Underlying cause of death is defined using the International Classification of Diseases, Tenth Revision (ICD-10).
Figures are based on deaths occurring in each period (August through to the following July). Numbers of deaths from January to July 2015 are provisional, and have been adjusted to take account of late registrations (see Background note 3 in the statistical bulletin).
The excess winter mortality (EWM) index is calculated as excess winter deaths divided by the average non-winter deaths, expressed as a percentage.
A more detailed version of Figure 7 showing excess winter mortality, broken down by sex and age group can be found in table 1 in this Excel document.
Figures for England and Wales include deaths of non-residents.
