Deaths registered weekly in England and Wales, provisional: week ending 2 April 2021

• The number of deaths registered in England and Wales was affected by the Good Friday Bank Holiday; 8,201 deaths were registered in England and Wales in the week ending 2 April 2021 (Week 13), 1,844 fewer deaths than the previous week (Week 12).

• In Week 13, the number of deaths registered in England and Wales was 19.0% below the five-year average (1,929 fewer deaths); this is the fourth consecutive week that deaths have been below the five-year average; because of the movement of Easter, Good Friday does not always fall in Week 13 so may not be included in the average

• We estimate that the number of deaths actually occurring (rather than registered) in Week 13 in England and Wales was between 8,669 and 11,301.

• Of the deaths registered in Week 13 in England and Wales, 400 mentioned “novel coronavirus (COVID-19)”, a decrease of 319 deaths compared with Week 12.

• In Week 13, deaths involving COVID-19 accounted for 4.9% of all deaths in England and Wales, compared with 7.2% in Week 12.

• Of the 400 deaths involving COVID-19 in Week 13 in England and Wales, 308 had this recorded as the underlying cause of death (77.0%).

• Of the 1,121 deaths that involved Influenza and Pneumonia, 237 had this recorded as the underlying cause of death (21.1%).

• In England, the total number of registered deaths decreased from 9,381 (Week 12) to 7,706 (Week 13); the number of deaths registered involving COVID-19 decreased in all English regions compared with Week 12, with the largest decrease recorded in the East Midlands (53 fewer deaths).

• In Wales, the total number of deaths registered decreased from 651 (Week 12) to 483 (Week 13); in Wales, the number of deaths registered involving COVID-19 decreased from 32 (Week 12) to 15 (Week 13).

• The number of deaths registered in the UK in the week ending 2 April 2021 was 9,458, which was 2,088 fewer than the five-year average; of deaths registered in the UK in Week 13, 450 involved COVID-19 (350 lower than in Week 12).

The number of deaths registered in 2020 Weeks 19, 20, 22, 23, 36, 37, 52 and 53 and in Weeks 1 and 13 2021 were affected by early May, late May, August, Christmas, New Year and Good Friday Bank Holidays (Friday 8 May 2020, Monday 25 May 2020, Monday 31 August 2020, Friday 25 December 2020, Monday 28 December 2020, Friday 1 January 2021, Friday 2 April 2021); the impact of the early May Bank Holiday was analysed in our Week 20 bulletin.
5. The Week 52 five-year average is used to compare against Week 53 deaths.
6. The five-year average has been provided for 2015 to 2019 (rather than 2016 to 2020) because of the impact of the coronavirus (COVID-19) pandemic on deaths registered in 2020. The average for 2015 to 2019 provides a comparison of the number of deaths expected per week in a usual (non-pandemic) year.
7. The Good Friday Bank Holiday appears in different weeks across different years. For 2015 it was in Week 14, for 2016 and 2017 it was in Week 15, in 2018 it was in Week 13 and in 2019 it was in Week 16.

The provisional number of deaths registered in England and Wales decreased from 10,045 in Week 12 (week ending 26 March 2021) to 8,201 in Week 13 (week ending 2 April 2021). Week 13, however, included the Good Friday Bank Holiday when register offices are likely to be closed, which may account for some of the decrease in comparison with Week 12. Therefore, trends should be interpreted with caution in this week’s and the next few weeks’ publications.

The number of deaths was 19.0% below the five-year average (1,929 fewer deaths). The Good Friday and Easter Monday Bank Holidays appear in different weeks depending on the year. For 2015, the Good Friday Bank Holiday appeared in Week 14, for 2016 and 2017 it was in Week 15, in 2018 it was in Week 13 and in 2019 it was in Week 16. The Easter Monday Bank Holiday then appears in the following week. Comparisons with the five-year average should be treated with caution for Weeks 13 to 17.

