Depression Statistics for 2019

1. 16.2 million US adults have major depressive disorder.

Studies show that approximately 6.7% or 16.2 million US adults have major depressive disorder. The most common type of the illness in the country (signified by the percentage of Americans with depression) is classified as a mental disorder, which can bring symptoms that can either be long-term or short-term.

However, depression statistics in America are ever-changing, with more and more people being diagnosed each year. That said, it’s important that you keep up to date with the latest statistics.

2. 13.1% of 18-25-year-olds have a high major depressive disorder prevalence.

A study conducted in 2017 showcased that the prevalence of those with major depressive disorder was highest in adults aged 18-25. This can be due to the pressures discussed below.

The same study also found that 11.3% of those were of two or more races – the highest depression percentage in comparison to those of one race. It’s an interesting statistic when comparing age and ethnicity with depression.

3. 35% of adults with depression aren’t treated.

When looking at depression treatment statistics, the following becomes clear – only 6% are treated with medication, and 35% of adults with depression aren’t treated at all. 

They often have to wait months or years to get the help they need due to a large number of people suffering from the mental disorder and the lack of professionals within the industry. 

4. One in 13 people around the world suffers from anxiety.

Depression is arguably the most common mental disorder out there, closely followed by anxiety. As an illness that results in millions of deaths each year, it remains heavily untreated in many countries as the rates of depression increase. 

When looking at depression and anxiety statistics, one in 13 people worldwide suffers from anxiety, whereas depression affects 264 million people.

5. 4-7% of adolescents have depression, according to teenage depression stats.

Depression is one of the most prevalent mental disorders in adolescents. Teenage depression statistics have shown that 4-7% of adolescents have depression, and 20% of them have the condition once they reach adulthood. This can be due to several reasons, some of which we will discuss further below.

6. 8% of teenagers are affected by the condition for one year or more.

Similarly, other adolescent depression statistics indicate that 8% of teenagers suffer from the mental disorder for one year or more. Studies indicate that this can be due to several emotional issues, from exam stress and relationship issues to the pressure that they feel from social media. 

It can also be due to hormonal changes – an issue that is often ignored or not taken seriously in regards to mental health.

7. Depression is predicted to be the second leading cause of disability by 2020.

Depression epidemiology is frequently studied by health professionals around the world. Discovering that depression is currently the fourth leading cause of disability and predicted to be the second leading cause by 2020, the link between the condition and the impact it has on the quality of life is clear. 

However, epidemiological data ranges across countries, and the depression demographics correlate with various data regarding employment, elevated risk, current health conditions, age, etc.

8. 10-20% of new US mothers suffer from postpartum depression.

Postpartum depression statistics indicate that in the US alone, 10-20% of new mothers suffer from this condition. While exact rates are still unknown, approximately 70-80% of

women will suffer from either a mild or severe level of postpartum depression after giving birth. 

9. One in seven US women experiences postpartum depression one year after giving birth.

According to statistics, one in seven US women (600,000 in total) are diagnosed with postpartum depression each year, within 12 months of giving birth. However, this is only taking into account babies that have been delivered safely. Those suffering from stillbirths or miscarriages can also be affected.

10. 65% of new mothers in Asian countries suffer from postpartum depression.

Whilst looking at depression rates in terms of demographics, it was found that postpartum affects approximately 65% of new mothers in Asian countries. Although it’s unknown as to why this statistic is so large, there are several possible causes – from social pressures to pressures within the home.

11. 50% of those who suffer from depression commit suicide. 

According to depression and suicide statistics, over 50% of depression patients die by their own hand. The rates of depression rise when we take into consideration those with an alcohol addiction who have depression. In this case, the number goes as high as 75%.

12. 13-66% of teenagers have depression due to social media platforms.

Over the last few years, several studies have looked at the correlation between social media and depression. Uncovering that 13-66% of teenagers have depression due to the usage of platforms such as Facebook, the figures are difficult to ignore. 

Other social media and depression statistics revealed that in 2017, over 500,000 of 8th to 12th-grade young adults had rapidly increasing levels of depression – increasing by 33% between 2010 and 2015.

13. Between 2010-2015, the suicide rate of young adolescent girls increased by 65%.

The same study also indicated that suicide rates of young adolescent girls also increased by 65% from 2010 to 2015. Again, this is commonly linked with pressures from social media, pressures at home (whether that be from exam stress or by parents), or from broken relationships.

14. Depression in college students statistics for 2017 indicate that 40% of college students suffer from depression.

According to a survey carried out by the American College Health Association, 40% of college students faced symptoms of depression throughout the year, whilst 61% of students noticed signs of anxiety. With the survey questioning 63,000 students throughout 92 schools, these statistics are extremely worrying.

15. Depression in elderly statistics show that 1-5% of the elderly suffer from the condition.

When looking at depression in older adult statistics, it’s clear that there is a high prevalence of the illness among this generation. According to CDC depression statistics (Center for Disease Control and Prevention), the condition affects approximately 1-5% of the elderly population, 13.5% of which require healthcare at home. 

