We study how the de-routinisation of jobs affects workers at different ages in 12 European countries. We combine O*NET occupation content data with EU-LFS individual data for the 1998–2015 period to construct five task content measures: non-routine cognitive analytical, non-routine cognitive interpersonal, routine cognitive, routine manual, and non-routine manual physical. We find that the shift away from routine work and toward non-routine work occurred much faster among workers aged between 25 and 44 than among older workers. In the majority of countries, the ageing of the workforce occurred more quickly in occupations that were initially more routine-intensive, as the share of older workers in these occupations was rising and the share of young workers declining. At the same time, the unemployment risk related to the routine task intensity was increasing, especially among individuals between the ages of 15 and 34, and to a larger extent in countries with fast ICT capital growth and in countries not increasing their participation in global value chains.
