehrlich’s 1968 bestseller The Population Bomb warned of mass starvation and ecological collapse if human numbers weren’t brought under control. These fears shaped national policies, global aid, and even coercive sterilization programs in some countries. And the numbers did seem alarming. The global population rose from 3 billion in 1960 to 5 billion by 1987, then to 6 billion by 1999, and 8 billion by 2022. Since the mid‑1970s, we’ve been adding about 1 billion people every 12 years. The animated map below, created by VividMaps.com using World Bank data, shows how population changed in each country from 1960 to 2022: The map makes it clear: Asia has long led the world in population size, growing from about 1.7 billion in 1960 to 4.7 billion by 2022. Africa’s population grew even faster—up nearly six...
Ever wondered how long the average person lives these days—and what those years actually look like? Life expectancy isn’t just a number. It’s a mirror of how well a society supports its people—from access to clean water and doctors to education, air quality, and even peace. And the global story? It's been one of steady progress, despite a few hard-hitting setbacks. Between 2000 and 2019, the average life expectancy across the world rose from about 66.8 years to 73.1 years, according to the World Health Organization. That’s over six extra years in less than two decades. Pretty impressive, right? But then came COVID-19, which knocked that number back temporarily. Even so, most of the long-term gains have held strong. Meanwhile, something called healthy life expectancy—basically, how many of those years we live in good health—has also gone up. People aren't just living longer, they’re living better, too. Where People Live the Longest Some places seem to have cracked the code. Ti...
