Legislative checks on government

How this is measured

Whether the legislature questions officials in practice, has the capacity to investigate the executive, and whether other oversight bodies do so. Countries without a functioning legislature are coded at the bottom of the scale rather than left blank, so the index runs continuously through periods of direct rule. Because it is coded by country experts and then put through a measurement model, every value is an estimate with a credible interval around it. V-Dem publishes those intervals; this site shows only the point estimate, so how firm any single number is cannot be read off the screen. The intervals are wider where fewer experts coded a country and in the earlier centuries, which is exactly where the long series is most tempting to read closely.

157 countries and territories have a figure for 2025. This is the most recent year the series covers well; the viewer holds every year from 1789.
