From the Home Office Impact Assessment -
In 2011, the FMU provided advice or support in almost 1500 cases, but we know that this does not reflect the full scale of the abuse, and many more cases are not reported. Research carried out by the then Department for Children, Schools and Families in 2009 estimated that that the national prevalence of reported cases of forced marriage in England was between 5000 and 8000.1 Forced Marriage cases tend to involve young women and young men although it does impact more on women than men 78% involved female victims and 22% involved male victims. The FMU is aware of cases from, Afghanistan, North and East Africa, Bangladesh, India, Iran, Iraq, Pakistan and Turkey. This list of countries is not exhaustive and there may be other communities in which forced marriage is practised.
As well as there being much higher numbers of female victims, the impact of forced marriage is much greater on women because of their lack of power relative to men. Diana Nammi from The Iranian and Kurdish Women's Rights Organisation in The Guardian -
"Forced marriage is a violation of human rights itself, and can lead to physical violence, imprisonment, rape and even 'honour' killing. Women and girls from minority communities have suffered these violations for too long. The new law will empower them with the knowledge that what is happening to them is wrong and can be stopped."
