Which tasks workers perform in their jobs is critical for how technological change plays out in the labour market. This article critically reviews existing measures of occupational task content and makes the case for rethinking how this concept is operationalised. It identifies serious shortcomings relating to the theoretical content and the empirical implementation of existing measures. Based on survey data from European Union countries between 2000 and 2015, it then introduces novel measures of routine task intensity and task complexity at the International Standard Classification of Occupations 1988 two-digit level that address these shortcomings. The indices will contribute to a more theoretically informed understanding of technological change and benefit both labour economists and sociologists in investigating the nature of recent technological change.
