Cycling in Britain is often perceived as dangerous, but how much have the risks of riding a bike changed, and how do they compare with driving a car, asks statistician Jamie Jenkins.
There has been a huge fall in the number of deaths among cyclists in the past 80 years.
The figure reached its peak in 1934, when 1,536 pedal cyclists died in Great Britain. Last year there were 109 fatalities, according to the Department for Transport (DFT), and it's important to remember that there were considerably fewer people living in the country 80 years ago.
But before we think that 1934 was a bad year for cycling, remember that despite the lower population there are likely to have been far more cyclists. Owning a motor vehicle was much rarer and thus cycling as a primary means of transport would have been more common.
We do not know exactly how many cyclists there were in 1934, and indeed the figures today are pretty sketchy, but the number of cars on the road is considered to be a pretty good indicator. In 1934 there were fewer than two million cars on Britain's roads, while today there are about 28 million licensed cars.
So how safe is it to cycle on Britain's roads in 2014?
