2. Death registrations in Quarter 4 2019

In Quarter 4 (Oct to Dec) 2019, there were 129,821 deaths registered in England. This was 8,674 more deaths than Quarter 4 2018 and 6,752 more deaths than the five-year average (2014 to 2018) for this quarter. Of the deaths registered in Quarter 4 2019, the number of male deaths was 64,264 (60,304 in 2018) and female deaths was 65,557 (60,843 in 2018).

When we are looking at comparisons over time, we express the number of deaths registered as age-standardised mortality rates. Since Quarter 4 2001, age-standardised mortality rates had statistically significantly decreased from 1,229.6 deaths per 100,000 population to a low of 902.0 deaths per 100,000 in Quarter 4 2018. However, the rate of decline in the mortality rate had been slowing since 2011 and in Quarter 4 2019 the age-standardised mortality rate statistically significantly increased to 948.1 deaths per 100,000. This is the first increase in Quarter 4 mortality rate since 2016 and a similar rate to that seen in 2017 (Figure 1).

    Age-standardised mortality rates, by sex and age group, in Quarter 4 2019

    Most deaths registered typically occur in those who are aged 75 years and over. For this reason, age-standardised mortality rates for those aged under 75 years and those aged 75 years and over have been analysed separately. A total age-standardised mortality rate was analysed for those aged 0 to 74 years, then age-specific mortality rates were analysed for ages 75 to 79 years, 80 to 84 years, 85 to 89 years, and 90 years and over.

    Generally, since 2001, the age-standardised mortality rate of both males and females aged 0 to 74 years had been decreasing. However, the mortality rate for females aged 0 to 74 years in Quarter 4 2019 increased compared to Quarter 4 2018 (255.8 deaths per 100,000 compared to 253.3 deaths) whereas for males it decreased slightly (386.5 deaths per 100,000 males in 2018 to 386.0 deaths in 2019). This marks the first increase in Quarter 4 since 2013, for females under the age of 75, and narrows the difference in mortality rates between males and females (Figure 2).

    Figures 3 and 4 show that age-specific mortality rates had been generally decreasing among those aged 75 years and over, with Quarter 4 2018 recording the lowest mortality rates seen since the data series began in 2001. However, there were statistically significant increases in mortality rates in Quarter 4 2019, for both males and females, in all age groups 75 years and over. The mortality rate for those aged 90 years and over has fluctuated year-on-year since 2009 making findings difficult to interpret.

    3. Provisional annual death registrations

    To monitor year-to-year mortality rates, we have calculated provisional annual mortality rates based on the number of deaths registered between 1 January and 31 December from 2001 to 2019. The finalised annual death registrations for 2019 will be presented in the updated Death registrations publication, expected in summer 2020.

    In 2019, there were 496,354 deaths registered in England, a decrease of 9,505 deaths compared with 2018 and the lowest number registered since 2016. The end of year age-standardised mortality rate for 2019 has also statistically significantly decreased to 919.8 deaths per 100,000 population from 956.3 deaths in 2018. This sharp decrease in the annual mortality rate in comparison with 2018 was driven by the statistically significantly lower mortality rates from Quarter 1 (Jan to Mar) 2019 and Quarter 2 (Apr to June) 2019 in comparison with the same quarters from 2018 (Figure 5).

    Further age-standardised mortality rates have been created for rolling five-year periods to reduce the variance that can occur between individual years. When comparing the 2019 annual mortality rate (919.8 deaths per 100,000 population) to the previous five-year average from 2014 to 2018 (961.6 deaths per 100,000 population) the decrease is statistically significant (Figure 5).

    4. Death occurrences in Quarter 4 2019

    This section is based on the date a death occurred, rather than the date of registration as in the previous sections, to monitor current mortality trends in England. Analysis of deaths by date of registration is useful as the data are comparable across time and geography.

