IN a previous paper (Kermack, McKendrick & McKinlay, 1934 a) a method was developed for the analysis of the death rates of various countries, which exhibited in a concise fashion the main changes which have been occurring during the period for which data are available. The method was shown to be applicable to Scotland and to England and Wales, and it not only demonstrated in a lucid manner the way in which the fall in mortality rates had taken place, but also indicated the further changes which were likely to occur during the next few decades. The population of any one country is composed of sections which differ widely in their social and economic circumstances. It would be of interest to examine the changes which have occurred in the mortality rates of a few limited and approximately homogeneous groups in order to find out what regularities such simple aggregates present and also to compare one group with another. However, the data available in the published reports of Registrars General are not sufficiently detailed to allow of an investigation of this kind being undertaken. Nevertheless, it so happens there is one major division of the population in respect of which the published Scottish figures permit an analysis to be made. This is the division of the whole area into "town" and "country". The contrasting conditions prevalent in these two sections of the community make such an analysis of special significance at the present time. Even although, as will be explained, available data are in some respects imperfect, it was decided to examine them in the light of the principles already found to hold for the whole community. A brief description of this previous work will facilitate the understanding of the rest of this paper. In our previous paper it was shown that the specific mortality rate for any age group at any time could be approximately expressed as the product of two factors, one of which, /J, depended only on the age of the group, the other, a, only on the date of birth. This really means that the same generation—say those born in 1900—throughout its life experiences at every age a series of mortality rates which are in the same relative proportion to each other as
