Incidence of suicide is under-reported due to both religious and social pressures, and possibly completely unreported in some areas. Nevertheless, from reported cases, certain trends are apparent. Since the data is skewed, comparing suicide rates between nations is statistically unsound. The trends themselves are not the cause, but may be indicative of a root cause.[clarification needed]
A 2006 report by the World Health Organisation (WHO) states that nearly a million people take their own lives every year, more than those murdered or killed in war. WHO figures show a suicide takes place somewhere in the world every 40 seconds. Suicide rates are highest in Europe's Baltic states, where around 40 people per 100,000 die by suicide each year, second in line is in the Sub-Saharan Africa where 32 people per 100,000 die by suicide each year. The lowest rates are found mainly in Latin America and a few countries in Asia.
In most countries the incidence of suicides is higher than the incidence of intentional homicides.
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.
Gender and suicideEdit
In the United States, males are four times more likely to die by suicide than females. Male suicide rates are higher than females in all age groups (the ratio varies from 3:1 to 10:1). In other western countries, males are also much more likely to die by suicide than females (usually by a factor of 3–4:1). It was the 8th leading cause of death for males, and 19th leading cause of death for females. Excess male mortality from suicide is also evident from data from non-Western countries.
Race and suicideEdit
In 2003, in the United States, whites were nearly 2.5 times more likely to kill themselves than were blacks or Hispanics. There is a marked divergence by age as seen in the chart below. In the eastern portion of the world (primarily in Asian or Pacific-Island countries) the numbers of reported suicides is growing every year. Of all ethnic groups in the United States, Native Americans, Multiracial Americans, and Filipino Americans have the highest risk of suicide.
Sexual orientation and suicideEdit
The likelihood of suicide attempts are increased in both gay males and lesbians, as well as bisexuals of both sexes when compared to their heterosexual counterparts. The trend of having a higher incident rate among females is no exception with lesbians or bisexual females and when compared with homosexual males, lesbians are more likely to attempt than gay or bisexual males.
Studies vary with just how increased the risk is compared to heterosexuals with a low of 0.8-1.1 times more likely for females and 1.5-2.5 times more likely for males. The highs reach 4.6 more likely in females and 14.6 more likely in males.
Race and age play a factor in the increased risk. The highest ratios for males are attributed to caucasians when they are in their youthhood. By the age of 25, their risk is down to less than half of what it was however black gay males risk steadily increases to 8.6 times more likely. Through a lifetime the risks are 5.7 for white and 12.8 for black gay and bisexual males. Lesbian and bisexual females have opposite effects with less attempts in youthhood when compared to heterosexual females. Through a lifetime the likelihood to attempt nearly triple the youth 1.1 ratio for caucasion females, however for black females the rate is affected very little (less than 0.1 to 0.3 difference) with heterosexual black females having a slightly higher risk throughout most of the age-based study.
Gay and lesbian youth who attempt suicide are disproportionately subject to anti-gay attitudes, and have weaker skills for coping with discrimination, isolation, and loneliness, and were more likely to experience family rejection than those who do not attempt suicide. Another study found that gay and bisexual youth who attempted suicide had more feminine gender roles, adopted an LGB identity at a young age and were more likely than peers to report sexual abuse, drug abuse, and arrests for misconduct.
One study found that same-sex sexual behavior, but not homosexual attraction or homosexual identity, was significantly predictive of suicide among Norwegian adolescents. In Denmark, the age-adjusted suicide mortality risk for men in registered domestic partnerships was nearly eight times greater than for men with positive histories of heterosexual marriage and nearly twice as high for men who had never married.
Social factors and suicideEdit
Higher levels of social and national cohesion reduce suicide rates. Suicide levels are highest among the retired, unemployed, impoverished, divorced, the childless, urbanites, empty nesters, and other people who live alone. Suicide rates also rise during times of economic uncertainty (although poverty is not a direct cause, it can contribute to the risk of suicide). Epidemiological studies generally show a relationship between suicide or suicidal behaviors and socio-economic disadvantage, including limited educational achievement, homelessness, unemployment, economic dependence and contact with the police or justice system. War is traditionally believed to be associated with a fall in suicide rates, however this has been questioned in recent studies, showing a more complex picture than previously conceived.
Health and suicideEdit
An unknown amount of suicide fatalities are misdiagnosed as consequences of severe illness.
Season and suicideEdit
The idea that suicide is more common during the winter holidays (including Christmas in the northern hemisphere) is actually a myth, generally reinforced by media coverage associating suicide with the holiday season. The National Center for Health Statistics found that suicides drop during the winter months, and peak during spring and early summer. Considering that there is a correlation between the winter season and rates of depression, there are theories that this might be accounted for by capability to commit suicide  and relative cheerfulness. Suicide has also been linked to other seasonal factors.
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.
Certain time trends can be related to the type of death. In the United Kingdom, for example, the steady rise in suicides from 1945 to 1962-63 was probably to some extent curtailed following the removal of carbon monoxide from domestic gas supplies which occurred with the change from coal gas to natural gas during the sixties. Methods vary across cultures, and the easy availability of lethal agents and materials plays a role.
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.

Suicide rates are shown to be higher in low religious environments.
