Share of population living in extreme poverty
What you should know about this indicator
- Extreme poverty here is defined as living below the International Poverty Line of $2.15 per day.
- The data is measured in international-$ at 2017 prices – this adjusts for inflation and for differences in the cost of living between countries.
- Depending on the country and year, the data relates to income measured after taxes and benefits, or to consumption, per capita. 'Per capita' means that the income of each household is attributed equally to each member of the household (including children).
- Non-market sources of income, including food grown by subsistence farmers for their own consumption, are taken into account.
- Regional and global estimates are extrapolated up until the year of the data release using GDP growth estimates and forecasts. For more details about the methodology, please refer to the World Bank PIP documentation.
Frequently Asked Questions
What is the International Poverty Line and how is it set?
There is no single definition of poverty. Our understanding of the extent of poverty and how it is changing depends on which definition we have in mind.
What are international-$ and why are they used to measure incomes?
Much of the economic data we use to understand the world – for instance on the goods and services bought or produced by households, firms and governments, or the incomes they receive – is initially recorded in terms of the units in which these transactions took place. That means this data starts out being expressed in a variety of local currencies – as so many rupees, US dollars, or yuan, etc. – and without adjusting for inflation over time. This is known as being in ‘current prices’, or in ‘nominal’ terms.
How comparable is the World Bank data on household incomes across time or between countries?
Because there is no global survey of incomes, researchers need to rely on available national surveys. Such surveys are designed with cross-country comparability in mind, but because the surveys reflect the circumstances and priorities of individual countries at the time of the survey, there are some important differences. In collating this survey data the World Bank takes steps to harmonize it where possible, but comparability issues remain.
How does the World Bank produce global and regional estimates of poverty and inequality from national data?

How we process data at Our World in Data
All data and visualizations on Our World in Data rely on data sourced from one or several original data providers. Preparing this original data involves several processing steps. Depending on the data, this can include standardizing country names and world region definitions, converting units, calculating derived indicators such as per capita measures, as well as adding or adapting metadata such as the name or the description given to an indicator.
At the link below you can find a detailed description of the structure of our data pipeline, including links to all the code used to prepare data across Our World in Data.
Notes on our processing step for this indicator
For most countries in the PIP dataset, estimates relate to either disposable income or consumption, for all available years. A number of countries, however, have a mix of income and consumption data points, with both data types sometimes available for particular years.
In most of our charts, we present the data with some data points dropped in order to present single series for each country. This allows us to make readable visualizations that combine multiple countries and metrics. In choosing which data points to drop, we try to strike a balance between maintaining comparability over time and showing as long a time series as possible. As such, the exact approach varies somewhat across countries.
If you would like to see the original data with all available income and consumption data points shown separately, you can do so in our Poverty Data Explorer. You can also download this data in our complete dataset of the World Bank PIP data.