In England, the number of deaths decreased from 9,381 in Week 12 to 7,706 in Week 13, which was 1,708 deaths (18.1%) fewer than the Week 13 five-year average (Figure 1). This is the fourth consecutive week that deaths have been lower than the five-year average in England.

In Wales, the number of deaths decreased from 651 in Week 12 to 483 in Week 13. The total number of deaths remained below the five-year average for Wales for the fifth consecutive week (182 fewer deaths; 27.4% below the five-year average).

The number of death registrations in England and Wales involving the coronavirus (COVID-19) decreased from 719 in Week 12 to 400 in Week 13, a 44.4% decrease. Of all deaths registered in Week 13, 4.9% mentioned COVID-19 on the death certificate.

In England, the number of deaths involving COVID-19 in Week 13 was 385, accounting for 5.0% of all deaths compared with 7.3% in Week 12.

In Wales, there were 15 deaths involving COVID-19, accounting for 3.1% of all deaths compared with 4.9% in Week 12.

Of the 400 deaths in England and Wales that involved COVID-19, 308 had this recorded as the underlying cause of death (77.0%, Figure 2). Of the 1,121 deaths that involved Influenza and Pneumonia, 237 had this recorded as the underlying cause of death (21.1%).

Deaths that involved both COVID-19 and Influenza and Pneumonia have been included in both categories for consistency when comparing with the underlying cause of death. Influenza and Pneumonia has been included for comparison as a well-understood cause of death involving respiratory infection that is likely to have somewhat similar risk factors to COVID-19. More detailed analysis is available in our Deaths due to coronavirus (COVID-19) compared with deaths from influenza and pneumonia release.

We have developed an experimental statistical model to estimate the number of deaths that actually occurred in a given week, rather than the number registered. For Week 13, we estimate that 9,857 deaths occurred in England and Wales, with a 95% confidence interval of 8,669 to 11,301. This is 567 fewer deaths than the mean for the period 2015 to 2019 in Week 13, and an increase of 326 from the Week 12 2021 estimate of 9,531 (9,224 to 9,909).

These are provisional estimates that assume the pattern of occurrences can be predicted based on experience in previous years. The estimate for the most recent week always has a wider margin of error than for earlier weeks, so it should be treated with caution.

Analysis in this section includes deaths from Week 11 of 2020 (week ending 13 March 2020, the week of the first registration of a death involving COVID-19) through to Week 13 of 2021 (week ending 2 April 2021), to ensure full coverage of the ongoing coronavirus (COVID-19) pandemic.

Using the most up-to-date data we have available, the number of deaths from the week ending 13 March 2020 up to 2 April 2021 was 679,851 in England and Wales. Of the deaths registered by 2 April 2021, 138,057 (20.3%) mentioned COVID-19 on the death certificate. During this period, the number of excess deaths above the five-year average was 116,814 deaths.

In England, the number of deaths between the week ending 13 March 2020 and 2 April 2021 was 637,816, and of these, 130,065 deaths (20.4%) mentioned COVID-19. This was 111,805 deaths above the five-year average.

In Wales, the number of deaths was 41,208 and of these, 7,812 deaths (19.0%) mentioned COVID-19. This was 5,808 deaths above the five-year average.

In Week 13 (week ending 2 April 2021), the number of deaths involving the coronavirus (COVID-19) in England and Wales decreased in most age groups compared with Week 12. The biggest decrease was seen in those aged over 90 years (66 fewer deaths). The majority (60.5%) of deaths involving COVID-19 were in people aged 75 years and over, however the proportion has been decreasing.

Since the beginning of the coronavirus pandemic (up to week ending 2 April 2021), 54.3% of all deaths involving COVID-19 have been in males (Figure 4). There have been more deaths in females aged 85 years and over (31,415) than males aged 85 years and over (26,177). However, these numbers do not account for the population structure where there are more women aged 85 years and over than men.

