Earlier analyses of the birth cohorts from 1850 to 1922 from the Historical Sample of the Dutch Population by van Poppel and van Gaalen and Schenk and van Poppel conclude that there is no significant variation of mortality by occupation in those generations. A re-examination of their material with special attention to possible changes over time confirms this conclusion for the birth cohorts from 1850 to 1890. For later cohorts the results are anomalous and perverse, and I can offer no explanation. |
