One in four victims of domestic violence in part of West Yorkshire are aged over 50, new figures show.
Kirklees Council says 2,000 people contact its domestic violence team each year and 500 of those are over 50.
The oldest person it has dealt with is an 84-year-old woman who was regularly beaten by her husband.
The authority, which covers Huddersfield, Dewsbury and Batley, said it wanted to highlight the issue of domestic violence among older people.
Thelma Singleton, the council's domestic violence team manager, said the 84-year-old was beaten and controlled by her husband.
She said: "She had to get permission to go out shopping... family and friends were excluded from her home - the home that she shared with her husband - and one day she suddenly decided she'd had enough.
"She's fine. With the help of Kirklees housing she's been rehoused and she gets support. She's making a fresh start."
Mrs Singleton said a whole generation of older women do not report abuse because they do not know how to get help.
"Domestic violence is now frequently talked about and it's on television, it's in the soaps, it's in magazines.
"That's not available as an option to find out information for some of these women," she said.
"When they report and ask for help to face their future their future is so different from, say, a younger woman.
"We are thinking of people who are planning their retirement or who are already in retirement who have lived with this secret for years and years."
