Estimates indicate that a significant portion of the global population is affected by depressive disorders. The prevalence is measured through epidemiological studies that assess the number of individuals meeting diagnostic criteria for major depressive disorder or other forms of clinical depression within a specified timeframe. These studies offer insight into the scope of the issue worldwide.
Understanding the extent of depression is crucial for public health planning and resource allocation. Accurate prevalence data informs policy decisions related to mental health services, research funding, and prevention strategies. Historically, awareness of the widespread nature of depression has led to increased efforts to reduce stigma and improve access to treatment.
