Share of population living in extreme poverty
What you should know about this indicator
- The ‘cost of basic needs’ approach was recommended by the World Bank Commission on Global Poverty, headed by Tony Atkinson, as a complementary method in measuring poverty.
- Moatsos describes the methodology as follows: “In this approach, poverty lines are calculated for every year and country separately, rather than using a single global line. The second step is to gather the necessary data to operationalize this approach alongside imputation methods in cases where not all the necessary data are available. The third step is to devise a method for aggregating countries’ poverty estimates on a global scale to account for countries that lack some of the relevant 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
From the share and number unable to meet basic needs available in the dataset, we can estimate the number below different "dollar a day" poverty lines. Additionally, we estimate the share and number above these poverty lines, as well between them. We also estimate the share and number of people able to meet basic needs.
