The World Is Getting Quietly, Relentlessly Better
By Greg Ip
For most of recorded history humanity lived on the brink of starvation. As recently as 1980 nearly half the world lived in “extreme poverty,” that is, consuming less than the basic necessities, which the World Bank values at $1.90 a day in 2011 dollars, adjusted for the differing costs of goods and services between countries. The proportion of people in extreme poverty was projected to fall to an estimated 8.6% last year and, given the correlation between growth and poverty, is almost certain to drop further this year.
Rising incomes alone cannot capture how much better life has gotten. “Nathan Rothschild was surely the richest man in the world when he died in 1836,” economists Max Roser and Esteban Ortiz-Ospina wrote in 2017. “But the cause of his death was an infection—a condition that can now be treated with antibiotics sold for less than a couple of cents. Today, only the very poorest people in the world would die in the way that the richest man of the 19th century died.”
Mr. Roser is the founder of Our World in Data, a website that tracks the evolution of human welfare over the last few centuries. Scroll through the charts, articles and data sets, and you will be stunned by how much better life has become in just the last few decades: Child mortality, illiteracy and deaths from violence have all plummeted, and life expectancy has gone up.
The world first eradicated a disease, smallpox, in 1980. It could soon eradicate a few more: 2016 saw just 46 new cases of paralytic polio recorded; in 2017, there were just 25 new infections of Guinea worm, a painful and disabling parasitic infection. These victories come not through laboratory breakthroughs but the meticulous application of tried-and-true tools, such as vaccination and improved sanitation.
Much of the decline in poverty happened in China, where per-person income has risen 25-fold since China’s then-leader Deng Xiaoping inaugurated its economic reforms in 1978. India‘s economy, though, is now growing faster than China’s. If India can maintain its pace, the impact on global well-being will be just as momentous, given that India’s population should soon pass China’s.
As with disease, poverty is being eradicated not through technological miracles but basic rules of growth: Invest more in your human and physical capital, open yourself to markets and trade—that’s right, globalization is good—and incomes will rise.
