About

This dataset provides key insights into the global prevalence and age of onset of mental health conditions, specifically anxiety and depression, across various countries and regions. Mental health is a vital aspect of well-being, influencing our ability to work and connect with others. Poor mental health affects our well-being, our ability to work, and our relationships with friends, family, and community. Despite hundreds of millions suffering yearly, treatment is often lacking, and underreporting makes accurate prevalence difficult to estimate. This data aims to support a better understanding of how, when, and why these conditions occur, the number of people affected, and how they can be effectively and safely treated.
