Depression Facts and Stats: Prevalence

Depression Statistics

1. Millions of adults will experience depression at some point in their lives.

(Verywell Mind)

After all, there are many different types of depression, just as there are several ways it can impact someone’s life. Because the symptoms and the degree of the health disorder can vary, it’s important that people seek out a medical professional for a proper diagnosis.

2. Bipolar disorder affects around 2.8% of the US population.

(National Institute of Mental Health)

Bipolar disorder, or manic depression, is another form of depression that affects millions of Americans every year. The “mood episodes” brought on by this disorder include unusual swings in one’s energy level, emotional state, and overall activity. According to bipolar disorder statistics from 2018, this disorder is experienced equally by both men and women. Most importantly, 83% of these cases are considered severe.

3. 50% of people dealing with depression also experience an anxiety disorder.

(Verywell Mind)

What’s worse, depression can also be accompanied by severe anxiety disorder. The associated mood changes seriously impact daily functions. Because there’s so much correlation between most depression and anxiety statistics, it’s important to know the differences between the two disorders. An anxiety disorder can induce feelings of nervousness or panic, a rapid heartbeat, shortness of breath, or even dizziness and nausea.

4. About 25% of patients admitted to hospitals due to depression are actually suffering from psychotic depression.

(Healthline)

Depression comes in several different forms. Depression statistics over time have shown that on a worldwide scale, 1 in 13 people will experience a psychotic depressive episode before age 75. Chronic depression levels vary in severity—as do most types of depression—and sometimes may lead to hospitalization. In the case of psychotic depression, it’s a much more severe case of depression or bipolar disorder and can involve hallucinations, delusion, or paranoia.

5. About 3.8% of the world suffers from this mental health disorder.

(The World Health Organization)

What percent of the population has depression? Depression impacts almost 4% of the world population and a wide range of demographics across age, gender, ethnicity, and location. Over the past years, various stats have been laid out in order to depict the prevalence of this health disorder. The World Health Organization’s reports show that over 300 million people in the world are suffering from depression.

6. Patients of other medical conditions experience depression.

(The Depression and Bipolar Support Alliance)

According to the National Institute of Mental Health and depression statistics on a worldwide scale, 25% of cancer patients have experienced depression, 10%–27% of stroke patients deal with depression, and even 33% heart attack survivors experience depression. People living with chronic pain are also highly likely to be depressed. Friends, family, and medical professionals must be on the alert for depression symptoms in patients diagnosed with these types of severe medical conditions.

7. Anxiety disorders are the most common mental disorders when compared to depression.

(Verywell Mind)

Around the world, depression affects millions of people. However, anxiety statistics worldwide indicate that anxiety disorders with a specific phobia, major depressive disorder, or social phobia are the most common in the world.

8. Depression is more likely to lead to impairment in adults.

(Verywell Mind)

This type of impairment is highly pervasive, impeding elements of a patient’s social, work, and educational life. In fact, about 10.3 million adults in the United States suffered an episode that resulted in severe impairment, according to depression statistics, in 2018.

Depression Demographics

9. Women are more likely to experience depression than men.

(Healthline)

Many people believe that men suffer from this health disorder more often than women. As a matter of fact, research carried out by the WHO shows that more women are affected by depression than men. Additionally, women are twice as likely to have had an MDE (major depressive episode). Mental health statistics also indicate that about 10%–15% of women in the United States have a depressive episode within three months of childbirth.

10. Young adults aged 18–22 are the most likely age group to suffer from depression.

(Healthline)

A good number of people around the globe believe adults are the only demographic dealing with problems of depression. In actual fact, major depressive episodes are more common in young adults from age 18 to 22. And the depression in college students statistics point to this fact too.

11. 8% of children suffer from an anxiety disorder.

(Anxiety and Depression Association of America)

As we already saw, depression can often accompany anxiety disorders. In fact, millions of children and teenagers develop symptoms of anxiety before age 21.

12. 1 in every 8 middle-aged women suffers from depression.

(Livescience)

Reports and case studies found among CDC depression statistics from 2018 show that women who fall within the age range of 40–59 have a 12.3% rate of experiencing depression. This particular demographic has the highest rate of depression overall.

