Sources and processing

This data is based on the following sources

Scheffers et al. – Global wildlife trade across the tree of life

Scheffers et al. (2019) quantify the number and share of vertebrate species that are traded, either locally, nationally or internationally.

This data is also available, broken down by the share of traded species that are used as pets or as products (such as for meat, medicines, body parts, trophy hunts etc.). Note these shares may sum to more than 100% since many species are traded as both pets and for their products.

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.
