We are very happy to announce the release of an updated cumulated trend dataset built from the ISSP Social Inequality I-V modules. It now includes data from 1987, 1992, 1999, 2009, and the most recent wave of ISSP 2019. It covers 35 countries from across the world and allows combined cross-national and trend analyses over three decades.
