For historical reasons, the best known life tables and those most often used are period tables. They are built using death rates by age for a short period of observation (often a single year) and have as their purpose to represent the status of mortality for this period. The survivors and deaths appearing in their columns are in a way abstractions rather than reality. It is thus erroneous to believe that the life table for a given year (for example, 1995) serves in any way whatever to predict the rate at which those born that year will pass away and, hence, of the average length of the life that they have just begun. With rare exceptions, the average number of years lived by individuals has always been longer than the life expectancy found in the life table constructed for the year of their birth. This is due to the fact that period tables are established using the risks of death by age prevailing in that year. But the ceaseless battle against death reduces these risks year after year for these ages and, by growing older, people benefit from these successive gains.
To reconstitute (or foresee) the rate at which the members of a cohort have (or will) really pass away, it is necessary to deploy very long series of death rates by age and to possess reliable indicators of missing data, and then to adjust them to establish the actual experience of the persons in a cohort. Built in exactly the same way as period tables, these tables are naturally called cohort tables, but comparing observations of their parameters yields conclusions of a different kind.

- 3. Cancer incidence and mortality, 1997 ArchivedArticles and reports: 82-003-X19960043024Geography: CanadaDescription:
In 1997, there will be an estimated 130,800 new cases of cancer and 60,700 deaths from the disease, an increase of one third and one quarter, respectively, over 1987. These increases are due mainly to the growth and aging of the population. (All figures exclude non-melanoma skin cancer.) In 1997, three types of cancer will account for at least half of all new cases in men and women: prostate, lung and colorectal cancer for men; breast, lung and colorectal cancer for women. Lung cancer will be the leading cause of cancer death in 1997, resulting in one-third of cancer deaths for men and almost one-quarter of cancer deaths for women. Among women, overall trends in age-standardized rates of cancer incidence and mortality have remained relatively stable since 1985, as large increases in the rate of lung cancer have been offset by declining or stable rates for most other forms. Among men, the overall incidence rate is rising slightly as a result of the sharp increase in the incidence of prostate cancer. The mortality rate for men peaked in 1988 and has since declined, because of decreases in the rates for lung, colorectal and some other cancers. This article presents information on trends since the mid-1980s in cancer incidence and mortality, adapted from Canadian Cancer Statistics 1987.
