Infant mortality outputs review
BackgroundThis consultation outlines proposed changes to the annual infant mortality statistics published by the Office for National Statistics (ONS) and outlines future plans. Feedback from users is encouraged.
ONS publishes annual infant mortality statistics for England and Wales in a number of key outputs:
Childhood mortality in England and Wales
Birth cohort tables for infant deaths, England and Wales
Pregnancy and ethnic factors influencing births and infant mortality, England and Wales, England (only) and, Wales (only)
Unexplained deaths in infancy, England and Wales
Death registration summary tables for England and Wales
Deaths registered in England and Wales (Series DR)
The release of these outputs varies depending on timing of the extracts used and the availability of final data from Scotland and Northern Ireland to compile UK data.
To ensure the publication of more timely and fit for purpose final figures, ONS is proposing to change the extracts used in the creation of the publications; this will streamline the outputs and ensure users have the most suitable cross tabulations available to them.
The section titled ‘Why do ONS want to change the number of outputs?’ provides more information on the reasons behind this proposal.
Consideration also needs to be given to the content of the future releases to ensure they meet user needs, are in line with disclosure control guidance and provide a sufficient level of information to inform decisions.
About infant mortality statisticsChildhood and infant mortality statistics are based on information recorded when deaths are certified and registered. The annual total of deaths occurring in a calendar year is taken from the standard dataset for death occurrences created from the deaths database. This annual extract is taken approximately 10-11 months after the end of the data year to allow for late registrations. Although there will be a small number of deaths not registered when the annual extract of death occurrences is taken, delaying the timing of the extract any further will delay the publication of the data.
The birth cohort tables for infant death represent those babies born in a calendar year who died before their first birthday.
Office for National Statistics 3
Infant mortality outputs review
The statistics in the pregnancy and ethnic factors influencing birth and deaths release are based on babies born in a calendar year (whose birth registration have been successfully linked to their birth notification) who died before their first birthday. Linking to the birth notification enables additional analysis on ethnicity and gestation. Further information on birth notifications can be found in the User guide to birth statistics.
Unexplained deaths in infancy are those that have occurred in a calendar year. It includes sudden infant deaths and infant deaths where the causes remained unascertained after a full investigation. Further information can be found in the unexplained deaths in infancy quality and methodology information document.
Mortality data is linked to births data so that information about the parents (collected at the birth registration) can be used for analysis by certain risk factors; these include birthweight, mother’s age at birth of child, mother’s country of birth, marital status, parity (number of previous children) and the parent’s socio economic status based on occupation.
Further information on childhood and infant mortality can be found in the User guide to child mortality statistics and child mortality statistics quality and methodology information document.
Infant mortality statistics presented in deaths registered in England and Wales are based on information recorded when deaths are certified and registered. The annual total of deaths registered in a calendar year is taken from the standard dataset for death registrations created from the deaths database. This annual extract is taken approximately 4 months after the end of the data year. Further information can be found in the User guide to mortality statistics and mortality statistics quality and methodology information document.
Why do ONS want to change the number of outputs?
As mentioned in the previous section, the timing of the release of outputs are dependent on the timings of the extracts (please see annex C for a comparison on the numbers of deaths).
Childhood mortality in England and Wales (published approximately 14-15 months after the end of the reference year). This release is based on final death figures that have occurred in a calendar year. Deaths are further linked to their birth registration where possible to enable analysis by certain risk factors such as, birthweight, age of mother and marital status.
Birth cohort tables for infant deaths, England and Wales (published approximately 26-27 months after the end of the reference year). This release is based on birth figures that have occurred in a calendar year where the baby has died before their first birthday (either in the same reference year or the following year). These birth registrations are linked to their corresponding death registration taken from the final death occurrence extract.
Pregnancy and ethnic factors influencing births and infant mortality, England and Wales, England and, Wales (published approximately 20 months after the end of the reference year). This release is based on births that have occurred in a calendar year where the baby has died before their first birthday (either in the same reference year or the following year). These birth registrations are linked to their corresponding birth notification and their corresponding death registration taken from a provisional death occurrence extract.
Office for National Statistics 4
Infant mortality outputs review
Death registration summary tables for England and Wales (published approximately 7 months after the end of the reference year). This release is based on final death figures that have been registered in a calendar year.
Deaths registered in England and Wales (Series DR) (published approximately 11 months after the end of the reference year). This release is based on final death figures that have been registered in a calendar year. It contains more detailed cause of death detail for those aged 28 days and over.
Due to the timings of the extracts and the linkage that is carried out, there are different infant and child mortality figures across publications which can be confusing for users.
To ensure the publication of more timely and fit for purpose final figures, ONS is proposing to change the extracts used in the creation of the publications; this will streamline the outputs and ensure users have the most suitable cross tabulations available to them.
The feedback received from users will drive any changes made to the annual publications. We do not anticipate any delays in publishing times. However, this cannot be guaranteed as any changes may increase the time taken for processing and quality assurance of figures.

Your requirements of cause of death for perinatal deaths (infants and stillbirths)
In England and Wales, stillbirths and neonatal deaths are registered using a special death certificate which enables reporting of relevant diseases or conditions of both the infant and the mother.
As there is no underlying cause available for these deaths, ONS has developed the ‘ONS cause groups’. This is a hierarchical classification system that groups deaths into broad cause groups based on the causes mentioned on the death certificate. This allows for comparisons and further analysis.
More information and the categories used can be found in the user guide to child mortality statistics.

Annex D – Death registrations vs. death occurrencesThe annual death registration dataset is taken approximately 3-4 months after the end of the reference year. The annual number of deaths that are registered in a calendar year can include deaths that have not occurred in that calendar year due to the timing of the death and delayed registrations (table below). The delay in registering a death is due to the death being referred to a coroner. Further information on the impact of registration delays for a range of causes can be found on our website.
Year Number of registrations
Number registered which occurred in that year
Percentage of those registered that occurred in that year
Number registered which occurred in previous years
Percentage of those registered that occurred in previous years
2014 (All ages) 501,424 477,752 95.3% 23,672 4.7%
2015 (All ages) 529,655 504,483 95.2% 25,172 4.8%
2014 (Infant) 2,689 2,244 83.5% 445 16.5%
2015 (Infant) 2,721 2,335 85.8% 386 14.2%
The first publication based on death registrations is approximately 7 months after the end of the reference year. Annual data based on death registrations allows the output of more timely mortality data
For a final annual extract of death occurrences to be acceptably complete, it is taken approximately 10-11 months after the end of the reference year to allow for any late registrations. However, there are some late registrations that are not included in the annual death occurrence dataset (table below).
Year death occurred Number of late death registrations (all ages) not included in the occurrence dataset (as of April 2017)
Number of late death registrations (infant) not included in the occurrence dataset (as of April 2017)
2013 2,916 118
2014 2,627 91
The first publication based on final death occurrences is approximately 14-15 months after the end of the reference year. The annual occurrence dataset allows for seasonal analysis of mortality data and more detailed infant mortality outputs.
