  • 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.

  • Variable Graph

    This tool compares multiple countries for one indicator/or index. Select one indicator and multiple countries/regions. The data are aggregated by year.

  • Generating a Graph

    Step 1: Select an indicator/index.
    Step 2: Select one or several countries/regions.
    Step 3: Adjust the year range.
  • Drilling-Down Function

    An index is constructed by indicators and components, the former is the lowest level of aggregation while components are sub-indices. The drilling-down function makes it possible to explore the indicators/components included in an index while keeping the index in view. Double-click on an index's line to drill-down. You can select or unselect indicators/components you want to view by clicking on the text labels to the right.

  • Confidence Intervals

    V-Dem data are based on the scores 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 colored shadows around the lines. Larger intervals indicate greater uncertainty about the estimate.

  • Interpreting Graphs

    Details about selected indicators and indices are available in the "Selected Indicators" box at the bottom of the page.

    Tip! The V-Dem Codebook includes the appendix ‘Structure of Aggregations – All Indices and Indicators’, which illustrates how indicators, components and indices are constructed and related.

  • Relative and Original Scales

    The data can be plotted in ‘relative’ or ‘original scale’. When using the default setting of ‘relative scale’ option, all indicators are rescaled allowing for comparisons, even if their initial scale is different. Indicators on their original scales can be viewed using the ‘original scale’ option.

    Tip! When viewing many indicators in the ‘relative option’, you can view the original scale for one indicator at a time simply by ticking the box next to the indicator.

  • Saving a Graph

    Save a graph by clicking on the download sign (three-line sign) at the upper right-hand side of the graph, then select your preferred format (png, jpeg, pdf, svg). You can also export the data to a csv file. The csv file includes the original scaled numbers regardless of whether original or relative is selected.
