Poverty gap index at $2.15 per day
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.

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.
