ABSTRACT
At the macro-statistical level, this task of gathering or constructing indicators may tap substantial sources of information. The first three chapters of this section testify to that.
In the first (‘The ageing of the workforce’), population censuses and projections in relation to the workforce have contributed to a description of the changes in the global and sectorial age structures. The second, (‘Elements for a demography of work’) partially uses these same basic data, but also relies on specific surveys about work, with a view in this instance to defining appropriate methods for the analysis of the ‘work courses’ and an understanding of the selection mechanisms. And the third chapter (‘The statistical study of the links between age, work, health and the ESTEV survey example’) illustrates both the purpose and the difficulties involved in a research project based on occupational epidemiology, with data collected simultaneously concerning past and present work, on the one hand, and the state of health, on the other.
