    “If the populations of all areas were similarly constitu- ted (it is pointed out) as regards the proportions of their sex and age group components, their crude death rates (deaths per 1,000 of population) could be accepted as valid comparative meas- ures of the mortalities experienced by the several populations.” In order to correct any differences “the average mortality rates experienced in England and Wales during the three years 1930-32 divided into 11 sex-age Groups have been adopted as the standard and have been applied to the corresponding sex-age groups in the 1931 census population of every Borough, Urban District and Rural District in the Country. The adjusting factor now supplied in respect of a given area represents the ratio of the resulting death rate for the national 1931 census population to the similarly obtained hypothetical death rate for the said area.” The standardising factors provided by the Registrar General and used in previous reports corrected differences for age and sex, but in comparison with the standardised national rate based upon the 1901 population for England and Wales, and not in comparison with the contemporaneous crude death rate for England and Wales. For the former comparison the comparability factor must be reduced by multiplying it by '820. The following were the principal causes of death for the year 1934. Reference to particular diseases is given later in the Report.
