International comparisons of mortality aimed at revealing age-specific and time-specific differences in survival between Denmark and nine developed countries have been carried out by estimating ratios of death rates in the last decades. To gain deeper insights into this phenomenon, comparative analyses of death rates by causes of death for Denmark, Sweden, the Netherlands, and Japan have been performed. The book is accompanied by a CD-ROM including color Lexis maps, graphs of trends in death rates by causes of death, animated graphs of common survival indicators and a Lexis program for producing Lexis maps.
