title: Implications of changes in the UK social and occupational classifications in 2001 for vital statistics.
abstract: In 2001, three simultaneous changes were introduced which influence the reporting of vital statistics by socio-economic status. Registrar General's Social Class was replaced by the new National Statistics Socio-Economic Status (NS SEC); the Standard Occupational Classification (SOC) was updated from SOC90 to SOC2000; and the coding of employment status on vital statistics changed to stay in line with census coding and SOC2000. This article reports on these changes and describes a method for coding data prior to 2001 to NS SEC (named NS SEC90) in order to facilitate the analysis of health inequalities over time. NS SEC90 allocates 90 per cent of deaths to the same analytical category as NS SEC. This figure varies according to sub group.
