title: [Mortality differential for cancer based on social class: the metropolitan region of Montreal, 1971].
abstract: Cancer mortality rates vary from area to area. Part of this variation is due to socio-economic characteristics of the area and part to other factors including the availability of health services. Three social indicators associated with cancer mortality are used to estimate variations between low and high census sectors within the metropolitan region of Montreal. The components of socio-economic status which have been used are revenue (median family income), education (college and university level) and occupation (higher status profession). For each of the three zones of the metropolitan area: the city of Montreal, the island of Montreal not included the city of Montreal, the north and south shores of the metropolitan area twenty five census sectors have been chosen which having higher or lower positions for each of the socio-economic components. For each group standardized death rates were evaluated for each type of cancer and the Poisson test was applied to judge whether the differences between the projected rate and the observed rate were significant. The results indicate a strong indirect relation between the standardized mortality rates and the socio-economic status in the central city. In the case of lung cancer, the spatial distribution showed district gradients of occurrence between the central-city and the suburbs.
