Notes: Results presented in this table are corrected concentration indices for smoking-related health inequality. The health indicators are all binary outcomes equivalent to 1 if the respondent is diagnosed of a given disease. The health index is continuous with high values representing poor health outcomes. The cigarette smoking variables are both continuous. Positive values of smoking-related health inequality indices indicate that poor health is concentrated among heavy smokers and those with longer smoking duration. ***Statistically significant at the 1% level; statistically significant at the 5% level; *statistically significant at the 10% level
