According to a an article in The Guardian, The best news in the world, by the president of the World Bank, Jim Yong Kim, there has been a dramatic fall in global poverty over the past two decades. The number of people in extreme poverty is projected to fall this year to below 10% of global population for the first time. This has been made possible, he claims, by unprecedented economic growth, especially in China.
But this raises three questions.
The first is whether, in the face of falling growth rates, progress in poverty reduction can be maintained.
The second is whether the World Bank is measuring extreme poverty in the right way. It is now defined as living on less than US$1.90 a day in 2011 prices – until a few weeks ago is was $1.25 in 2005 prices. As a result of this rebasing, global poverty falls from 14.5% of the world’s population (or 1011 million people) under the old method to 14.2% (or 987 million) under the new.
The third question is whether countries can improve their data collection so that a truer estimate of poverty can be made.
As far as the first question is concerned, Kim states that to stimulate growth, ‘every dollar of public spending should be scrutinised for impact. Every effort must be made to improve productivity.’ What is more, three things must happen:
• Economic growth must lift all people. It must be inclusive. • Investment in human beings is crucial – especially investing in their health and education. Malnourished and poorly educated children will never reach their full potential and countries, in turn, will fall short of their economic and social aspirations. • We must ensure that we can provide safety nets that prevent people from falling back into poverty because of poor health, economic shocks, or natural disasters.
As far as the second question is concerned, there are many who argue that $1.90 per day is far too low a measure of the extreme poverty threshold. It is a purchasing-power parity measure and is equivalent to what $1.90 would buy in the USA in 2011. But, according to the Jason Hickel article linked below, ‘the US Department of Agriculture calculates that in 2011 the very minimum necessary to buy sufficient food was $5.04 per day. And that’s not taking account of other requirements for survival, such as shelter and clothing.’ Peter Edward of Newcastle University, claims Hickell, ‘calculates that in order to achieve normal human life expectancy of just over 70 years, people need roughly 2.7 to 3.9 times the existing poverty line.’
But even if living on below $1.90 a day is defined as extreme poverty, it is important not to see the problem of poverty as having been solved for people who manage to achieve an income slightly above that level.
The third question is how to improve data. There is a paucity and unreliability of data in many developing countries. According to Kim:
Our report adds that data is sparse and inconsistent across the region and globally. Some 29 countries around the world had no poverty data from 2002 to 2011, so they could not track their progress. Another 28 had just one survey that collected poverty data during that time.
This is a situation that must change to improve the world’s ability to tackle poverty. In fact, we can’t accomplish our goal if we do not have enough information to know whether people are actually lifting themselves out of poverty. For that we need to address huge data gaps. We need robust data.

Ending extreme poverty and sharing prosperity: progress and policies World Bank, Marcio Cruz, James Foster, Bryce Quillin and Philip Schellekens (October 2015)
- Explain how the World Bank calculates the extreme poverty line.
- Why, if the line has risen from $1.25 per day to $1.90 per day, has the number of people recorded as being in extreme poverty fallen as a result?
- Why has the number of people in extreme poverty been rising over the years and yet the percentage of people in extreme poverty been falling?
- What policies can be adopted to tackle poverty? Discuss their practicality?
- Are reduced poverty and increased economic growth consistent policy goals? (See the blog post Inequality and economic growth.)
- What are the inadequacies of using income per day (albeit in ppp terms) as a measure of the degree of poverty? What other indicators of poverty could be used and how suitable would they be?
- How could international trade be made to work for the world’s poorest?
