Research agrees that the importance voters ascribe to political issues, ie individual-level issue salience, affects political behaviour. However, due to measurement limitations, we lack research on who considers which issues important. Specifically, the often-used most-important-problem/issue question complicates between-individual comparisons of issue salience. Using a rarely employed measurement of issue salience and data from six Western European countries, this research note explores the salience of different issues across different socio-demographic groups. Our exploratory findings suggest that different socio-demographic variables affect different issues’ salience across and within individuals over time. Further, we find that predictors of individual-level issue salience and attitudes frequently differ – highlighting the importance of analysing them separately. We call for research on individual-level issue salience using measurements that enable the study of its determinants and analysing predictors of salience and attitudes separately.
