Drawing from a large dataset of the characteristics of historical constitutions, scholars at the Comparative Constitutions Project have developed a set of indices that describe the content of world constitutions. 

Use the map below, which can be redrawn as a grid to eliminate the visual bias introduced by landmass, to explore the indices in countries across the globe. Learn more about the constituent elements of each of the indices here. And find individual country pages, with more visualizations, below.  Try Chile, for example.
