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
- We have extracted the data from the official Equaldex JSON API.
- We combine the historical and current data extracted from the API to create a time series.
- Whenever policy implementation dates for a status are not provided in the data, and this status is the only available for the country, we consider that this status has not changed during the entire period of the dataset.
- We group some of the categories the source has defined for each issue, for further clarity in our visualizations.
- We present this data only for sovereign states, defined by Butcher and Griffiths (2020). We use the definitions of the latest year available.
Reuse this work
- All data produced by third-party providers and made available by Our World in Data are subject to the license terms from the original providers. Our work would not be possible without the data providers we rely on, so we ask you to always cite them appropriately (see below). This is crucial to allow data providers to continue doing their work, enhancing, maintaining and updating valuable data.
