More money is spent on Halloween pet costumes and takeaway coffee in developed countries than on mental health in developing countries, a new report has found, with the amount accounting for less than 1 percent of all aid funding.

Although mental health problems affect 1 in 4 people globally, the Overseas Development Institute (ODI) report found that only $133.57 million is spent per year on mental health services across 148 developing countries.

This is less than the amount spent on takeaway coffee in Britain in a week and less than Americans spent on Halloween pet costumes in 2015.
