- Research has found that, with an estimated 87.5 suicides per 100 000 deaths, Lesotho has the highest suicide rate in the world.
- In Africa and South Asia, a 'low share' of deaths were registered as suicides, meaning the published data could be lower than actual cases.
- South African men are 4.1 times more likely to die by suicide than women.
New research by Our World in Data has found that southern Africa has some of the highest suicide rates in the world.
The data is from 2019, before the Covid-19 pandemic shut the world down. In the top 10 of the world's highest suicide rates per 100 000 people, Lesotho recorded 87.5 deaths, Eswatini comes in third with 40.5 and Zimbabwe is seventh with 23.6, followed closely by South Africa with 23.5. Mozambique is ninth with 23.2 deaths and the Central African Republic rounds off the top 10 with 23 deaths.
With 458 deaths per 100 000, Nigeria has the highest number of suicide deaths by use of firearms in Africa, followed by South Africa with 397 deaths, the Democratic Republic of the Congo with 395, Ethiopia with 340 and Tanzania with 203.
Our World in Data said the major contributing factors for suicide included "differences in underlying mental health and treatment, personal and financial stress, restrictions on the means of suicide, [as well as] recognition and awareness of suicide".
The findings were based on death certificate data from 2019 which were "classified under death codes for 'intentional self-harm' in the International Classification of Diseases", the report said.
The researchers, however, said in Africa and South Asia, a "low share" of deaths were registered as suicides, which means the published data could be lower than actual cases.
