This atlas is aimed at collecting, compiling and desseminating information on mental health resources in the world. It presents updated and expanded information from 192 countries with analyses of global and regional trends as well as individual country profiles. Newly included in this volume is a section on epidemiology within the profiles of all low and middle income countries. It shows that mental health resources within most countries remain inadequate despite modest improvments since 2001. Availability of mental health resources across countries and between regions remains substantially uneven, with many countries having few resources. The atlas reinforces the urgent need to enhance mental health resources within countries.
