Specific causes of death

The majority of deaths are due to a few causes of death: cardiovascular diseases, cancer, respiratory diseases, accidents and other acts of violence, as well as dementia. Sex and age influence the ranking of these causes.

Causes of death by age and sex

The ranking of these causes varies according to age. Congenital diseases are the predominant cause of death in the first two years of life. Death between the ages of 2 and 15 is very uncommon but has many causes. The majority of deaths between the ages of 16 and roughly 40 are caused by accidents and suicide. From about the age of 40, cancer is the most common cause of death but is replaced from around age 80 by cardiovascular diseases.

Potential years of life lost

The potential years of life lost are an indication of premature mortality (before the age of 70). Cancer is the leading cause of premature mortality accounting for 28% of years of potential life lost in men and for 47% in women. Accidents and violent deaths are the second most common cause of premature mortality.

Suicide

Suicide challenges society’s fundamental values and each case is extremely distressing for those close to the victim. It is a relatively common cause of death among young people, for whom death due to disease is very rare. The risk of taking one’s life, however, increases with age. Suicide is the cause of death in 16 out of 1000 deaths.
Assisted suicide is a different phenomenon mostly involving seriously ill people who no longer consider their life worth living and who choose when to die. Assisted suicide is the cause of death in 15 out of 1000 deaths.

Cause of death by nationality

A quarter of Switzerland’s resident population are foreign nationals (26% of men and 23% of women). However, this section of the population is considerably younger and therefore has a significantly lower risk of dying. Only around 10% of deaths concern foreign nationals (12% of deceased men and 7% of deceased women). In the case of tuberculosis, stomach cancer, lung cancer (only men) and perinatal causes of death, foreign nationals have higher mortality rates than Swiss nationals, in the case of cardiovascular diseases, dementia, lung cancer (only women) and for accidents and violent deaths their mortality rates are considerably lower.
