Abstract

The accuracy of pre-electoral polls has been the subject of studies in several countries, however in Portugal the issue is rarely studied, and even the few works on this matter are case studies without a general framework.
This study has a vast analysis, studying almost all the pre-electoral polls published or issued in Portugal since 1991 regarding their accuracy, methodological issues and electoral results. The first part of this text contains a contextualization of polls reality in Portugal, it includes, also, some examples of several studies on measuring polls accuracy. The second part is dedicated to the presentation of accuracy results, their evolution, a comparison with other countries and some methodological characteristics of polls.
