2001 to 2011 - cyclist numbers change significantly
I've already mapped the changes in cycle use by share of commuting trips in highway authorities.
Other maps showing the changes by district authority, and other modes, such as the changes in car commuting, are also available.
Changes in the number of people cycling is another way of looking at the Census data. Since 2001 there have been huge increases in the number of people who cycle in urban areas, especially London, Brighton, Manchester and Newcastle.
In many rural areas and small towns (especially in the east) there is still a culture of cycling, but even here, there is a rapid decline in the number of people cycling.
What else do we learn from this? The change in London has been profound, but other locations have also seen huge increases in cycling.
Brighton has seen a 118% increase in the numbers of cyclists, and the local authority is busy building innovative cycle facilities, reducing speeds and increasing permeability for cyclists - all measures which should maintain this growth.
On the other hand North Norfolk - a rural district - saw a 37% decrease in the number of cyclists. Yet just a few miles away, in Norwich, the number of cyclists increased by 19%. In other words, policies to increase cycling are working in urban locations, but cycling's rapid decline in other rural and suburban locations may be masking this.
