Manual on corruption surveys

The main purpose of the Manual on Corruption Surveys is to provide countries with methodological and operational guidelines for developing and implementing sample surveys, both among the population and among businesses, in order to measure the prevalence of bribery at national level and to collect other relevant information on corruption. A particular goal of this Manual is to support countries’ measurement of their progress towards achieving Sustainable Development Goal 16 target 5: “Substantially reduce corruption and bribery in all their forms“. In highlighting the value of producing experience-based statistical information on corruption, the advantages and disadvantages of different approaches to measuring bribery and other forms of corruption are also illustrated.

Intended as a tool for those wishing to understand and analyse corruption in a scientific manner, the Manual on Corruption Surveys is primarily targeted at national statistical agencies, anti-corruption bodies, relevant national institutions, research centres, non-governmental organizations and private sector entities. The Manual does not cover general methodological issues related to sample surveys, for which various technical instruments and standards have been produced by the international community for decades. Instead, the information contained within is aimed at guiding national authorities interested in conducting sample surveys on corruption, from the planning stage to the analysis and dissemination of results.
