This data is based on the following sources
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 employ Lührmann et al.'s criteria and use a threshold of 0.8 to classify the original indicator (v2x_liberal*
) into two categories: 0 ("No") and 1 ("Yes").
While RoW covers the years since 1900, we use V-Dem's historical data from 1789 to 1899 to expand the classification's coverage back in time.
We expand the years covered by V-Dem further: To expand the time coverage of today's countries and include more of the period when they were still non-sovereign territories, we identified the historical entity they were a part of and used that regime's data whenever available
For example, V-Dem only provides regime data since Bangladesh's independence in 1971. There is, however, regime data for Pakistan and the colony of India, both of which the current territory of Bangladesh was a part. We, therefore, use the regime data of Pakistan for Bangladesh from 1947 to 1970, and the regime data of India from 1789 to 1946. We did so for all countries with a past or current population of more than one million.
