It is probable that the incidence of suicide is widely under-reported due to both religious and social pressures, and possibly completely unreported in some areas. Nevertheless, from the known suicides, certain trends are apparent. However, since the data is skewed, attempts to compare suicide rates between nations is statistically unwise. The trends themselves are not the cause, but may be indicative of a root cause.
In 1998, the World Health Organization ranked suicide as the twelfth leading cause of death worldwide.
As many as 60,000 people commit suicide in Russia every year; approximately 30,000 people die by suicide each year in the United States; over 30,000 kill themselves in Japan; and about 250,000 commit suicide each year in China. In western countries men commit suicide at four times the rate of women. Women are more likely to attempt suicide than men. The countries of the former Soviet Bloc have the highest suicide rate in the world. The region with the lowest suicide rate is Latin America. Up to at least the 1950s, it was the Republic of Ireland which had the lowest suicide rate in the world, as reported by an Irish TV news report in 2007. In India, suicide rates for women are nearly three times higher than those for men. Higher suicide rates among women have been reported in China.
According to the National Institute of Mental Health, suicide contagion is a serious problem, especially for young people. Suicide can be facilitated in vulnerable teens by exposure to real or fictional accounts of suicide, including media coverage of suicide, such as intensive reporting of the suicide of a celebrity or idol.
Excess male mortality from suicide is also evident from data from non-Western countries. In 1979-81, out of 74 countries with a non-zero suicide rate, two reported equal rates for the sexes (Seychelles and Kenya), three reported female rates exceeding male rates (Papua-New Guinea, Macau, and French Guiana), while the remaining 69 countries had male suicide rates greater than female suicide rates.
While there are more completed male suicides than female, females are more likely to attempt suicide. One possible explanation of this statistical phenomenon, supported by a study by Rich, Ricketts, Fowler, and Young, is that males tend to use more "violent, immediately lethal methods of suicide" than females.
An unknown amount of suicide fatalities are misdiagnosed as consequences of severe illness.
The variation in suicides by day of week is actually greater than any seasonal variation. In the United States, more people die by suicide on Monday than any other day; Saturday is the day with the least number of suicides.
It is estimated that global annual suicide fatalities could rise to 1.5 million by 2020. Worldwide, suicide ranks among the three leading causes of death among those aged 15-44 years. Suicide attempts are up to 20 times more frequent than completed suicides.
Several groups have a greater than average incidence of suicide. These high-risk groups usually are indicative of a larger problem leading to their decision.
These groups include:
Many theories have been developed to explain the causes of suicide. Psychiatric theories emphasize mental illness. Psychological theories emphasise personality and poor coping skills, while sociological theories stress the influence of social and environmental pressures.
Today, most social scientists believe that a society's unity can influence suicide deaths. Emile Durkheim claimed that greater social integration translates to fewer suicides. Suicide rates among adults are lower for married people than for divorced, widowed, or single people, a statistic confirming Durkheim's argument.
Social influences such as economic cycles with high unemployment rates, influence of religion, acceptance, and peer pressure all play a factor. For example, suicide rates were abnormally high during the Great Depression in America.
Genetic and biological factors play a large role in suicide likelihood. Research has shown that suicidal behaviour runs in families. A notable example are the suicides of the Hemingway family in which five members committed suicide. In 1985, the American Journal of Medical Genetics studied an Amish community in Pennsylvania. The studies revealed that four families, representing only 16 percent of the total Amish population, accounted for 73 percent of all Amish suicides. Some scientists claim 10 to 15 genes account for triggering suicide attempts. Similarly how depression is linked genetically, family ties may also have a large effect on one's suicide risk.
In the early 1900s Austrian psychoanalyst Sigmund Freud developed some of the first psychological theories of suicide. Karl Menninger followed up on this principal theory and suggested that all suicides have three interrelated emotions: revenge, depression, and guilt. Edwin Shneidman argues victims of suicide show a sense of unbearable psychological pain, a sense of isolation, and the perception that death is the only solution to their problems.
Theories of the effects of age on suicide have changed over time. Initially, it was believed that across all demographic populations, suicides increased with age. However, new research indicates that while this is true for men, suicide rates in women rate peak around the age of 35, plateau and only decline past the age of 85.
Theories about the effects of social status on suicide rates are diverse. This is partly due to difficulty in quantifying social status. Some theorists believe that suicide rates increase in direct proportion to social status. Others believe that the inverse is true.
