Mortality in England and Wales reversed its long-term decline, with 2015 seeing a significant increase in deaths, particularly among the elderly. Dementia was a major reported cause, though interpretation requires caution.
Area of Science:
- Demography
- Public Health
- Gerontology
Background:
- The long-term decline in age-standardised mortality in England and Wales reversed in 2011.
- A significant increase in deaths occurred in 2015, reversing a slight fall in mortality rates between 2013 and 2014.
Purpose of the Study:
- To investigate the reasons behind the increase in mortality observed in England and Wales during 2015.
- To analyze the causes and age groups contributing to changes in life expectancy between 2013 and 2015.
Main Methods:
- Iterative demographic analysis of population data in England and Wales.
- Examination of causes and ages at death to determine impact on life expectancy changes.
Main Results:
- Mortality in 2015 was higher than in any year since 2008, with approximately 30,000 excess deaths compared to the 2006-2014 average.
- Life expectancy at ages over 60 declined between 2013 and 2015.
- Individuals over 85 years old were most affected, with dementias identified as a major contributor, though coding practice changes necessitate cautious interpretation.
Conclusions:
- The long-term trend of declining mortality in England and Wales has been reversed.
- Excess deaths are concentrated in the older population, highlighting potential impacts on health and social care systems.
- While dementia was a primary reported cause, the findings require careful interpretation due to diagnostic and coding variations.
