Death rates by age-group and gender
Posted: Sat Feb 08, 2025 9:04 am
The first study examined the death rates by age-group and gender for each travel mode in England in 2007-2009.
We were provided with NTS data for how much travel people in each age-sex group in England did per year, for the three years combined. We then looked up the mid-year population estimates for England for each of those years. We added up the number of people in each age-sex group for each year, then multiplied that by the average israel rcs data annual travel to obtain a total number of billion kilometres (bnkm) travelled for each travel mode.
The number of deaths by mode came from ONS mortality data, provided by Public Health England, aggregated over the three years and by age-sex group using the ICD-10 (International Classification of Diseases, 10th iteration) external codes we provided for drivers, pedestrians, and cyclists killed in a crash or fall on a public road.
We calculated the death rate for cyclists, drivers, and pedestrians by dividing the number of deaths for each travel mode by the distance travelled, to obtain deaths per bnkm for each age-sex group for each travel mode. We also tried to look at death rates by time spent travelling. We did not know that time was available in the NTS, so applied the average speed by mode to the distances travelled by mode. This was of course very inaccurate as men generally walk and cycle (and drive?) faster than women; older adults and children walk and cycle more slowly than young and middle-aged adults.
