Description:
Age-specific death rates as a percentage of rates in 1991. Extracted from Health Statistics Quarterly 14 - Report: Death registrations in England and Wales: 2001, causes.
This report gives numbers of deaths registered in England and Wales in 2001 by age and sex, and for selected underlying causes of death. It also compares death rates by sex and age with those for deaths which occurred in 1999 and 2000. The year 2001 is the first in which cause of death has been coded according to the Tenth Revision of the International Classification of Diseases (ICD-10).
Deaths by sex and age of deceased
* A total of 532,498 deaths were registered in 2001, compared with 537,877 registered in 2000, a decline of 1.0 per cent.
* The number of male deaths fell by 1.2 per cent and female deaths by 0.8 per cent between 2000 and 2001.
Figures 1 and 2 show the relative change between 1991 and 2001 in age-specific death rates for males and females respectively. The long-term decline in death rates continued for most sex/age groups. The relative fall between 1991 and 2001 was most pronounced at ages 1 to 14 for both sexes. There was comparatively little decline in mortality rates at ages 15 to 44 and 85 and over during the ten-year period. Male death rates declined more than female rates in every aged group shown. However, absolute mortality rates remain higher in males for every age group.
Explanatory notes
Coding of underlying cause of death
Since January 2001 cause of death has been coded to the Tenth Revision of the International Classification of Diseases (ICD-10) (see references 1, 2 and 3 below). This was introduced on the recommendation of the World Health Organization (WHO) and replaced the Ninth Revision (ICD-9) (see references 4 and 5 below) which have been in use since 1979. The major changes have been described in detail in Health Statistics Quarterly 08 and 13 (see references 6 and 7 below). In order to help quantify the changes, ONS has carried out a bridge coding study. All deaths registered in 1999 were independently coded to both ICD-9 and ICD-10 and the causes in each revision compared using internationally agreed groups of equivalent codes. The results can be found in the Report 'Results of the ICD bridge coding study, England and Wales, 1999' in this publication (see reference 8 below).
Cause of death is assigned by an automated coding system with the exception of deaths due to external causes (ICD-10 codes V01-Y89). These are coded clerically using information from coroners' certificates (including inquest verdicts) to produce consistent figures on suicides, homicides, and other deaths not from natural causes.
Occurrences and registrations
* The first annual extract from our deaths database, produced in April following the data year, comprises registrations in that year. Outputs produced using this extract include this Report and an area based Report in Population Trends, as well as the annual VS tables and the Compendium of Clinical and Health Indicators.
* The second extract is produced in the September following the year to which it relates, and comprises occurrences in the data year. This extract forms the basis for the annual mortality reference volumes in the DH series.
