Based on census tract information, cancer incidence rates for three socio‐economic strata of the city of Cali, Colombia, were calculated. Strong negative associations with socio‐economic status were found for cancers of the cervix and stomach. Colon cancer and endocrine‐related cancers were positively associated with socio‐economic status, while no such association was found for rectal cancer. Contrary to data from developed countries, all smoking‐related cancers were positively associated with socio‐economic class. The role of socio‐economic gradients in developing countries is stressed as a basis for etiological research.
