Description: Data contains the mean annual temperature (in degrees F)
and Mortality Index for neoplasms of the female breast.
Data were taken from certain regions of Great Britain, Norway, and Sweden.
Number of cases: 16
Mortality: Mortality index for neoplasms of the female breast
Temperature: Mean annual temperature (in degrees F)
In the early 1960s, data were collected from official statistics registers of Great Britain, Norway and Sweden on breast cancer mortality. Death rates for neoplasms of the breast were calculated for various age groups and for certain areas at the same latitude. Age-specific death rates were
then calculated for each area and converted to a mortality index using 100 as the age-specific rate for all of England and Wales. The mean annual temperatures at various latitudes under study were obtained from the British Meteorological Office.
