Measuring Trends in Male Mortality by Socio-Economic Group in Ireland: A Note on the Quality of Data

The objective of this paper is to examine measurement issues and data problems in the analysis of trends in male mortality differentials by socio-economic group in Ireland between 1981 and 1991. The study is based on mortality data supplied by the Central Statistics Office and population data taken from the 1981 and 1991 Census. Measurement problems in the area of death registration worsened between 1981 and 1991, making it impossible to discuss trends in mortality in Ireland with any confidence. Significantly, more deceased people ended up in the residual category in 1991 than in 1981. This is related to an increasing problem of apportioning 'gainfully employed' decedents to a socio-economic group rather than any problem with people described as 'not gainfully employed'.
