Whilst the number of people currently experiencing homelessness cannot be precisely estimated due to varying definitions across countries and cultures, the link between homelessness and mental health disorders is undeniable. Both are strongly affected by social and economic determinants such
as poverty, migration, unemployment, access to healthcare, and urbanization and, as a result, providing optimal care in the community requires understanding of the cultural context.

Part of the Oxford Cultural Psychiatry series, this unique resource provides an overview of the connection between homelessness and mental health around the globe. Over 27 chapters it offers up-to-date research and policy evidence with an emphasis on developing models of social care and
rehabilitation at a local level that enable easy access to mental health services. Written and edited by experts drawn from different cultural and geographical perspectives, this unique resource covers key topics such as COVID-19, dental issues, and chronic pain, the experiences of specific
vulnerable groups, as well as case studies from specific countries.
