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.
Rolling averages by decade have been calculated for the original estimates before 1981, to address uncertainty in the data.
