Manual on the Measurement of Corruption through Sample Surveys
Taking into account advantages and disadvantages of the most common approaches and corruption measuring tools, UNODC advises to pursue the development of sample surveys for this purpose. Sample surveys have been reckoned as the most effective mechanism to obtain more precise information, to collect better details on different corruption modalities and to know about the actors involved in corrupt offences, all of which provide clear indication to policymakers and anti-corruption agencies.
The methodology for conducting this kind of surveys has been constantly refined in recent years; however, international standards have yet to be produced to allow for international comparability and to produce regional trends and patterns. Therefore, the UNODC-INEGI Center of Excellence took on the task of generating guidelines which can assist and support countries for the development of sample surveys on corruption through a comprehensive manual that draws on existing national and international best practices. In particular, this Manual benefits from the information provided by the Task Force on Corruption Measurement and was presented at the United Nations Data Forum held in October 2018 in Dubai, in the United Arab Emirates.
