Economic activity  (ECONOMIC activity)


The study of economic activity1 includes the determination of age at entry2 into employment and of age at withdrawal3 or age at retirement3 (324-7). The period between age at entry and age at retirement is called working life4. Occasionally, the expectation of working life5 of persons of a given sex and age is computed; analogous to the computation of the expectation of life (433-3) this shows the mean length of time for which a cohort (116-2) of persons would continue as members of the labour force.
