This note continues a regular series on mortality rates in Great Britain; the previous note in the series appeared in J.I.A.114, 135 and dealt with mortality in 1984 and 1985.

Following the 1981 Census, estimates of the resident population have been produced on a new definition. This includes residents temporarily outside the country but excludes foreign visitors. It includes members of both H.M. and foreign forces stationed in the United Kingdom but excludes members of H.M. forces who are stationed abroad. The figures for deaths are not precisely consistent with the new definition of the population, since they do not necessarily include all deaths of residents temporarily absent from the U.K.

1.1 In March 1987 the Futures Committee of the Institute considered a preliminary report (Daykin, 1987) on the possible impact of AIDS in the United Kingdom and the consequences for life insurance. The Committee recommended the setting up of a Working Party to study the problem. The Working Party on AIDS was accordingly established, under the auspices of the Research Committee. The authors of this paper formed the membership of the Working Party, under the chairmanship of C. D. Daykin.

1. In this note I describe the mathematical formulation of a model for representing the spread of AIDS in a population, which is designed for actuarial use in dealing with life insurance companies and pension funds. A major requirement of actuaries is that the model should be age-specific, and should take into account normal age-specific mortality as well as the extra sickness and mortality from AIDS.
