Notes: Results presented in this table are elasticities, contributions, and percentage contributions of cigarette smoking and alcohol consumption to income-related health inequality. The results are obtained by decomposing the income-related health inequality indices into health related covariates, including smoking and alcohol use. Self-reported health is binary and the health index is continuous with high values representing poor health outcomes. The tobacco and alcohol use variables is categorical. Other covariates include household per capita income, gender, categories for age, province of residence, race, marital status, and education