16. According to 2018 depression statistics, as family income increases, the prevalence of depression decreases.

A survey conducted by the CDC in 2018 found that as the level of income increases, the chances of depression amongst adults decreases. This might be due to several reasons – from better access to mental health services to reduced stress due to the level of income.

17. Sexual and gender minority youth are three times more likely to suffer from depression.

According to a 2012 survey, sexual and gender minority youth are three times more likely to exhibit signs of depression. LGBT depression statistics found that one in five of its members attempted suicide due to the condition. The same survey identified that LGBTQI+ youth are more likely to face alcohol or drug addiction.

18. Seasonal affective disorder (SAD) affects over 10 million Americans.

Studies have shown the correlation between holiday depression statistics and SAD. Affecting 10 million Americans and millions globally, its causes are Christmas or another holiday, lack of social interaction, and even the weather. The main symptoms of holiday depression are social withdrawal, an increased need for sleep, the feeling of unworthiness, and weight gain.

19. Male vs female depression statistics indicate that 8.7% of females suffer from the condition, compared to 5.3% of males.

Major depressive disorder statistics show that 8.7 % of adult females and 5.3% of adult men suffer from the condition. This can be due to biological factors such as pregnancy and hormones, as well as personal life circumstances.

20. 2% of school-aged children have depression.

With this number on the rise, the factors that cause these childhood depression statistics are still relatively unclear. However, many health professionals have indicated that childhood depression can be due to issues such as bullying, physical, and emotional abuse.

21. 36.4% of college students have depression. 

By looking at depression in college students statistics, the mental condition is a growing concern because it affects approximately 36.4% of college students, according to a 2013 study. 

As teen depression statistics grow, studies have signified that it’s the number one reason why so many college students drop out. It can also lead to suicide or major depressive disorder if left untreated.

It’s clear that the rate of depression in the US and beyond will continue to rise in the coming years. Affecting people of all ages, socio-economic background, and other demographics, it’s a condition that will continue to be at the forefront of people’s minds as the years go on. 

Ranging from mild to severe cases, clinical depression statistics will adapt as time goes on due to numerous factors – some of which were discussed above.

A mental health condition can affect anyone at any time. These statistics indicate the need for improved mental health care and signify the importance of seeking help. 

However, this can be easier said than done in some countries. For example, those living in wealthy countries such as the UK or America might find it easier to access such services, whereas those from lower-income countries may struggle to find those resources or pay for them.

In any case, you need accurate depression facts and stats to better understand the topic, and we hope that the above-discussed depression statistics would help you to become more aware of this global issue.


How many people in the world have depression? 

According to the World Health Organization, approximately 264 million people suffer from depression worldwide.

Although these depression statistics worldwide are growing every year, this huge number is one that health professionals and others should take note of from the get-go. From the data above, it’s clear that there are many causes of depression, from bullying that affects childhood depression to low income and stress at work, which tends to affect older adults. 

Which race has the highest rate of depression? 

Over the years, several studies have explored the prevalence and correlation of race with the condition – collecting numerous statistics on depression throughout the process. Although minority populations are “less likely to suffer from acute episodes of MDD than Caucasians, they are more likely to suffer from prolonged, chronic, and severely debilitating depression.” This can be due to the lack of healthcare or the feeling that they won’t be listened to if they do try and seek help.

A similar study found that the “overall lifetime prevalence of major depressive disorder among Caucasians was 17.9% as opposed to African Americans, whose prevalence estimate was only 10.4%. The difference between African Americans and Caucasians lies in the fact that the chronicity of disease was higher for African Americans (56%) than it was for Caucasian patients (38.6%).”

These statistics showcase that although Caucasians do make up a large percentage of the global rate of depression, it’s those from a minority background or those with a low income that are affected with more severe levels of the mental condition.

What age group has the highest rate of depression? 

According to a recent article, after carrying out a study between 2009 and 2012, the highest rate of depression (12.3%) was found in women aged between 40-59. The Centers for Disease Control and Prevention reports that this percentage could be due to an array of factors, such as pressures at home, the menopause, stress regarding income, etc. Notably, it was also found that women in that age range were less likely to seek treatment, as they were embarrassed about their mental health. 

This stigma is continuing to be prevalent globally, despite the call for treatment and numerous resources detailing this data.

What percentage of Americans are depressed?

Around 6.7% of American adults are depressed, whether that be Clinical Depression, Major Depressive Disorder, or another type of depression. Although this number of 16.2 million people doesn’t necessarily seem a lot in the context of the entire US population (327.2 million), it’s still a significant number. What’s worse, it is on the rise and, therefore, shouldn’t be taken with a pinch of salt. 

With millions of adolescents and school-aged children also being affected, whether due to bullying or the impact of social media, the overall number of Americans that are facing this mental health condition and the overall depression statistics will undoubtedly continue to grow as time goes on.
