The statistics have been released to mark National Volunteers Week, from June 1 until June 7.
They show that the number of people volunteering with Samaritans across the UK and Ireland reached a 10-year high of 21,200 last year.
The charity answered a total of 5.23 million calls for help via telephone, email, SMS, letters and face-to-face support.
Across Yorkshire and Humberside, the charity’s 1,534 volunteers answered 437,938 calls for help.
Marianne Tharby, director of Leeds Samaritans, said: “I am so grateful to our volunteers in Leeds. We are incredibly proud to run our branch 24/7, 365 days a year and we simply wouldn’t exist without the commitment of these generous people.
“I want to thank them all for their hard work and dedication. We know that our callers benefit from having a real person at the end of the line, someone who is trained to really listen to them.
“As we take this week to recognise our volunteers, I also want to encourage those who might be considering joining us to come to one of our information evenings to find out more about volunteering.”
