The population of the United Kingdom was estimated at almost 67.6 million people in 2022. It is the 21st most populated country in the world and has a population density of 279 people per square kilometre, with England having significantly greater density than Wales, Scotland, and Northern Ireland. Almost a third of the population lives in south east England, which is predominantly urban and suburban, with 8.9 million in the capital city, London, whose population density was 5,640 inhabitants per square kilometre (14,600/sq mi) in 2022.
Samaritans is a registered charity aimed at providing emotional support to anyone in emotional distress, struggling to cope or at risk of suicide throughout the United Kingdom and the Republic of Ireland, often through its telephone helpline.

The United Kingdom has three distinct legal systems with a separate prison system in each: one for both England and Wales, one for Scotland, and one for Northern Ireland. As of June 2023, the United Kingdom has the highest per-capita incarceration rate in Western Europe, at 159 people per 100,000 in England and Wales; 162 people per 100,000 in Scotland; 97 people per 100,000 in Northern Ireland; and the largest prison population in Western Europe.

The demography of England has since 1801 been measured by the decennial national census, and is marked by centuries of population growth and urbanization. Due to the lack of authoritative contemporary sources, estimates of the population of England for dates prior to the first census in 1801 vary considerably. The population of England at the 2021 census was about 56,489,800.
Suicide is the second leading cause of death for people in the United States from the ages of 9 to 56.
A suicide method is any means by which a person may choose to end their life. Suicide attempts do not always result in death, and a non-fatal suicide attempt can leave the person with serious physical injuries, long-term health problems, and brain damage.
There are more than 700,000 estimated suicide deaths every year. Suicide affects every demographic, yet there are some populations that are more impacted than others. For example, among 15–29 year olds, suicide is much more prominent; this being the fourth leading cause of death within this age group.
Health in the United Kingdom refers to the overall health of the population of the United Kingdom. This includes overall trends such as life expectancy and mortality rates, mental health of the population and the suicide rate, smoking rates, alcohol consumption, prevalence of diseases within the population and obesity in the United Kingdom. Three of these – smoking rates, alcohol consumption and obesity – were above the OECD average in 2015.
Gender differences in suicide rates have been shown to be significant. There are different rates of suicides and suicidal behavior between males and females. While females more often have suicidal thoughts, males die by suicide more frequently. This discrepancy is also known as the gender paradox in suicide.
World Suicide Prevention Day (WSPD) is an awareness day always observed on 10 September every year, in order to provide worldwide commitment and action to prevent suicides, with various activities around the world since 2003. The International Association for Suicide Prevention (IASP) collaborates with the World Health Organization (WHO) and the World Federation for Mental Health (WFMH) to host World Suicide Prevention Day. In 2011 an estimated 40 countries held awareness events to mark the occasion. According to WHO's Mental Health Atlas released in 2014, no low-income country reported having a national suicide prevention strategy, while less than 10% of lower-middle income countries, and almost a third of upper-middle and high-income countries had.
Suicide is a major national public health issue in the United States. The country has one of the highest suicide rates among wealthy nations. In 2020, there were 45,799 recorded suicides, up from 42,773 in 2014, according to the CDC's National Center for Health Statistics (NCHS). On average, adjusted for age, the annual U.S. suicide rate increased 30% between 2000 and 2020, from 10.4 to 13.5 suicides per 100,000 people. In 2018, 14.2 people per 100,000 died by suicide, the highest rate recorded in more than 30 years. Due to the stigma surrounding suicide, it is suspected that suicide is generally underreported. In April 2016, the CDC released data showing that the suicide rate in the United States had hit a 30-year high, and later in June 2018, released further data showing that the rate has continued to increase and has increased in every U.S. state except Nevada since 1999. From 2000 to 2020, more than 800,000 people died by suicide in the United States, with males representing 78.7% of all suicides that happened between 2000 and 2020. In 2022, a record high 49,500 people died by suicide, while the suicide rate in 2022 reached its highest level since 1941 at 14.3 per 100,000 persons. However, this rate was surpassed in 2023, when it further increased to over 50,000 per 100,000 persons. Surging death rates from suicide, drug overdoses and alcoholism, what researchers refer to as "deaths of despair," are largely responsible for a consecutive three year decline of life expectancy in the U.S. This constitutes the first three-year drop in life expectancy in the U.S. since the years 1915–1918.
According to the Australian Bureau of Statistics, the age standardised death rate for suicide in Australia, for the year 2019, was 13.1 deaths per 100,000 people; preliminary estimates for years 2020 and 2021 are respectively 12.1 and 12.0. In 2020, 3,139 deaths were due to suicide ; in 2021, 3,144 deaths were due to suicide.
According to the latest available data, Statistics Canada estimates 4,157 suicides took place in Canada in 2017, making it the 9th leading cause of death, between Alzheimer's disease (8th) and cirrhosis and other liver diseases (10th). In 2009, there were an estimated 3,890 suicide deaths.
Suicide in Sri Lanka is a common cause of unnatural death and a long term social issue. In the past, Sri Lanka had one of the highest suicide rates in the world. For several years before 2000, the suicide rate remained at 35 to 47 per 100,000 persons. The introduction in pesticide control regulations coincided with a reduction in suicide rates in Sri Lanka. Sri Lanka Federation for Suicide Prevention is an independent organisation working on suicide prevention in Sri Lanka.
Suicide in Greenland, an autonomous country within the Kingdom of Denmark, is a significant national social issue. Greenland has the highest suicide rate in the world: reports between 1985 and 2012 showed that an average of 83 people in 100,000 died by suicide yearly.
United States military veteran suicide is an ongoing phenomenon regarding the high rate of suicide among U.S. military veterans in comparison to the general civilian public. A focus on preventing veteran suicide began in 1958 with the opening of the first suicide prevention center in the United States. During the mid-1990s, a paradigm shift in addressing veteran suicide occurred with the development of a national strategy which included several Congressional Resolutions. More advancements were made in 2007, when the Joshua Omvig Veterans Suicide Prevention Act created a comprehensive program including outreach at each Veterans Affairs Office (VA) and the implementation of a 24-hour crisis hotline. PTSD, depression, and combat-related guilt in veterans are often related to suicide as it can be difficult for veterans to transition to civilian life.
In 2017, the suicide rate in Hong Kong was around 12 deaths per 100,000 people and ranked 32 in the world standing, which was its lowest rate in four years. The suicide rate for males was nearly double that for females, as it was 16.2 deaths per 100,000 males, and 8.8 deaths per 100,000 females. Although it has decreased slightly compared to previous years, for those aged 19 or younger it has risen by 50%. The Samaritans Hong Kong charity has described the issues as worthy of attention.
Suicide in Ireland has the 17th highest rate in Europe and the 4th highest for the males aged 15–25 years old which was a main contributing factor to the improvement of suicides in Ireland.
Mental health in Australia has been through a significant shift in the last 50 years, with 20% of Australians experiencing one or more mental health episodes in their lifetimes. Australia runs on a mixed health care system, with both public and private health care. The public system includes a government run insurance scheme called Medicare, which aids mental health schemes. Each state within Australia has its own management plans for mental health treatment. However, the overarching system and spending remains the same.
