The Online Analysis Tools were specially designed for V-Dem data. They allow users to analyze almost 400 indicators and indices of democracy in 173 countries. The reliable, precise nature of the indicators as well as their lengthy historical coverage should be useful not just to scholars studying why democracy succeeds or fails, but also to governments and NGOs.

The V-Dem Online Analysis is composed of following tools:


Variable Graph
This tool is used to compare multiple countries for one index or one variable at a time.

Choose a single question and compare multiple country results. Data are aggregated by year. The texts of the question and the responses are also displayed.


Country Graph

This tool can be used to display multiple variables and/or indices for one country over time.

Choose a single country and compare multiple question results. Data are aggregated by year. The text of the questions (but not responses) appears when you mouse over the question name in the "available questions" menu.

Motion Chart
This tool enables users to explore how the relationship between two variables changes over time.

Explore relationships between variables with this animated scatterplot, which uses colors to identify regions and size to represent national populations. Menus on the X and Y axes allow you to compare any of our 21 most general indices. The Play button reveals how the relationship has evolved historically. Use "control-+" if you want to make the chart larger in your window.

(This version of Motion Chart was created with a technical help from Brandon Greenawalt at Notre Dame's Center for Social Research)

Maps (Under development)
Create a color-coded map to view the distribution of scores around the world for one question in one year.


Using the interfaces above you can generate line graphs, maps, and animated scatterplots of the data for selected countries.

The line graphs are interactive in several respects:

  • Click on a series or country in the legend to toggle its line on and off.
  • Mouse over the lines and a list of scores for that year pops up.
  • Click and drag a range of years inside the graph to zoom in chronologically.
  • The menu in the upper-left corner enables you to save the image in various formats.

These tools work in most browsers, including Internet Explorer 9 and later. However, it may be necessary first to clear the cache, download history, and browser history. Proper functioning is not guaranteed on the Windows operating systems that Microsoft no longer supports, such as Windows XP or Vista. To save images in IE 10, right-click on the graph and "save as" an image file instead of using the upper-right menu.

The scores displayed in these graphs are summaries of ratings assigned by up to five country experts in our online surveys.
The process of data checking and data cleaning continues. Please use the contact form below to tell us if you find apparent errors in the indicators or indices in the V-Dem dataset.
