Sources and processing

This data is based on the following sources

The State Capacity Dataset seeks to fill a gap in comparative, cross-national research by providing researchers with a measure that captures the multidimensionality of the concept and is distinct from other concepts of interest such as economic development or regime type. Version 1 of the dataset covers the years 1960-2015 for 177 countries.

The methodology for the state capacity estimates is described in "Leviathan's Latent Dimensions: Measuring State Capacity for Comparative Political Research." Additional documentation is provided in the online appendix associated with the article.

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.
