Of those killed and seriously injured, 72% were men, while 22% of casualties were aged 16 to 24.
However, there was a 37% decrease in the number of casualties of people under the age of 16.
Covid saw traffic levels decrease, with the number of cars and taxis on the road falling by 26% and the number of bus and coach journeys halving in 2020, according to Department for Transport figures.
