The World Justice Project (WJP) Rule of Law Index® provides original, impartial data on how the rule of law is experienced by the general public in 102 countries around the globe.
The WJP Rule of Law Index 2015 relies on over 100,000 household and 2,400 expert surveys to measure how the rule of law is experienced in practical, everyday situations by ordinary people around the world. Performance is assessed using 44 indicators across 8 categories, each of which is scored and ranked globally and against regional and income peers: Constraints on Government Powers, Absence of Corruption, Open Government, Fundamental Rights, Order and Security, Regulatory Enforcement, Civil Justice, and Criminal Justice.
The WJP Rule of Law Index is the most comprehensive index of its kind and the only to rely solely on primary data. The Index’s scores are built from the assessments of local residents (1,000 respondents per country) and local legal experts, ensuring that the findings reflect the conditions experienced by the population, including marginalized sectors of society.
- New data for 2015: Updated scores and rankings for 102 countries across 8 primary rule of law indicators and 47 sub-factors.
- Data app: In-depth country data featured on a standalone site for quickly accessing, comparing, and downloading WJP Rule of Law Index data.
- Changes over time: Country profiles feature changes in rule of law adherence over time.
- New global insights: Global insights into impunity, open government, policing perceptions, and more.
- Additional countries: New to the WJP Rule of Law Index — Belize, Costa Rica, and Honduras.
The WJP Rule of Law Index relies on over 100,000 household and expert surveys to measure how the rule of law is experienced in everyday life around the world. Performance is assessed through 44 indicators organized around 8 themes: constraints on government powers, absence of corruption, open government, fundamental rights, order and security, regulatory enforcement, civil justice, and criminal justice.
The production of the WJP Rule of Law Index® may be summarized in eleven steps:
- The WJP developed the conceptual framework summarized in the Index’s 9 factors and 47 sub-factors, in consultation with academics, practitioners, and community leaders from around the world.
- The Index team developed a set of five questionnaires based on the Index’s conceptual framework, to be administered to experts and the general public. Questionnaires were translated into several languages and adapted to reflect commonly used terms and expressions.
- The team identified, on average, more than 300 potential local experts per country to respond to the experts’ questionnaires, and engaged the services of leading local polling companies to implement the household surveys.
- Polling companies conducted pre-test pilot surveys of the general public in consultation with the Index team, and launched the final survey.
- The team sent the questionnaires to local experts and engaged in continual interaction with them.
- The Index team collected and mapped the data onto the 44 sub-factors with global comparability.
- The Index team constructed the final scores using a five-step process:
- The data were subject to a series of tests to identify possible biases and errors. For example, the Index team cross-checked all sub-factors against more than 60 third-party sources, including quantitative data and qualitative assessments drawn from local and international organizations.
- A sensitivity analysis was conducted by the Econometrics and Applied Statistics Unit of the European Commission’s Joint Research Centre, in collaboration with the Index team, to assess the statistical reliability of the results.
- To illustrate whether the rule of law in a country significantly changed over the course of the past year, a measure of change over time was produced based on the annual difference in the country-level factor scores, the standard errors of these scores (estimated from a set of 100 bootstrap samples), and the results of the corresponding t-tests.
- The data were organized into country reports, tables, and figures to facilitate their presentation and interpretation.