In Week 13 (week ending 2 April 2021), the total number of deaths registered was lower than the five-year average in Wales and in every English region (Figure 5). The largest decreases on the five-year average were in the East of England (23.5% lower) and the East Midlands (24.1% lower). Caution should be used when comparing Week 13 to the five-year average because of the moving Good Friday Bank Holiday.

Across the English regions, the South East had the largest number of deaths involving the coronavirus (COVID-19), with 65 deaths. The English region with the highest proportion of deaths involving COVID-19 was the East Midlands, where 7.2% of deaths from all causes involved COVID-19.

Deaths involving COVID-19 decreased in all regions, with the East Midlands reporting the largest decrease (53 fewer deaths). This is the ninth consecutive week in which all English regions recorded a decrease. More detailed geographic analysis can be found in our Monthly mortality analysis release.

In Week 13, there were 15 deaths involving COVID-19 registered in Wales – a 53.1% decrease compared with Week 12 (32 deaths).

The Good Friday Bank Holiday may account for some of the decrease in comparison with Week 12.

Of deaths involving the coronavirus (COVID-19) in 2020 and up to Week 13 (week ending 2 April 2021), 69.1% (95,421 deaths) occurred in hospitals, with the remainder occurring in care homes (31,895 deaths), private homes (7,697), hospices (2,048), other communal establishments (498), and elsewhere (498).

Between Weeks 12 and 13, the number of deaths involving COVID-19 decreased in hospitals (231 fewer), private homes (24 fewer), care homes (52 fewer), hospices (7 fewer), other communal establishments (1 fewer) and elsewhere (4 fewer).

Deaths involving COVID-19 in hospitals as a proportion of all deaths in hospitals fell to 7.8% in Week 13 (11.6% in Week 12). Deaths involving COVID-19 in care homes accounted for 4.9% of deaths, a decrease from Week 12 (6.8%).

Detailed analysis on deaths of care home residents is available in Deaths involving COVID-19 in the care sector, England and Wales: deaths occurring up to 12 June 2020 and registered up to 20 June 2020.

From Week 1 2021 (week ending 8 January 2021) onwards, we have published a dataset of weekly deaths of care home residents. The term “care home resident” used in this dataset refers to all deaths where either the death occurred in a care home, or the death occurred elsewhere but the place of residence of the deceased was recorded as a care home. The figures should not be confused with “deaths in care homes” as reported within this bulletin, which refers only to the first category.

As well as the Office for National Statistics (ONS) data, the Care Quality Commission (CQC) provides numbers of deaths involving COVID-19 in care homes in England that are based on the date the death was notified to the CQC. From 10 April 2020 (the first day when data were collected using the CQC's new method of identifying deaths involving COVID-19) to 9 April 2021, there were 28,997 deaths of residents in care homes involving COVID-19. Of these deaths, 41 were notified between 3 April 2021 and 9 April 2021. More information on the data provided by the CQC can be found in our joint transparency statement.

In Wales, the Welsh Government publishes the number of deaths of care home residents involving COVID-19 notified to the Care Inspectorate Wales (CIW). Between 1 March 2020 and 2 April 2021, there were 1,920 deaths of residents in care homes involving COVID-19.

More information on how these numbers have compared throughout the pandemic can be found in our previous Comparison of weekly death occurrences in England and Wales release.

In Week 13, the number of deaths in private homes was 10.8% above the five-year average (255 excess deaths). Deaths in care homes, hospitals and other settings were below the five-year average. Deaths within care homes were 30.7% below the five-year average (683 fewer deaths), deaths in hospital were 30.2% below the five-year average (1,438 fewer deaths) and deaths in other settings were 8.3% below the five-year average (65 fewer deaths).

Looking in more detail at deaths in private homes in Week 13, females accounted for 132 excess deaths compared with 124 for males.