    Because of the length of time that it takes a death to be registered, it can mean that we are not monitoring current death trends. For example, a death registered in Quarter 4 (Oct to Dec) 2019 could have occurred in a previous quarter or even a previous year. Further information regarding death occurrences and registration delays can be found in the most recent Impact of registration delays publication.

    Between 1 October and 31 December 2019 there were 125,950 deaths that occurred in England, 2,274 fewer than the five-year average (2014 to 2018) for that quarter. It is important to note that the number of death occurrences is incomplete as it is likely more deaths need to be registered, therefore all data within this section is likely to change and interpretations should be treated with caution.

    Figure 6 displays the number of deaths occurring per day in Quarter 4 2019 compared to the five-year average (Q4 2014 to 2018). It also shows the range of death occurrences for each day, which refers to the difference between the lowest and highest number of deaths observed on each day during Quarter 4 in 2014 to 2018. The highest number of deaths in Quarter 4 2019 occurred on the 19 December (1,634 deaths) and the lowest number of deaths occurred on the 2 October (1,131 deaths).

    Where the number of death occurrences on an individual day fell outside of the range from the previous five years, it is likely due to one of two reasons. First, is that the most recent figures used for analysis were incomplete. This could be a result of the death occurring close to the end of the period and not leaving enough time to be registered before the data extract was created. Second, could be that there was an external influence that affected the data on individual days, such examples include extreme weather or an illness epidemic.

    5. Annual (provisional) underlying cause of death registrations in 2019 for those aged 75 years and over

    The annual provisional age-standardised mortality rates of circulatory diseases, influenza and pneumonia and all other respiratory diseases statistically significantly decreased in 2019, for both females and males, in comparison to 2018. The age-standardised mortality rates in 2019 for these causes are all the lowest they have been since 2001 (Figures 7a and 7b). The 2019 decrease in mortality rate for influenza and pneumonia however was somewhat expected due to the elevated prevalence of influenza and pneumonia in 2018.

    When observing Dementia and Alzheimer’s disease, the annual mortality rate for females also statistically significantly decreased (1392.1 deaths per 100,000 in 2018 to 1283.9 deaths in 2019). Similarly, the mortality rate for ‘all other causes’ for females in 2019 statistically significantly decreased to 1254.1 deaths per 100,000 compared to 1310.8 deaths in 2018. Decreases in annual mortality rates for these two causes were also seen for males when compared to 2018, however the decreases were not statistically significant. The mortality rates in 2019 for Dementia and Alzheimer’s are the lowest they have been, for both sexes, since 2016.

    Cancer was the only underlying cause we examined where neither males nor females experienced a statistically significant difference in mortality rates between 2018 and 2019. For males, the mortality rate decreased from 2051.6 deaths per 100,000 in 2018 to 2020.5 deaths in 2019 and for females increased from 1254.8 deaths per 100,000 in 2018 to 1256.2 deaths in 2019. This is the first occasion the mortality rate for cancer has increased for females, aged 75 and over, since 2012.

    Provisional life expectancy in 2019

    Provisional estimates of life expectancy at birth have increased for both males and females in 2019 (79.9 years for males and 83.6 years for females) in comparison with 2018 (79.6 for males and 83.2 for females respectively).These estimates are the new highest life expectancy figures recorded.

    For males, provisional life expectancy estimates reported increases in 2019 of 0.3 years at 65 years and 0.2 years at 75, 85 and 95 years compared with 2018. Similarly, female life expectancy estimates in 2019 increased, by 0.3 years at ages 65, 75 and 85 years, and by 0.1 years at age 95 years compared with 2018.

    Single-year life tables should be treated with caution when interpreting due to being typically more volatile in comparison to three-year average life tables. This is because single years are more susceptible to one-off events, such as illness epidemics, which can affect mortality rates for a short period

    The accompanying datasets show life expectancy at birth, age 65, 75, 85 and 95 years, by sex.

