Casualties on the roads by severity (Killed/seriously injured or slight injuries) for both child and all casualties by borough since 2004. Casualties by 5 year age group and severity for London and Great Britain. Data presented is for personal injury road traffic collisions occurring on the public highway, and reported to the police, in accordance with the Stats 19 national reporting system. Also available: Casualties on the roads by LSOA, MSOA and Ward by severity for years 2010 to 2014. Incident level data: Casualty data for all road accidents 2010 to 2014 are also available for individual incident level in CSV format (11 MB and 87k rows). There are slight differences between the local authority recorded in the official DFT data and this one, which has been geo-coded using the Easting and Northing of the accident. When an accident happens on a borough boundary it is down to the police officer to decide which borough the accident occured in. However, this data uses uses the centre points of the Easting and Northing provided and this can fall into a different local authority. For this reason, the geography in the geo-coded data is not official but does provide indicative information. Incident level data from 2005 onwards is available from TFL ('data extracts').

Excess Winter Deaths (EWD) by age and conditions (underlying cause of death) expressed as average per year based on 7 years pooled data, 2004-2011. EWD trend expressed as average per year based on 3 years data. The Excess Winter Mortality Index (EWM Index was calculated based on the 'ONS Method' which defines the winter period as December to March, and the non-winter period as August to November of that same year and April to July of the following year. This winter period was selected as they are the months which over the last 50 years have displayed above average monthly mortality. However, if mortality starts to increase prior to this, for example in November, the number of deaths in the non-winter period will increase, which in turn will decrease the estimate of excess winter mortality. The EWM Index will be partly dependent on the proportion of older people in the population as most excess winter deaths effect older people (there is no standardisation in this calculation by age or any other factor). Excess winter mortality is calculated as winter deaths (deaths occurring in December to March) minus the average of non-winter deaths (April to July of the current year and August to November of the previous year). The Excess winter mortality index is calculated as excess winter deaths divided by the average non-winter deaths, expressed as a percentage.
