Life table analysis for areas using vital register data.

"This study considers the utility of parameterised life tables derived by survival analysis for comparing mortality between areas, using death registration records and accompanying information on the social characteristics for each individual deceased. Such methods enable a comparison of summary measures of mortality experience such as life expectancy and median age at death before and after adjustment for socio-economic variables. In the absence of comparable information on the survivor population an approximate life table method is investigated as a means of comparing mortality profiles and the effects of social factors. Such factors may pertain both to the individuals (e.g. their birthplace) or to their small area of residence (e.g. measures of area deprivation). These methods also permit a comparison of the impact of socio-economic factors on different causes of death. The application is to mortality in London over the period 1990-92 and to its constituent boroughs and electoral wards." excerpt
