Job Exposure Matrices (JEM) for four different types of job demands that can be matched via the occupational classifications ISCO-88 or KldB-92 to any kind of dataset. Every job category coded according to ISCO-88 is represented in the index: 100% of all 2-digit ISCO-88 codes, 94.8% of the 3-digit codes, and 78.5% of the 4-digit codes can be matched. The JEM were originally proposed in the paper: Kroll LE (2011) Construction and Validation of a General Index for Job Demands in Occupations Based on ISCO-88 and KldB-92. MDA – Methoden, Daten, Analysen 5 (1): 63-90.
