International organizations like the United Nations and the World Health Organization are beginning to prioritize mental health as a serious public health crisis, yet it remains starkly under-funded.

However, as depicted in the above graph, financial efforts to improve health outcomes for those with depression, anxiety, or other mental illnesses fall well short of meeting needs in low, middle, and high-income countries.
