The Remarkable Fall in Global Poverty

The Remarkable Fall in Global Poverty

Timothy Taylor 24/10/2018 8

Back in 1990, the World Bank defined an "absolute poverty" line. It was based on the actual poverty lines as chosen by the governments of low-income countries around the world, and thus can be taken to represent those people who are beneath the most basic minimums for basic necessities like food, shelter, and clothing. This poverty line has been updated over time to adjust for changes in prices and exchange rates, and currently stands at $1.90 in consumption per person per day. The World Bank provides an overview of global poverty in its annual "Poverty and Shared Prosperity" report for 2018, titled "Piecing Together the Poverty Puzzle." Here are some points that caught my eye.

The world has seen a dramatic fall in absolute poverty in the last 30 years or so. In 1990, more than one-third of the world's population was below the absolute poverty line; by 2015, it was 10% and falling. The raw number of people below the absolute poverty line declined by more than 1 billion. This extraordinarily rapid rise in the economic well-being of the world's poorest is without historical precedent.


A breakdown of the data by region shows an unsurprising pattern. Poverty in the east Asian region has dropped dramatically, thanks in substantial part to economic growth in China. Poverty in the south Asian region has dropped dramatically, thanks in substantial part to growth in India, as well as Bangladesh and others. Poverty rates in sub-Saharan Africa remain high.

But poverty rates don't quite capture the entire story. Population levels are very high in China and India, so that even low rates of poverty in those countries implies large absolute numbers of poor. Indeed, one pattern that has emerged is that in absolute numbers, more of the world's absolute poor now live in middle-income countries (which includes China, India, Pakistan, Bangladesh, Indonesia and others) than in low-income countries.

The report includes chapters looking at other measures of need, like improving the economic status of the bottom 40% of the population, or a multidimensional measure of poverty that includes not just income but access to health care and a secure community, or measures of poverty focused especially on women and children.

The World Bank also defines a poverty line for low-middle-income countries of $3.20 in consumption per person per day, and a poverty line for upper-middle-income countries of $5.50 per person per day. The share of people below these poverty lines has also fallen dramatically, although they remain fearsomely high in the regions of South Asian and sub-Saharan Africa.

    The biggest reason why there is so much poverty in Asia and Africa is because of corruption.

  • Alex Mcdonald

    Stop pillaging Africa for natural resources so their governments can afford infrastructure.

  • Nathan Webstar

    Let the poorest nations be more free and leave capitalism do its magic.

  • Matt Stratton

    A great explanation of a difficult social issue.

  • Joe Cleghorn

    The best help is through sterilization. If it's paid for that, it would be better and fair.

  • Gary Andrews

    There is no balance. A lot of things are needed. People need to change their mindsets as well.

  • Ian Bennett

    We could help poor nations economically but if their politicians do not care about poverty it will be all useless.

  • Sameer

    The information is dated. Much has changed between 2015 and 2018. The low-income countries now again contain the largest number of extreme poor. Sub-saharan now is home to more than 65% of the world's extreme poor.
