Winter Mortality in Northern Ireland 2022/23

Date published: 07 December 2023

The Winter Mortality report (formerly known as Excess Winter Mortality) for 2022/23 was released this morning. It contains analysis on the difference between the actual number of winter deaths in December 2022 to March 2023 and the expected number of deaths.

The report on Winter Mortality (WM) includes information on the provisional number of deaths that took place in Northern Ireland in the winter months of December 2022 to March 2023, compared with the non-winter months (including the preceding August to November 2022 and the following April to July 2023).

There were 6,199 deaths in Northern Ireland in the four months of winter 2022/23 (December to March). Comparing this with the average for the two adjacent 4-month periods, the seasonal increase in mortality in winter 2022/23 was an estimated 940.

The report and accompanying table can be accessed on the winter mortality page.
