Reading these depression statistics about how many people suffer from depression and knowing its prevalence worldwide in developed countries makes one aware and alarmed that depression is so common with such a high incidence and prevalence.
Depression is the most common mental illness affecting more than 26% of the U.S. adult population. According to Springer Link, it is estimated that by the year 2020, depression will be the second leading cause of disability throughout the world, second only to ischemic heart disease.
However, according to WHO, depression is the leading cause of disability worldwide.
You should know that depression is not a condition but a disease with changes in the chemical composition of the brain. It harms a person’s well-being more than chronic physical diseases such as asthma, angina, and diabetes. (WHO report)
According to the National Institute of Mental Health, 1998, people who have suffered from depression are four times more likely to develop a heart attack than those without a history of the illness. After the first heart attack, they are at a significantly higher risk of dying from it or developing a second heart attack.
And to make matters worse, the incidence of depression is rising at an alarming pace and more so among young children and teens. It is as if, that these unfortunate children and adults are facing increasing problems in life, which they cannot handle.
The cause of depression is not exactly known, but certain risk factors have been identified and should be read to know how prone you can be to depression. It is easy to avoid these factors and reduce your risk of going into depression. Reading the statistics below will make you do just that.
- Depression is fairly common affecting more than 300 million people of all ages worldwide.
- It is among the leading causes of disability.
- About 800 000 people die due to suicide every year. Suicide is the second leading cause of death in 15-29-year-olds. These are worldwide figures.
- Less than 25% of the depressed have access to treatment. This is either due to a lack of facilities or trained professionals or the social stigma of being a “mental patient” associated with visiting a psychiatrist.
- In some countries, the figure is less than 10%.
- More women are affected than men. The figures among women (12%) are twice that of men (6.6%).
- Women between the ages of 24 to 45 years are most commonly affected due to their inability to express anger.
- More than one million preschoolers are clinically depressed and on antidepressants. This figure is rising at an astounding rate of 23% per year.

- According to the 2014 Adult Psychiatric Morbidity Survey (APMS), the rate of people with suicidal thoughts increased from 3.8 percent in 2000 to 5.4 percent in 2014; the reason for the increase is the tripled risk of suicidal thoughts in men aged 55–64.

In Canada, it is estimated that about eight percent of adults will suffer from major depression at some time in their life.
According to the 2012 Canadian Community Health Survey (Mental Health), 11% of teenagers and young adults between the ages of 15 to 24 years showed signs of depression at some time in their life and less than half of them sought professional help for the illness.
The study also reveals that approximately 234,000 of these young people who developed depression also had suicidal thoughts at some point in time.
This is the age group with the highest incidence of depression in Canada. Suicide was the second leading cause of death among these 15 to 24-year-olds.
Another alarming fact is that suicide accounts for 24% of all deaths among 15-24 year-olds and 16% among 25-44 year old.
Again, suicidal thoughts were experienced more by young women than young men. But, the mortality rate from suicide among men is four times more than the rate among women.
Another fact that came to light was that these young people are most likely to seek support for their problems from friends and family, rather than from a professional.
According to the Canadian Medical Health Association, by the age of 40, about 50% of the Canadian population will have or have had a mental illness.