13. 19.7% of people in the UK aged 16 and over showed symptoms of anxiety or depression.

(Mental Health Foundation)

Depression is regarded as one of the top health disorders that affect people worldwide. In keeping with the previous statistics, the percentage was higher among females than males. It’s worth noting that this number is lower than similar depression statistics in America.

14. About 15% of people living in poverty have depression.

(Livescience)

Conversely, people who live above the federal poverty level have a depression rate of 6.2%. This means that those who live in poverty are twice as likely to be persistently depressed.

15. Over 2.8 million adolescents have depression.

(ADAA)

Just as adults are vulnerable to depression, children and teens also suffer from this health disorder. Taking a look at the WHO’s research and other related adolescent depression statistics, we can see that 2%–3% of kids between the ages of 6 and 12 and 6%–8% of teens may have had severe depression.

16. Approximately 10%–15% of adult mothers experience postpartum depression after childbirth.

(NCBI)

Usually, this lasts for a period of about a few months to a year, though in some cases it can last for a few years. They may experience anywhere from mild to severe symptoms of depression. According to reports based on verified postpartum depression statistics, only 1 in 5 women suffering from the disorder will speak to a healthcare professional about their symptoms.

17. 50% of women who are diagnosed with postpartum depression started to notice symptoms during their pregnancy.

(Verywell Mind)

While it’s common for women to suffer from some symptoms like depression after giving birth, like loneliness or stress, postpartum depression can be more severe and problematic. What people often don’t realize is that several reports and studies, many based on the mental health statistics from 2018, show these symptoms manifesting earlier than we expect.

18. Half of all women diagnosed with postpartum depression had never had an episode of depression before.

(Verywell Mind)

This means that about 50% of the women experiencing postpartum depression may not even recognize their symptoms. In fact, only about 15% of women with postpartum depression actually end up receiving treatment.

19. Around 6.7% of American adults have experienced depression.

(Healthline)

This means that 16.2 million adults have had at least one major encounter in a given year. This, of course, goes a long way toward showing how pervasive the health disorder is. That’s a high number of people going through their usual workdays and the ongoing stresses of adult life while also battling depression. Now we have a clear answer to the question: how many Americans are depressed?

Treatment of Depression

Depression Statistics

20. Approximately 35% of adults who’ve had a major depressive episode did not receive treatment.

(National Institute of Mental Health)

The alarming number of adults who haven’t received treatment for their depression may be due to a few simple factors. For example, they may not want to report their health disorder to healthcare professionals or they may be unaware of their condition. However, US depression statistics also show that 65% have received combined care by a medical professional and/or medication treatment.

21. Severe depression left untreated can lead to serious health conditions.

(Healthline)

Many people around the world overlook this health disorder. But in actual fact, it can be highly chronic and, hence, lead to additional disorders if improperly treated. According to the World Health Organization, therapy, medication, diet, and exercise can be effective treatments for depression.

22. In many countries, fewer than 10% of the people who have depression receive treatment.

(National Institute of Mental Health)

Depression facts like these can be the result of many things, including inaccurate medical assessments or a lack of trained healthcare providers.

23. Depression can be treated pharmacologically and psychologically.

(The WHO)

According to the World Health Organization, the psychological and pharmacological treatments have been proven efficient and effective. Today, patients of depression who report their health disorder may eventually eradicate depression from their lives. And yet, mental illness statistics worldwide from 2018 include reports showing that almost 75% of people with mental disorders remain untreated even with the availability of professional care.

Depression and Its Impact on the World

25. Depression can lead to suicide.

(The WHO)

Around 800,000 people die due to suicide every year. On top of that, according to the World Health Organization’s depression and suicide statistics, depression has been shown to lead to suicide. Even more concerning, suicide is the second leading cause of death in youngsters and young adults aged 15–29.

26. Every day, approximately 110 Americans take their own life, and about 3,500 attempt to do so.

(HDRF)

Depression is the main reason why someone dies of suicide in the US every 13 minutes—over 41,000 people a year.