The Deaths in private homes release provides analysis for deaths registered from 28 December 2019 to 12 September 2020. In addition, more detailed analysis of excess deaths in England is produced by Public Health England (PHE) on a weekly basis.

Caution should be used when comparing Week 13 to the five-year average because of the moving Good Friday Bank Holiday. The Good Friday Bank Holiday may account for some of the decrease in comparison with Week 12.

Figure 7 is based on date of death for deaths registered up to 10 April 2021, rather than date of registration. As more deaths are registered, deaths per day are likely to increase, especially for later dates. Looking at the number of deaths that occurred in Week 13, 72.9% of deaths occurred in hospitals, and care homes accounted for 17.1% of all deaths involving COVID-19; this may change as more deaths are registered.

The earliest known death involving COVID-19 occurred in the week ending 31 January 2020 (Week 5).

Across the UK, there were 9,458 deaths (all causes) registered in Week 13 (week ending 2 April 2021), which was 2,088 fewer deaths than the UK five-year average, and 1,991 fewer deaths than in Week 12 (week ending 26 March 2021).

Deaths in all four countries of the UK were below the five-year average in Week 13 for the fourth consecutive week.

Of these deaths, 450 involved the coronavirus (COVID-19), 350 fewer deaths than in Week 12 (43.8% decrease) (Figure 8).

In Week 13, England had the highest number of deaths involving COVID-19 with 385 deaths, followed by Scotland with 38 deaths, Wales with 15 deaths and Northern Ireland with 12 deaths.

Caution should be used when comparing Week 13 to the five-year average because of the moving Good Friday Bank Holiday. The Good Friday Bank Holiday may account for some of the decrease in comparison with Week 12.

We previously published this section as a separate article, which provided a more thorough description of the differences between different data sources. This section will look at the number of deaths by date of death produced by the Office for National Statistics (ONS) compared with death notifications reported on the GOV.UK dashboard. For Wales, we can also compare the data by date of death released by Public Health Wales (PHW).

On 12 August 2020, Public Health England (PHE) revised their data series to include two measures: deaths of positively tested individuals where the death occurred within 28 days and deaths within 60 days of a positive test. More information on these changes can be found in their technical summary.

In England, including deaths that occurred up to 2 April 2021 but were registered up to 10 April 2021, of those we have processed so far, the number involving the coronavirus (COVID-19) was 130,403.

The comparative number reported on GOV.UK (based on data from PHE) where the deaths occurred within 28 days of testing was 111,585 for deaths based on date of notification, and the number of deaths by date of death showed 111,672.

In Wales, including deaths that occurred up to 2 April 2021 but were registered up to 10 April 2021, of those we have processed so far, the number involving COVID-19 was 7,819.

The comparative number of deaths reported on GOV.UK (based on data from PHW) where the death occurred within 28 days of testing was 5,511 for deaths based on date of notification, and the number of deaths by date of death was 5,525.

Coronavirus (COVID-19) deaths

Coronavirus (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.

More quality and methodology information on strengths, limitations, appropriate uses, and how the data were created is available in the Mortality statistics in England and Wales QMI.

To meet user needs, we publish very timely but provisional counts of death registrations in England and Wales in our Deaths registered weekly in England and Wales, provisional dataset. These are presented by sex, age group and regions (within England) as well as for Wales as a whole. To allow time for registration and processing, these figures are published 11 days after the week ends. Because of the rapidly changing situation, in this bulletin we have also given provisional updated totals for death occurrences based on the latest available death registrations, up to 20 March 2021.

Because of the coronavirus (COVID-19) pandemic, our regular weekly deaths release now provides a separate breakdown of the number of deaths involving COVID-19, that is, 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. This bulletin summarises the latest weekly information and will be updated each week during the pandemic.

