EWM figures are based on deaths occurring in each period. Numbers of deaths from January to July 2015 are provisional, and have been adjusted to take account of late registrations (see Background notes 2 and 3 in the statistical bulletin).
Figures for the latest winter are provisional and are rounded to the nearest 100, figures for all other winters are final and are rounded to the nearest 10.
The lower and upper confidence limits (LCL and UCL) form a confidence interval, which is a measure of the statistical precision of an estimate. More information on the calculation and interpretation of excess winter deaths, the excess winter mortality index and confidence intervals can be found in the Definitions sheet.
The excess winter mortality (EWM) index is calculated as excess winter deaths divided by the average non-winter deaths, expressed as a percentage.
Figures for England, English regions and Wales exclude deaths of persons usually resident in each area. Figures for England and Wales combined also include deaths of non-residents.
