[Incorporation of work disability into the prolonged life expectancy process]

The various reasons of deficiency, as e.g., mortality, invalidity and notification of illness result in a decrease of the potential of work of the labour. Because of the mutual influence of these reasons, an isolated assessment of them only can be performed in a restricted manner. The loss of working years in male workers and clerks of the GDR (SV FDGB 1982) is calculated and assessed on the basis of the various reasons of deficiency.
