Data deriving from the Mental Health Enquiry were obtained from the Department of Health and Social Security (DHSS) for all 186,000 admissions in England in 1981 to test the 'ethnic density hypothesis'. This hypothesis has been used to explain variations in rates of mental illness between ethnic groups in other countries, and suggests that there is an inverse relationship between the size of ethnic groups and their admission rates. The data analysed in the present paper for the main foreign-born immigrant groups to England not only failed to support the ethnic-density hypothesis, but in some cases, showed a significant positive relationship between group size and admission rates. Some possible reasons for these findings are explored.
从心理健康调查中获取的数据来自卫生与社会保障部（DHSS），涵盖了1981年英格兰所有18.6万例住院病例，以检验“种族密度假说”。该假说已被用于解释其他国家不同种族间精神疾病发病率的差异，表明种族群体规模与其住院率之间存在负相关关系。本文所分析的主要外国出生移民群体到英格兰的数据不仅未能支持种族密度假说，而且在某些情况下，还显示出群体规模与住院率之间存在显著的正相关关系。文中探讨了这些发现的一些可能原因。
