"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.Related post:
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.”
"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."
"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."
"As of September, more than half the world—3.8 billion people—are middle-class or rich, Homi Kharas of the Brookings Institution and Kristofer Hamel of World Data Lab found. They define middle class as consuming between $11 and $110 a day, in 2011 dollars adjusted for varying costs between countries."
