Factsheet 05 has already addressed the topic of demographic change in the world of work. It focuses on the frequency of physical working conditions at workplaces of various levels of requirement depending on age. Furthermore, occupational risks can be explained by work content and work organisation of different occupational groups (Vendramin & Valenduc 2014). The present article uses data from the BIBB/BAuA 2012 Employment Survey to analyse mental demands at work and health aspects for older employees (50-64 years) in several occupational groups and compares these with those of employees in the middle age (30-49 years).
