BACKGROUND Northern regions of Iran have been encountered to dominate malignancies of gastrointestinal (GI) tract. We aimed to examine the excess mortality due to the GI tract cancer in Mazandaran province. METHODS Socio-demographic and clinical data of 484 patients with GI cancer collected during the years 1990-1991 were available from Babol Cancer Registry Center in Iran. Patients were foll...

Despite its widespread use, the Coale–Demeny model life table system does not capture the extensive variation in age-specific mortality patterns observed in contemporary populations, particularly those of the countries of Eastern Europe and populations affected by HIV/AIDS. Although relational mortality models, such as the Brass logit system, can identify these variations, these models show sys...

demography is a realm of private decisions with public effects. in both highand low-fertility regimes, families make decisions that significantly influence the well-being of others. excessively rapid population growth can threaten economic and ecological viability. Population decline can threaten cultural continuity and fiscal sustainability. as Paul demeny has warned us, there is no invisible ...

in his brilliant editorship of Population and Development Review, Paul demeny encouraged both types of research on demographic change. this essay is in the spirit of the first type of study. rather than dealing with the entire population, however, it restricts its attention to ages above 65, where population changes reflect, amplify, and reshape the broad patterns associated with the demographi...

Mortality estimates for many populations are derived using model life tables, which describe typical age patterns of human mortality. We propose a new system of model life tables as a means of improving the quality and transparency of such estimates. A flexible two-dimensional model was fitted to a collection of life tables from the Human Mortality Database. The model can be used to estimate fu...

BACKGROUND The under-five mortality rate (the probability of dying between birth and age 5 y, also denoted in the literature as U5MR and (5)q(0)) is a key indicator of child health, but it conceals important information about how this mortality is distributed by age. One important distinction is what amount of the under-five mortality occurs below age 1 y ((1)q(0)) versus at age 1 y and above (...
