In the UK, one woman is killed by a man every three days. Men's violence against women is a leading cause of the premature death for women globally but research in the UK and Europe is limited and unconnected.

The Femicide Census significantly improves upon currently available data by providing detailed comparable data about femicides in the UK since 2009, including demographic and social factors and the methods men selected to kill women. By collating femicides, the census has shown that these killings are not isolated incidents, and many follow repeated patterns.

The Femicide Census is a unique source of comprehensive information about women who have been killed in the UK and the men who have killed them - as such it makes a vital contribution to improving knowledge, strategy, policy and practice, including raising awareness; creating a resource for academics, journalists, policymakers and others researching femicide; identification of state failings; and remembering and raising the status of women killed by men.

Treebeard has provided core funding to the Femicide Census since 2017.
