The distribution of attempted suicide among Commonwealth immigrants has been investigated in Birmingham. Four-year data concerning 119 (43 male, 76 female) admissions to hospitals there have been used. The crude rate of attempted suicide (94 per 100,000 per annum) is lower than that for the native population. All the patients were younger than 44, and repeated suicide attempts were rarely seen and drug or alcohol abuse were found to be less prevalent than among admissions of British origin. The data indicate that attempted suicide among immigrants in Birmingham is benign in comparison with that among the natives there.
