Core tip: This review provides evidence for an association between economic recession and suicide at the ecological level. There is also evidence that the most recent recession is associated with an increase in suicide rates in high income countries such as Europe and North America. Methodological issues somewhat limit the comparability of some of the studies. High income countries were overrepresented in included studies, meaning that future studies in this area should focus their analyses on low and middle income countries wherever possible. More individual level analyses are also required in order to identify causal associations between economic recession and suicide.
