- Aims: Life expectancy in Sweden is among the highest in the world, and the province of Halland has the highest life expectancy in Sweden today. In an earlier paper the authors reported that life expectancy in the province of Halland in the south-west of the country was approx. 3.5 years above the national average between 1911 and 1950. The aim of this study was to explore the influence of different causes of death on life expectancy in Sweden and the distribution of these causes of death in Halland compared with Sweden as a whole during the same period of time. Method: Causes of death between 1911 and 1950 in the whole of Sweden and in Halland were obtained from the archives of Statistics Sweden. A trend analysis was performed on the impact of the various causes of death on life expectancy in Sweden. Calendar year, age, and sex were controlled for in a Poisson model. The distribution and incidence of the most frequent causes of death were compared between Halland and Sweden as a whole. Results: The decreasing mortality risk due to infectious diseases and the simultaneous increase in the risk of mortality from tumours and circulatory diseases contributed most to the change in life expectancy in Sweden. In Halland there was a lower mortality risk in the seven most important causes of death, which accounted for approx 80% of all deaths during the study period. Conclusions: The lower mortality risk from infectious diseases mostly favoured the improvement in life expectancy in Halland up to the mid-1930s. Thereafter, a low mortality risk from tumours and particularly circulatory diseases gained increasing importance although there was always a difference in favour of Halland from the beginning of the study period. Thus, the positive trend in life expectancy that favours Halland today seems to have existed for a long period of time.

- Background: Life expectancy in Sweden is currently one of the longest in the world. The population of Halland has the longest life expectancy in Sweden. Aim: Life expectancy in the province of Halland and Sweden as a whole during 1911-50 was studied and the findings are discussed in the light of local historical data. Method: A trend analysis of risk ratio of death and life expectancy for Halland and Sweden was done for the period 1911-50 with regard to calendar year, age, and sex using a Poisson model. Results: The risk ratio between Halland and Sweden was 0.83 for 1911 and 0.76 for 1950. The risk ratio of death for women was lower compared with men and this difference increased over time. At the start of the study period life expectancy for men and women was higher in Halland (58.5 and 60.1 years, respectively) compared with Sweden (54.7 and 56.4 years, respectively) with a difference of approximately 3.8 years. At the end of the study period this difference in life expectancy for men and women in Halland (71.3 and 72.3 years, respectively) and the nation ( 68.0 and 69.2 years, respectively) had decreased to approximately 3.3 years. Conclusion: The long life expectancy seen in Halland today can be traced back to the early twentieth century. The starting point for this development seems to be a lower infant mortality in Halland compared with Sweden as a nation during the 1880-90. The basis for this might have been a greater increase of food production during the whole nineteenth century as well as other socioeconomic characteristics of Halland compared with the rest of the country.
