Life expectancy and socio-economic status

A useful Irish Times article documents CSO data on how life expectancy varies with socio-economic status and other variables: "Life expectancy is longest among those with the highest social class and the highest level of education. Male professional workers have a life expectancy of 81.4 years, for example, 6.1 years higher than their unskilled counterparts...For women, professional workers have the highest life expectancy, at 86 years, while unskilled workers have the lowest, 81 years."
