It comes as organisations get together to raise awareness for World Suicide Prevention Day, held annually on September 10, today.
Office for National Statistics data shows 18 people were registered as having died by suicide in Mansfield between 2018 and 2020 – the latest available data.
It means the suicide rate in the area was 6.1 per 100,000 people over the period.
In Ashfield, it was 24, giving a rate of 7.1 per 100,000 people, while in Newark & Sherwood, it was 35 people, giving a rate of 11 per 100,000 people.
The national rate across England and Wales of 10.5 deaths per 100,000 people.
Separate figures show the number of suicide deaths registered across the two nations fell by 8.2 per cent from 5,691 in 2019 to 5,224 in 2020 – though the Office for National Statistics warned the decrease may have been caused by several factors including a delay in registrations during the pandemic.
Jacqui Morrissey, Samaritans assistant director of research and influencing, said: “Any life lost to suicide is a tragedy and we know the after-effects of the extraordinary last 18 months will continue to impact people’s lives in the years to come.
“Funding should be made available in the forthcoming spending review for targeted investment in local areas to further develop and deliver practical support services to prevent suicide among groups at the highest risk, particularly middle-aged men.”
Brian Dow, deputy chief executive officer of charity Rethink Mental Illness and co-chairman of the National Suicide Prevention Alliance, said the pandemic had led to an increase in risk factors for suicide, including debt, housing instability and access to care.
He said: “Reform and investment in health, social care and our benefits system, which provide vital support to so many, is critical."
The Local Government Association said suicide prevention was a public health priority and every council had a suicide prevention plan in place.
David Fothergill, LGA community wellbeing board chairman, said: “Councils are already working closely with schools, railway operators, businesses, hospitals and the police to prevent suicide and help those affected by it.
“The forthcoming spending review provides an opportunity to help further strengthen local action to reduce and prevent suicide as we look to build back better from the pandemic and level up the country.”
The Government has pledged to invest £57 million by 2023-24 to support local suicide prevention plans and establish suicide bereavement services.
A Department for Health and Social Care spokeswoman said its mental health recovery action plan targets those most affected by the pandemic.
She said: "The last 18 months have been exceptionally difficult, and we are committed to doing everything possible to reduce suicides and support people’s mental wellbeing."
