We measure all civil and political rights using a survey of in-country human rights experts. We ask questions about the frequency of violations of each right, then combine the answers with a statistical model that means we can compare responses across countries, and over time.
We then show the results as an estimated score out of 10, within an uncertainty band.
We also ask the in-country experts about who is at particular risk of human rights abuses. We show information based on their responses on the 'People at risk' tab on the country pages.
