There are over 2 million foreign workers in West Germany, representing 3.6% of the population. They come from Yugoslavia, Turkey, Italy, Greece, Spain, Portugal, Morocco, Tunisia, and other countries. 28% are women. Most of them are 18-25 yrs old, with 90% under 45 yrs. Psychosomatic illnesses and depressions are common. Accidents are 21/2 times more common among foreign workers than among their German colleagues. From 1963 to 1970, 351 foreign workers were admitted to the Stuttgart Psychiatric Clinic. Diagnoses included neurosis and psychosomatic illness (37%), schizophrenia (18%), suicide attempts (17%), affective psychoses (12%), and alcoholism and alcoholic psychoses (11%).