The data for 2020 are based on a 53-week year. Because the number of days in a week is seven, when there are 52 weeks, we only cover 364 days of the 365 days in the year, which results in one remaining day each calendar year not included in the 52 weeks. With the occurrence of leap years, it is sometimes necessary to add a 53rd week to the end of the calendar, which was the case in 2020. This happens every five years, with the last time there was a Week 53 being in 2015. Given the low frequency of Week 53, it is more appropriate to compare the 2020 figures with the average for Week 52, than to compare it with a single year from five years previous. Therefore, the five-year average used in this bulletin for 2020 is the same as the five-year average used for Week 52.

From the bulletin dated 3 November 2020, we have added two additional analyses.

Previously, we gave a breakdown of deaths involving COVID-19 into those where COVID-19 was the underlying cause of death (“due to COVID-19”) and those where it was a contributory factor (“involving COVID-19”) in the monthly mortality analysis; because of high public interest, this distinction is now shown in Figure 2 of the weekly bulletin.

This bulletin is based mainly on the date deaths are registered, not the date of death, because of the time taken for a death to be registered. Deaths in England and Wales are normally registered within five days, but there can be a considerably longer delay in some circumstances, particularly when the death is referred to a coroner.

We have developed a statistical model to estimate the number of deaths likely to have occurred in each week, based on previous experience of the pattern of registration delays, including the effects of bank holidays. The method is described in the article Predicting total weekly death occurrences in England and Wales: methodology and the results are shown in the tab, “Estimated total deaths 2020”, of the accompanying dataset.

These figures are different from the daily surveillance figures on COVID-19 deaths published by the Department of Health and Social Care (DHSC) on the GOV.UK website, for the UK as a whole and its constituent countries. Figures in this report are derived from the formal process of death registration and may include cases where the doctor completing the death certificate diagnosed possible cases of COVID-19, for example, where this was based on relevant symptoms but no test for the virus was conducted.

From 29 April 2020, the DHSC started to publish as their daily announced figures on deaths from COVID-19 for the UK a new series that uses improved data for England produced by Public Health England (PHE). These figures provide a count of all deaths where a positive test for COVID-19 has been confirmed, wherever that death has taken place – a change from previously reporting only confirmed COVID-19 deaths in hospitals.

Figures for Scotland, Wales and Northern Ireland had already begun to include deaths outside hospitals, so this change ensured that the UK-wide series had a shared and common definitional coverage. A statement was published by the Office for National Statistics (ONS), which provides more detail of the changes.

On 12 August 2020, the PHE data series was revised to include two measures: deaths of positively tested individuals where the death occurred within 28 days and deaths within 60 days of a positive test. More information on these changes can be found in their technical summary (PDF, 854KB).

In contrast to the GOV.UK figures, we include only deaths registered in England and Wales, which is the legal remit of the ONS. Tables 2 and 3 provide an overview of the differences in definitions between sources.

From the week ending 26 February 2021 (Week 8), new International Classification of Diseases (ICD-10) codes for COVID-19 issued by the World Health Organization (WHO) have been implemented for deaths involving COVID-19. The new codes are U09.9 (Post-COVID condition, where the acute COVID had ended before the condition immediately causing death occurred) and U10.9 (Multisystem inflammatory syndrome associated with COVID-19 (also called Kawasaki-like syndrome), a specific, uncommon effect of COVID-19 in children). These are in addition to the existing codes of U07.1 (COVID-19, virus identified) and U07.2 (COVID-19, virus not identified, that is, COVID-19 stated to be unconfirmed or suspected).

We will publish accompanying articles periodically, giving enhanced information such as age-standardised and age-specific mortality rates for recent time periods and breakdowns of deaths involving COVID-19 by associated pre-existing health conditions.

There is usually a delay of at least five days between occurrence and registration. More information on this issue can be found in our impact of registration delays release.

Our User guide to mortality statistics provides further information on data quality, legislation and procedures relating to mortality and includes a glossary of terms.

Figures are based on the date the death was registered, not when it occurred. There is usually a delay of at least five days between occurrence and registration. More information on this issue can be found in our impact of registration delays release.
