Fall of extreme global poverty
fastest fall 1990–2019· Event· Society: who gained, who lost
Mostly agreedGood evidence; some details uncertain.
The share of people in extreme poverty fell from over a third of humanity in 1990 to under a tenth by 2019.
See it on the Innovation & Wealth map →What happened
The World Bank's extreme-poverty line was $2.15 a day (2017 prices), raised to $3.00 in 2025, which raises the counts. By its estimates, the share fell from about 38% of the world, roughly 2 billion people, in 1990 to about 9%, around 700 million, in 2019. China accounted for most of the drop, with India, Vietnam and Indonesia also major contributors. COVID-19 stalled progress in 2020, and extreme poverty is now concentrated in sub-Saharan Africa.
Impact on society and the economy
It is probably the largest rise in living standards in history, driven mainly by market reforms, trade and factory jobs in Asia.
How we know
Household surveys compiled by the World Bank's Poverty and Inequality Platform, plus long-run estimates by economists such as Bourguignon and Morrisson and Our World in Data.
Still debated
Critics such as Jason Hickel say $2.15 a day is too low a bar; by higher lines progress is slower. Credit split between trade and domestic policy is debated.
Connections (4)
▸The Industrial Revolution began the escape from poverty seen in Fall of extreme global povertyMostly agreed
The connection
Before about 1800, most people everywhere lived near bare subsistence. Machine power and factories let output per person grow steadily for the first time, first in Britain, then Europe and North America. The late-20th-century fall in poverty was largely the same process, industry, cities and factory jobs, reaching China, India and other poor countries.
When and how
Britain from about 1760; spread through the 1800s to Europe, the US and Japan; reached East Asia after 1950 and China after 1978.
How sure are we?
Long-run income estimates from the Maddison Project and World Bank poverty data show near-flat incomes before 1800 and sustained growth wherever industry spread.
Debates
Why industry took nearly two centuries to reach most of the world, whether because of colonialism, institutions, geography or policy, is one of economics' biggest debates.
▸Malthus and the population trap was disproved in the long run by Fall of extreme global povertyMostly agreed
The connection
Malthus argued in 1798 that population grows faster than food, so incomes would always be pushed back to bare survival. Instead, world population has grown about eightfold since 1800 while extreme poverty fell from most people to under a tenth, thanks to farm and factory productivity and, later, falling birth rates.
When and how
England, 1798, in An Essay on the Principle of Population; the escape became clear worldwide in the 1900s, helped by the Green Revolution in crops from the 1960s.
How sure are we?
Population and food-output data, and World Bank poverty figures, show food and incomes outpacing population almost everywhere since 1800.
Debates
Malthus described history before 1800 fairly well; some ecologists argue his limits could return through climate change and resource strain, while most economists doubt it.
▸East Asian economic miracles were an early part of Fall of extreme global povertyMostly agreed
The connection
Japan, then South Korea, Taiwan, Hong Kong and Singapore, then Southeast Asia and China, grew fast by investing heavily, educating workers and exporting. Each wave moved millions from farms into factory jobs. East Asia went from the region with the most extremely poor people in 1990 to one of the least poor, accounting for most of the global decline.
When and how
Japan from the 1950s; the 'Four Tigers' from the 1960s; China from 1978; Vietnam from its 1986 Doi Moi reforms.
How sure are we?
World Bank regional poverty data and its 1993 report 'The East Asian Miracle' document the growth and the poverty decline.
Debates
Whether the miracle came from free markets or heavy state guidance, and whether poor countries can copy it as factory automation spreads, is debated.
▸Deng Xiaoping's reform and opening drove much of Fall of extreme global povertyMostly agreed
The connection
Freed to farm their own plots and later to move to city factory jobs, hundreds of millions of Chinese rose out of extreme poverty. By World Bank estimates, close to 800 million Chinese left extreme poverty between 1978 and the late 2010s, about three-quarters of the world's reduction in that period.
When and how
Rural China first, with household farming from 1978, then coastal factory cities. China declared extreme poverty eliminated in 2021 by its own standard.
How sure are we?
World Bank and Chinese household survey data; a 2022 joint World Bank–Chinese government report gives the 800 million figure.
Debates
Some question China's official statistics and its 2021 claim; others debate how much credit goes to markets versus state investment.
