Given the academic and media salience of democracy and its measurement, in this contribution we take a closer look at the various existing datasets. For this purpose, in the first two sections we look at democratic conceptualization and measurement, and then focus on the most used datasets on democracy and assess them against the conceptual criteria illustrated in the first section. The third section focuses on the notion of quality of democracy and how it has advanced the understanding of contemporary democracies. The subsequent section illustrates changes in democratic scoring in European countries over the past 15 years. Our results show that democracy has not become more robust in European countries: on the contrary, several countries witnessed significant democratic deterioration. Furthermore, we show that – with the exception of Polity – the indexes analysed are highly correlated and therefore could be equally useful for an ongoing analysis of European democracies.
