Transport for London’s factsheets and reports on collisions and casualties in London can be found here. General reports covering all modes are published annually (first as factsheets then in more detailed reports), while topic-specific factsheets, for example on pedestrians or cyclists only, are less frequent.
The latest factsheet on cyclist casualties was published in November 2010 and reported on casualties in 2009, with breakdowns by borough, age, gender etc. It also includes a table summarising the trend in cycle casualties in London as a whole since 1986. We have extracted the data from this table and added 2010 data from the most recent all-modes factsheet. The chart below shows the trend, and you can download the resulting table in csv from this link.