    6. Glossary

    Age-standardised mortality rates

    Age-standardised mortality rates are used to allow comparisons between populations, which may contain different proportions of people of different ages. The 2013 European Standard Population is used to standardise rates.

    Age-specific mortality rates

    Age-specific mortality rates are used to allow comparisons between specified age groups.

    Statistical significance

    The term “significant” refers to statistically significant changes or differences. Significance is determined by the 95% confidence intervals, where non-overlapping confidence intervals between figures demonstrate that the difference is unlikely to be a result of random fluctuation. More information is available on our uncertainty pages.

    Annual

    Annual is the period covering 1 January to 31 December.

    Quarter 4

    Quarter 4 is the period covering 1 October to 31 December.

    7. Measuring the data

    The purpose of this article is to provide timely surveillance of mortality in England, based on the best available provisional data. This article focuses on Quarter 4 (Oct to Dec) 2019. Previous quarterly reports are available.

    Deaths data sources

    This article is based primarily on death registrations, with a section on death occurrences following the annual overview. Death occurrences show the number of deaths that occurred within a calendar period and give a better indication than registrations of exactly when deaths were at their highest. This allows mortality to be related to other factors such as weather patterns.

    A provisional extract of death registrations and death occurrences data for Quarter 4 (1 Oct to 31 Dec 2019) was created on 28 January 2020, roughly four weeks after the end of the reporting period.

    Death registrations data for 2019 are provisional; however, we would expect only very small changes to total death registration counts once data are made final.

    Registration delays

    Previously, death occurrences data have been produced using a similar extraction date to ensure the data were consistent throughout the time period. However, for this release and all future releases, this similar extraction date has been removed to ensure the occurrence data we are publishing are the most up to date.

    Because of registration delays, deaths that occurred during Quarter 4 2019 may not have been registered by 31 December 2019 when the data extract was created. For this reason, the quarterly occurrences data are always somewhat incomplete and we would expect the number of death occurrences in Quarter 4 2019 reported in future releases to be higher than the number reported here.

    Quarterly populations

    We publish the mid-year population estimates used for calculating rates. For 2019, the 2018-based Office for National Statistics (ONS) population projections were used.

    Calculation of mortality rates for quarterly deaths requires adjustments to be made to annual population estimates to calculate rates that are comparable with annual rates.

    We calculate an annual population centred on the midpoint of the quarter using two years’ worth of population estimates or projections. This is then multiplied by the number of days within the quarter as a proportion of the total number of days within that year. The output is used as the population denominator in calculations of age-standardised and age-specific mortality rates:

    Quarter 4 2019 population


    where m is the number of days from 1 July 2018 (the start of the mid-year for the population estimate) to the midpoint of Quarter 4 inclusive, N is the number of days in Quarter 4 2019, M is the number of days in 2019 and (i) is the age group.

    Early access for quality assurance purposes

    We provide early access for quality assurance purposes to a small number of analysts within Public Health England (PHE) and Department of Health and Social Care (DHSC). The analysts are not permitted to share the findings or the report more widely in their organisations. The report is provided for the analysts to provide technical comment on our findings. However, ONS itself independently produces these statistics, including determining the focus, content, commentary, illustration and interpretation of these measures presented and the comments provided by PHE and DHSC are purely advisory.

    Quality and methodology information

    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.

    8. Strengths and limitations

    Provisional data are used

    Provisional death registrations and death occurrences data are used in this bulletin. This enables timely analysis to be completed to monitor mortality trends. However, as the data are provisional, they are subject to change.

    Data coverage and timeliness

    Mortality data give complete population coverage. They ensure the estimates are of high precision and are representative of the underlying population at risk. However, because of registration delays, quarterly death occurrence data are always somewhat incomplete. This is especially true for deaths that occurred towards the end of the quarter.

    Further information can be found in the Mortality statistics in England and Wales QMI and the User guide to mortality statistics.
