Abstract: | An analysis of differential mortality by region in Poland for the periods 1976-1978 and 1984-1986 is presented. The results show not only that significant differences existed in the earlier period, but that they increased in the second period, particularly with regard to differences between the east and west of the country. Poland seems therefore an exception to the trend in many developed countries toward a decline in geographic mortality differentials associated with the post-demographic transition era. |
