Much of the research on suicidal behavior in Muslim countries has been simple descriptive studies of samples of completed and attempted suicides. Despite this, and despite the possible under-reporting of suicidal behavior in countries where such behavior is illegal, suicide rates do appear to be lower in Muslims than in those of other religions, even in countries which have populations belonging to several religious groups. Rates of attempted suicide, on the other hand, do not appear to be lower in Muslims as compared to non-Muslims. Research into this topic has been quite poor, failing to take into account the ethnic background and the Islamic sect to which the suicidal subjects belonged. Reasons for the low rate of completed suicide in Muslims are reviewed, including differences in values and socio-economic status.
