Depression is a disorder of mental health characterized by feelings of worry, sadness, hopelessness, and numerous other physical and psychological symptoms. Depression in America, Europe, and the UK is on the rise for the last couple of decades. Depression statistics in 2022 are the worse since the inception of time. Depression can afflict individuals of various genders, ages, and socioeconomic classes. Although depression and anxiety statistics vary slightly depending on the source, here are a few global depression statistics from trusted statistical sources to begin with:

  • Approximately 280 million individuals worldwide suffer from depression.
  • It is believed that approximately 5% of adults worldwide suffer from depression.
  • Nineteen percent of individuals reported having been diagnosed with depression, including postpartum depression, at some point in their lives. This is the most prevalent diagnosis documented.
  • More women than men suffer from depression.
  • Depression can lead to self-harm and suicidal ideation.
  • There are effective treatments for mild, moderate, and severe depression.
  • Depression is the most significant global cause of disability and a substantial contributor to the worldwide disease load.

Depression has significant and varied effects, despite the seeming simplicity of its definition. Here are some interesting facts regarding depression that may not be widely known.

  • Depression has numerous causes. A person’s risk of depression increases if they have recently experienced a stressful life event, if they had been depressed in the past, or if a close relative has been depressed. Occasionally, depression develops for no apparent reason.
  • Genetics offers some of the answers, but not all. The genetic tendency to depression is becoming increasingly recognized, which may explain why some individuals get depression while others do not. A familial history of depression is significant, but it is not the only cause. As per a study published in 2018 in the journal Frontiers in Psychiatry, the heritability rate (the proportion of a trait that may be attributed to genes) of depression is only approximately 37%.
  • Depression has physical effects. As per the NIMH, gastrointestinal issues, headaches, pains, and general aches without a specific physical reason are all indicators of depression.
  • Depression may be a “gut instinct.” A study that was published in August 2020 in the journal Cureus discovered a substantial relationship between mental health and gut health, indicating that depression is highly linked to gut imbalance. Although additional research is required, a diet rich in prebiotics and probiotics may be beneficial in depression management.
  • Brains affected by depression may vary in structure. A study published in December 2019 in the journal Translational Psychiatry assessed research investigating the use of MRI scans to treat and diagnose the major depressive disorder, and found that imaging tests like magnetic resonance imaging (MRI) scans can detect changes in the brains of some individuals with major depressive disorder. (However, the article also mentions that major depression is a biochemically complex disorder that results in different brain changes in some individuals and that MRI scans alone aren’t useful in the identification of major depressive disorder; consequently, the researchers emphasize the significance of modern imaging techniques and methods of analyzing that data to help diagnose depression.)
  • Depression is associated with various health issues. People suffering from depression are also at increased risk for autoimmune or chronic inflammatory diseases, like diabetes, arthritis, heart disease, and irritable bowel syndrome. As per a study released in July 2019 in the journal Frontiers in Immunology, it is uncertain if depression induces inflammation or vice versa.
  • Depressed individuals may not appear depressed. Depression is a veiled disease. Some people may appear cheerful, yet they struggle with depressive symptoms on the inside.
  • Exercise can help control depression. Exercise increases mood state. Physical activity stimulates natural substances in the body that might improve mood. Most days, try to get at least 30 minutes of exercise. Typically, we advise depressed individuals to exercise, adopt a nutritious diet, and adhere to a normal sleep schedule. A study published in the American Journal of Psychiatry in October 2017 indicated that just one hour of regular exercise per week was linked with a 12% reduction in the risk of depression.
  • It is usual to require the use of many antidepressants. Many depressed individuals do not find relief from the first antidepressant they take. This is predicted since, for unexplained reasons, some people respond favorably to different drugs, and some do not respond favorably to any of the currently available medications. Individuals may need to take multiple antidepressants before finding one that works effectively.
  • Oftentimes, therapy is also needed. Therapy and lifestyle adjustments are regarded as first-line treatments for mild to moderate depression; however, a combination of medication and therapy is frequently effective for moderate to severe depression. Sometimes antidepressants are used first to reduce depression sufficiently for treatment to be beneficial. Effective treatment for depression also requires cognitive behavioral therapy, psychotherapy, or other therapeutic methods like Transcranial magnetic stimulation.
  • Depression is frequently accompanied by anxiety. Many individuals with one mental health condition, like depression, may also suffer from another, like attention deficit hyperactivity disorder or anxiety. Anxiety can be as devastating as depression, but folks may not realize they have anxiety because they have lived with it for so long. Women are particularly susceptible to developing anxiety problems.
  • Depression has a major impact on the global population. The World Health Organization reported in February 2017 that depression is the largest cause of disability worldwide, affecting over 300 million people worldwide. Between 2005 and 2015, the number of individuals battling depression increased by 18%, with the majority being young people, older people, and women.

Although the depression rate by the state might vary, the following are some of the stats and percent calculations of the rate of depression in the US as a whole:

  • An estimated 21 million American adults experienced at least one major depressive episode. This constituted 8.4 percent of all American adults.
  • 63.8 percent of adults and 70.77 percent of adolescents with major depressive episodes were severely impaired. (NIMH)
  • The incidence of major depressive episodes was significantly greater among adult females (10.5 percent) than among adult males (6.2 percent).
  • Depression is about twice as prevalent among women as it is among men. (Centers for Disease Control)
  • The prevalence of major depressive episodes was highest among adults (11.3 percent) and adolescents (16.9 percent) who reported two or more races. (NIMH)
  • The peak incidence of adults having a major depressive episode was among those aged 18 to 25.
  • The incidence of major depressive episodes was highest (15.9 percent) among individuals who reported having two or more races.
  • In 2020, a projected 66 percent of U.S. people aged 18 or older suffering from a major depressive episode will have received therapy during the previous year.
  • Seventy-one percent of patients diagnosed with a major depressive episode with significant impairment got treatment within the last year.
  • In the United States, a projected 4.1 million adolescents aged 12 to 17 experienced at least one major depressive episode. This constituted 17 percent of the American population aged 12 to 17 at the time.
  • The occurrence of major depressive episodes was greater among female adolescents (25.2 percent) than among male adolescents (9.2 percent).
  • The prevalence of major depressive disorder was highest (29.9 percent) among teenagers who reported more than two races.
  • Between July 27 and August 8, 2022, approximately 22% of U.S. adults exhibited depression disorder symptoms. In the past 2 weeks, around 23% of female participants in the United States experienced signs of depression illness, compared to 21% of male respondents. These depression statistics for the year 2022 reveal the proportion of U.S. respondents older than 18 years old.

In 2019, 7.2 percent of EU people reported suffering from chronic depression, which is a little increase from 2014 (+0.3 percentage points).

In 2019, Portugal (12.2 percent) had the greatest prevalence of chronic depression among EU nations, followed by Sweden (11.7 percent), Germany, and Croatia (11.6 percent).

In contrast, the lowest rates of chronic depression were recorded in Romania (1.0 percent), Bulgaria (2.7 percent), and Malta (3.5 percent).

In the spring of 2020, it was predicted that 53% of European individuals between the ages of 18 and 34 were at risk of developing depression; by the spring of 2021, this percentage had risen to 64%. Comparing spring 2021 to spring 2020, there was a considerable increase in the proportion of people at risk for depression across all age categories. Unfortunately, depression statistics in 2023 are expected to rise even further.