Socio-economic factors such as unemployment, poverty, homelessness, and even discrimination trigger such suicidal thoughts. It's also noted that poverty may not be a direct cause but it can increase the risk of suicide, as it is a major risk group for depression. Discrimination and bullying is another major factor in suicides, as bullying and discrimination can lower self-esteem which could lead to depression and then suicide.
Suicide is more common among alcoholics, especially after loss of intimate relationships, such as the death of a spouse, divorce, loss of a friend and parental alienation. However, it is difficult to ascertain whether suicide and experience of loss by an alcoholic are causally related, since no data regarding causal relationships between alcoholism itself and suicide exists.
Terminal illness has not been shown to be directly linked to higher suicide rates. Despite this, physical illness is found in nearly half of suicides.
Divorced or separated men commit suicide 4 times more than women.
On an individual level, the driving forces behind suicide vary across a range of themes. Common intentions behind suicidal actions include those of guilt, remorse, escapism and the provoking of guilt in those left behind. Media reports or local knowledge of a suicide can trigger copycat suicides in vulnerable people.
De Catanzaro begins to explain suicide by saying that differential reproduction is in fact much more important to evolution than is "survival of the fittest". That is to say, that mere survival is not particularly important to passing on genes. Even if someone is short lived, but reproduces a lot, they are likely to have more descendants than someone who lives a long time but does not reproduce very much. The other factor in explaining from the evolutionary perspective is inclusive fitness. Since an individual will share many genes with their relatives, it is in their evolutionary interest to ensure their relatives' survival and reproduction. More of their genes will be present in subsequent generations.
De Catanzaro believes that a general theory of suicide can be formed based on a calculation of the "costs of an individual's immediate death to the propagation of his or her genes". He developed a very complex equation that takes the various factors of the subject's potential reproduction, such as dependency of children, remaining reproductive potential, dependence on kin, and others, into account and is able to predict the subject's risk for suicide. Current research has been conducted mostly in the United States, with a large portion of the sample being young, educated, and religious.
According to de Catanzaro's variables, those at greatest risk of suicide include the elderly, especially those who are a burden on their family, anyone who is ostracized by their kin, someone unable to provide for their kin, dependent on their reproductively capable kin, or anyone who has difficulty relating with the opposite sex. All of these conditions will lead to emotional and psychological conditions that will make suicide more likely. De Catanzaro cites studies that show that emotions have a physiological basis to show that the self destructive response may be a natural, evolved response to their situation to ensure the continued propagation of one's genes.
According to this theory, those mostly likely to kill themselves would be the elderly dependent on financially pressed children, or someone with little hope of reproducing who is also dependent of kin. Dr. de Catanzaro's theory can also be applied to general self preservation. It can be used to predict how likely a mother or father is to sacrifice herself or himself to save their children, or other situations of that sort. De Catanzaro takes pains to recognize that his formula is only a base on which to predict likelihood of suicide or self sacrifice. He freely acknowledges that suicide is partially a learned behaviour, as is evidenced by the phenomenon of groupings of suicides occurring in short periods of time. He believes that there are many cultural phenomena that will affect any given individual. De Catanzaro also places strong emphasis on the fact that modern expressions of suicide may sometimes be unpredictable because we are in a different environment from that which we evolved in. He believes that there are many more suicides today than there would be in our "natural" environment due to stress and our confrontation with many situations that we have not been selected to deal with.
Another approach explains the differences between the sexes. One theory argues that men die of suicide more often than women because they do not value their lives as much as women. Since men are not essential to the survival of their offspring, and their potential for reproduction is much more varied, men have evolved to be less fearful of taking risks than women have. If a woman under natural conditions were to die, her children would most likely die as well. Therefore women have evolved to be more fearful of death and physical risk than men, and are therefore less likely to die of suicide. Under this theory suicide is just an expression of males' general willingness to take risks. This may be disclaimed by the fact that while men are 400% more likely to successfully commit suicide, the WHO reports that women attempt suicide more often than men.
The means of achieving suicide varies and is greatly influenced by availability, perceived effectiveness and final bodily state. For example, in the United States, firearms are relatively easy to obtain and suicide by this method is four times more common than the next method.
The common means of suicide, roughly in order of use (U.S.), are by gunshot (the so-called "Hemingway solution"), asphyxia, hanging (there is often considerable overlap between hanging and asphyxia due to lack of expertise), drug overdose, carbon monoxide poisoning, jumping from height, stabbing or exsanguination, and drowning.
Physician-assisted suicide (see euthanasia) is typically by a lethal dosage of a prescription drug supplied by the physician. It may be taken orally, by intravenous drip, or infusion pump with a switch operated by the patient.
