Mr. Powellasked the Secretary of State for Wales what are the age-standardised mortality rates from all causes, the infant mortality rate, and the ratio of the local rates to national England and Wales rates, for the years 1945 to 1979 inclusive, for the local authority areas now comprising the county of Mid-Glamorgan.
§ Mr. Wyn RobertsInformation on mortality and infant mortality rates was published annually for old local authority areas in the Registrar General's annual review, part I, (tables, medical) for the years 1945–73. Comparable information for Mid-Glamorgan and districts, for the years 1974–78 is given in "Local Authority Vital Statistics" (Series VS No. 4). Copies of all these publications are in the Library. Data for the periods before and after 1974 are not strictly comparable, due to changes in local authority boundaries. The figures for 1979 for Mid-Glamorgan are as follows:40W
Infant mortality rate per 1,000 live births: 11.8 Deaths per 1,000 population: 12.7 Area comparability factor✶: 1.11 Ratio of local adjusted rate to national England and Wales 1.17 rate: ✶ The product of the area comparability factor and the crude death rate gives an adjusted death rate, which can be compared directly with the experience of England and Wales with differences in age and sex composition accounted for.
