Popis:	This paper presents a relational model of age-specific death rates at ages 45–99. It is based upon death rates calculated for single years of age and five-year periods from 1950 to 1985 in 16 low-mortality countries. Eighty-two data sets are used in the construction of the model. These data passed a rigorous quality test which involved comparisons of intercensal changes in cohort size with intercensal deaths. Construction of the model is based upon a logit transformation of death rates, which performed slightly better than a logarithmic transformation in statistical tests. A ‘standard’ mortality pattern is produced as a summary of age-specific death rates in these 82 data sets. Expressed in logits, the standard is highly linear in age for males. For females, systematic curvature of the type first identified by Horiuchi and Coale is observed. The proportionate rate of change in women's age-specific death rates is highest in the age group 70–80. Once this pattern has been embodied in the standard, we are ge...
