Indicator generated from democracy_femalesuffrage:. This adjusts democracy by also requiring that at least half of adult women have the right to vote. Thirty countries have changed values.

Sources and processing

This data is based on the following sources

This dataset covers all sovereign countries (including micro-states) from 1800 to 2020. Generally, we use United Nations membership to define when micro-states enter the data set. We thank Benjamin A.T. Graham and his students at USC (Valeria Flores-Cadena, Jiaming Shi, Affan Rahman, and Apurvi Bhartia) for providing their own democracy ratings and supporting information as part of a class project.

The authors argue that their measure’s distinguishing features—a concrete, dichotomous coding and a long time span—are of critical value to empirical work on democracy. Inspired by Robert Dahl, they define a country as democratic if it satisfies conditions for both contestation and participation. Specifically, democracies feature political leaders chosen through free and fair elections and satisfy a threshold value of suffrage.

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.
