Education specific age standardised mortality rates,* relative risks,† relative indices of inequalities (RII),‡ and rate differences§ among Korean men and women aged 30–59: Korean 1990, 1995, 2000 census and 1990–1991, 1995–1996, 2000–2001 death certificate data

*Age standardised mortality rates were calculated with age adjustment to one year age groups according to the direct method with the distribution of 2000 census data as the standard; †relative risks were computed using Poisson regression analyses with the data of sex, cause, one year age, education specific number of death and population. “college or higher” groups was the referent (1.0); ‡relative indices of inequalities were computed using Poisson regression analyses with the data of sex, one year age, cause, education specific number of death and population; §rate difference = (age standardised mortality rates in college or higher group)–(ages standardised mortality rates in elementary or less group).
