Statistical Quality Assessment
The Center of Excellence in Statistical Information on Government, Crime, Victimization and Justice evaluates the Statistical Quality degree of the crime, security and justice statistical operations.
In a Statistical Quality Assessment, the CoE analyzes the quality of each and every phase of the statistics production process, to verify its methodological rigour and its compliance with the United Nations Fundamental Principles of Official Statistics. This is done with the objective of strengthening the generation of statistics derived from administrative records, surveys or censuses.
