The aim of this study was to map standardized mortality ratios (SMRs) of specific cancers in Argentina and to examine some ecological relationships using Poisson regression, Poisson regression with frailties, and empirical Bayes estimates. Mortality data for lung cancer, nonmelanoma skin cancer, melanoma, and stomach cancer were obtained from national registers for the period 1989-1993. Overcrowding and unsatisfied basic needs (UBN) were used as indicators of socioeconomic status and people working permanently on farms as an indicator of rural activity. Empirical Bayes estimates provided a good solution for mapping rare causes of cancer when random fluctuations of observed deaths are important, as in the case of nonmelanoma skin cancer (NMSC) and melanoma. In the case of lung and stomach cancers the main improvement was the attenuation of confidence intervals. Lung cancer rates (males and females) were higher in jurisdictions with better socioeconomic status. When the variable UBN was categorized in tertiles (
