Mortality by Age and Sex: The Adult Ages

  • H. O. Lancaster


For convenience of exposition, the experience of the developed world only is being considered in this chapter. In every epoch the death rates from the infections, excluding tuberculosis and syphilis, are much lighter at ages above 25 years than at younger ages. Some of these differences are due to the solid immunity that follows some of the infections, for example, measles; others are due to immunologic changes following experience with a number of infections by which the body is able to cope with other diseases sufficiently closely related. In any case, growth has ceased, and the body is at full strength to withstand the infections and the environment. The result is that there is an almost negligible adult mortality in the developed world from such specific infections as diphtheria, scarlatina, measles and whooping cough, and the infectious respiratory and gastrointestinal diseases that have played such an important part in childhood.
