Greater London Authority provides data on Excess Winter Deaths (EWD) by age and underlying cause of death for London boroughs. The dataset is based on pooled data from 2004 to 2011, with trends calculated using three-year averages. It uses the ONS method to define winter mortality, calculating an index from deaths occurring between December and March.
Use Cases
- Analyze seasonal mortality disparities across London boroughs based on geographic and demographic data.
- Investigate the relationship between age and excess winter mortality based on the age-group breakdown mentioned.
- Study trends in cause-specific winter deaths over time based on the underlying cause of death data.
- Calculate and compare Excess Winter Mortality Indexes for different population subgroups based on the described ONS method.
Strengths
- Data covers a 7-year period from 2004 to 2011, providing a multi-year baseline.
- Includes breakdowns by age and underlying cause of death, allowing for demographic and epidemiological analysis.
- Calculations follow a standardized ONS methodology for defining winter periods and excess mortality.
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
- Column-level documentation is absent; field semantics must be inferred after download.
- The index calculation is not age-standardized, which may affect comparisons between areas with different age profiles as noted in the description.
