TRENDS IN THE METHODS USED FOR SUICIDE IN NORTHERN-IRELAND

As domestic gas was made less toxic in Northern Ireland during the period 1960-1988, it was used less often for suicide. During the same period, as car ownership increased, the use of car exhaust for suicide increased in popularity without there being a corresponding decrease in the use of other methods. Part of the temporal variation in suicide rates in Northern Ireland may be accounted for by the relative availability of lethal methods for suicide.
