Notes: All models control for year of birth, migration status (not included for the first two periods), civil status, and parish of residence. The number of deaths and person-years at risk are given in Table 1. All models are statistically significant below the 5 % level based on a chi-square test. For models in panel B, social class is measured by the highest social class in the family for married people.