27. About 1 in 5 teens in the United States suffers from a mental disorder.

(Livescience)

The severity may be enough to cause impairment or even affect daily functions at some point in their lives. This is well backed up by the recent teenage depression statistics from 2018 put forward by the World Health Organization.

28. Depression contributes to the overall global burden of disease.

(The WHO)

Patients who experience other forms of health disorders and diseases are already going through a hard time. While some diseases lead to a likelihood of developing depression, the opposite can also be true—like in the case of cardiovascular disease.

29. The total economic burden brought about by depression is $210.5 billion.

(Verywell Mind)

As per anxiety statistics in 2018, depression and anxiety are globally regarded as a burden to the economy. For this reason, a whopping sum of $210.5 billion is estimated to be their total economic burden.

(Verywell Mind)

Reports have shown that about 50% of economic costs are attributed to the work absences, disability, and decreased productivity of workers suffering from depression.

31. Generalized anxiety disorder affects about 3% of adults in the United States.

(ADAA)

Commonly known as GAD, generalized anxiety disorder affects over 6.8 million adults in the US.

Studies have shown that social media may actually increase feelings of depression and loneliness.

32. 12 billion working days will be lost each year due to mental illness by 2030.

(The Guardian)

Depression and mental illness can greatly impede the future of our economy. As a matter of fact, several million years of work could be lost to depression. According to the World Health Organization and their data on the impact of depression by 2030, this can go a long way toward injuring the economy. These numbers show notable losses to businesses, companies, and even the government.

Other Important Facts About Depression

Depression Statistics

33. Depression can shorten the lives of cancer patients.

(Factretriever)

25% of cancer patients experience depression due to their medical condition, as we saw in the previously mentioned depression statistics from 2017. However, according to research, depression can also shorten the lives of these patients. For this reason, many cancer patients are made to go through various treatments for this health disorder.

34. 2% of children with depression are treated with medication alone.

(Verywell Mind)

Although there are numerous ways to treat depression, one of the easiest and fastest is to use medication. The current depression rates over time graph also shows that around 19% of children see a healthcare professional for their depression. However, 60% receive no treatment at all.

35. Children with both asthma and depression experience a higher level of asthma in their lives on average.

(Factretriever)

Unlike children without depression but with asthma, children with both asthma and depression experience a more chronic level of asthma. This can be very challenging for kids. But with the many treatments and professional care readily available, this can become manageable.

36. Middle-aged men are more likely to experience depression.

37. 15% of the world’s adult population will experience depression.

(Verywell Mind)

While this may not include the majority of the world population, this percentage is more than high enough for people to take notice. Considering the health-based consequences of depression, not to mention the way it impacts the quality of life, it’s worth educating people on the symptoms and treatment options.

38. Depression will become the second highest medical cause of disability by the year 2030.

(Factretriever)

This is according to the World Health Organization’s research on the most depressed countries from 2018. This is an improvement from depression being the leading cause of disability. It may soon place second to HIV/AIDS in this case.

39. 1 in 3 HIV patients experience depression.

(DBSA)

An unusually high percentage of patients with HIV and AIDS get diagnosed with depression likely owing to the fact that the condition is incurable.

40. India is the most depressed country in the world.

(Indiatoday)

The country made the top of the list among the world’s most depressed countries with 6.5% of its population suffering from depression. This comes close to answering the question: which race has the highest rate of depression? This is according to the report from the World Health Organization conducted for the NCMH (National Care of Medical Health). The country’s large population is also a contributing factor to this data.

Final Thoughts

A good number of the above facts cover more than just depression. That’s because this health disorder’s overall impact is so pervasive—it even influences the world’s economy. Looking through the top depression stats, it’s clear we need to continue giving depression the attention it needs so that everyone can get the right treatment.

Always remember that none of this is the patient’s fault—depression can be brought about by an imbalance in the brain’s chemistry, genetics, or traumatic life events. It’s crucial to report cases to a medical professional before the health disorder can worsen or even start to impact quality of life. With the above depression statistics in mind, our experts from MedAlertHelp hope you’re better prepared to convey your knowledge and help everyone work together in the fight against depression.
