Using public opinion surveys to evaluate corruption in Europe: trends in the corruption items of 21 international survey projects, 1989-2017

摘要

Many international survey projects contain items on corruption that facilitate comparative analyses of individual-level determinants of perceived and experienced corruption, yet such data remain under-used. To encourage more and better use of the wealth of available survey projects, this article presents a comprehensive review of the largest collection of extant cross-national data suitable for research on corruption in Europe. I examine a total of 1129 items on corruption stemming from 21 international survey projects and their 89 survey waves that cover 45 European countries during the period 1989-2017. Within three decades, the number of corruption items has grown remarkably, rising from just one in 1989 to nearly a hundred in 2017. This article shows the trends: a considerable increase in experiential items; greater differentiation between forms of corruption; a move from items on 'what government has done' to items on 'what ordinary people can do'; and inclusion of items on corruption in private sector. Researchers interested in understanding perceptions and experiences of corruption, as they are shaped by social contexts, are offered an opportunity of exploring the availability of corruption items in international survey projects in a systematic manner in order to analyzed patterns of corruption, its causes and consequences. Concluding part of the paper contains some remarks on the challenges of using survey data on corruption in a comparative framework.
