• For more information on different measures of excess death and our current work around excess mortality, please read our blog post, How do we measure expected and excess deaths?.

In the week ending 21 April 2023 (Week 16), 12,420 deaths were registered in England and Wales. Of these, 11,574 were registered in England and 821 were registered in Wales (Table 1).

The number of deaths from all causes was above five-year average in England and Wales in the week ending 21 April 2023 (Week 16). Figure 1 shows the number of deaths involving coronavirus (COVID-19) and not involving COVID-19.

Number of deaths registered by week, England and Wales, 28 December 2019 to 21 April 2023

Notes:

1. Figures include deaths of non-residents.
2. Based on date a death was registered rather than occurred. 
3. All figures are provisional. 
4. The International Classification of Diseases, 10th Edition (ICD-10) definitions are available in Section 5: Measuring the data. 
5. The number of deaths registered in a week is affected when bank holidays occur. 
6. The five-year average for each year is as follows: 2017 to 2019, and 2021 to 2022 for comparisons with 2023; 2016 to 2019 and 2021 for comparisons with 2022; and 2015 to 2019 for comparisons with 2020 and 2021.

Coronavirus (COVID-19) deaths

COVID-19 deaths are those deaths registered in England and Wales in the stated week where COVID-19 was mentioned on the death certificate. A doctor can certify the involvement of COVID-19 based on symptoms and clinical findings; a positive test result is not required. Definitions of COVID-19 for deaths in Scotland and Northern Ireland are similar to England and Wales.

Excess deaths

The term excess deaths in this statistical bulletin refers to the number of deaths above the five-year average. For 2020 and 2021, the average for 2015 to 2019 has been used. For 2022, the average is calculated from 2016 to 2019 and 2021 data. For 2023, the average is calculated from 2017 to 2019, 2021, and 2022 data. This provides a comparison of the number of deaths expected in a usual (non-coronavirus pandemic) year.

We publish timely, provisional counts of death registrations in our Deaths registered weekly in England and Wales, provisional dataset. These are presented:

• by sex
• by age group
• for regions (within England)
• for Wales as a whole

To allow time for registration and processing, figures are published 11 days after the week ends. We also provide provisional updated totals for death occurrences based on the latest available death registrations, up to 29 April 2023.

The five-year average shows us the expected number of deaths per week based on the most recent years and smooths random year-on-year fluctuations. We use the 2015 to 2019 five-year average as a usual non-coronavirus (COVID-19) period to compare with. The further we move away from this period, the less robust the measure is because of changes in population numbers, age, and structure.

Deaths registered in 2023 will be compared with the 2017, 2018, 2019, 2021 and 2022 five-year average.

The number of registration days in a reference period can affect mortality statistics. Bank holidays can affect the number of registrations because registration offices are closed.

Coronavirus

This weekly release provides a breakdown of the number of deaths involving coronavirus. This includes deaths where COVID-19 or suspected COVID-19 was mentioned anywhere on the death certificate, including in combination with other health conditions.

If a death certificate mentions COVID-19, it will not always be the main cause of death but may be a contributory factor.

Data coverage

The number of weeks in the year will affect how many days the data cover in the year. Leap years require a 53rd week to be added to the end of the calendar year. The last leap year was in 2020. It is more appropriate to compare 2020 figures with the average for Week 52 than with a single year from five years previously. Read more on the data coverage for the weekly deaths bulletin in Section 1 of our Coronavirus and mortality in England and Wales methodology.

Influenza and pneumonia have been included for comparison in our Deaths registered weekly in England and Wales, provisional dataset. These illnesses are a well-understood cause of death involving respiratory infection likely to have somewhat similar risk factors to COVID-19.

Registration delays

This bulletin is based mainly on the date that deaths are registered, not the date of death. Deaths in England and Wales are normally registered within five days. There can be a longer delay, particularly if the death is referred to a coroner. Read more in our Impact of registration delays on mortality statistics in England and Wales article.

We have developed a statistical model to estimate the number of deaths likely to have occurred in each week based on the previous pattern of registration delays, including the effects of bank holidays. Read more in our Predicting total weekly death occurrences in England and Wales methodology. Results are shown in sheet 11 of our Deaths registered weekly in England and Wales, provisional dataset.

Classification codes

From the week ending 26 February 2021 (Week 8), new International Classification of Diseases codes for COVID-19 issued by the World Health Organization (WHO) were used for deaths involving COVID-19. Read more in our Coronavirus and mortality in England and Wales methodology.

Comparability

These weekly figures are for England and Wales only. They are from the formal death registration process and may include cases where the doctor completing the death certificate diagnosed possible cases of coronavirus (COVID-19), for example, based on relevant symptoms, but where no test was conducted. The Office for National Statistics (ONS) figures are different from the daily surveillance figures on COVID-19 deaths published by the Department of Health and Social Care (DHSC) on GOV.UK, which are for the UK as a whole and its constituent countries.

On 1 February 2022, the UK Health Security Agency technical summary data series was revised to include deaths of positively tested individuals where the death occurred within 28 days, and deaths within 60 days of a positive test. Read more in the UK Health Security Agency technical summary (PDF, 443KB).

Some definitions of COVID-19 deaths differ between sources and settings. Read more in our Coronavirus and mortality in England and Wales methodology.
