can someone explain the most appropriate statistical test to run on this question?

Government researchers are concerned about high rates of suicide among young men in in Australia. They want to know what factors are associated with an increased risk of suicide so that they can develop targeted prevention interventions. They collect data from a random sample of 2000 young Australian men (aged 18-35), including a measure of their level of suicidality, and several variables they hypothesise may be associated with suicidality including income, number of close friends, and alcohol consumption (drinks per month).
