A Cornish charity is warning that a rise in the number of rape allegations recorded by police in Cornwall and Devon does not paint the whole picture.
New figures by the Home Office show there were almost 1000 in twelve months.
That is around three a day.
Maggie Parks speaks for the Women's Rape and Sexual Abuse Centre in the Duchy.
She says only about fifteen per cent of victims want to report it.
She said: "There is a whole community of people out there who do want to talk about what has happened to them, but don't want to go through he criminal justice process.
"For a lot of people, the criminal justice system doesn't always give them justice. One of the things we know is that only about six per cent of people who do report a serious sex offence or a rape actually see their perpetrators convicted."
The figures are among different sets of data from organisations across the criminal justice system and published by the Rape Monitoring Group.
It says: "The RMG publishes these area digests so that police and crime commissioners, police, prosecutors and agencies within the system have a broad set of data to enable a fuller and more thorough analysis of how rape is dealt with in their local area."
According to the Home Office statistics, 671 rape allegations recorded by officers Duchy and Devon in 2015/2016 were against adults and 326 were against children.
131 cases were referred to the Crown Prosecution Service and, out of those, there were 69 charges.
Separate figures from the Ministry of Justice show in 2015, 77 people were prosecuted and 41 were convicted.
