  • V-Dem

    V-Dem provides the most comprehensive global dataset on democracy: 350 indicators and indices on a variety of important aspects of democracy! The data cover 173 countries.  Here we offer a tour on using the Online Analysis Tool.

  • Generating a Graph

    Step 1: Select an indicator.

    Step 2: Select one or several countries/regions.

    Step 3: Adjust the year range.

    Step 4: To produce the graph, press ‘Generate Graph’.

  • Drilling-Down Function

    To see each of the constituent components of an index, use a drill-down function. 

    Click on an index's line in a graph to activate this drill-down function. You can select and unselect which of the components you want to view by clicking on the text labels on the right-hand side of the graph.

  • Confidence Intervals

    V-Dem data are based on the reports of multiple coders, who sometimes diverge in their ratings. In order to deal with such divergences, we provide confidence intervals about the estimated values of each index. The confidence is illustrated by shadows above and below the lines. Larger intervals indicate greater uncertainty about the estimate.

  • Interpreting Graphs

    We display details regarding the construction of V-Dem indicators and indices in the "Selected Indicators" box at the bottom of the page.

    Tip! The V-Dem Codebook includes a table entitled ‘Structure of Aggregations – All Indices and Indicators’. This table displays how indicators, components and indices are related, which is helpful for understanding the structure of aggregation.

  • Saving a Graph

    You can save a graph by clicking on the "download" at the upper right-hand side of the graph, then selecting your preferred format.

  • Tip!

    You can hide the menu for the selection of countries and indicators by pressing the arrow in the top right corner of the box.
