In societies which do not have universal registration systems for monitoring demographic change it is not normally possible to accurately study the process of linking population and mortality data. The NI-LS is unique within the United Kingdom in that it affords such a possibility. The study links the 2001 Census returns to all deaths registered in Northern Ireland in the five years after the Census, with the characteristics of matched and non-matched death records compared using multivariate logistic regression. The attributes of the subjects included in the analysis are as recorded on the death certificate.
