Research clearly indicates that ethnic groups differsignificantly on levels of mental and physical health, antisocialbehavior, and educational attainment. This book explains thesevariations among ethnic groups with respect to their psychologicaland social functioning and tests competing hypotheses about themechanisms that might cause the functioning to be better, worse, ordifferent in pattern from other groups. Attention is paid toeducational attainments, antisocial behavior, schizophrenia andsuicide, and to the complex and changing patterns of ethnicidentity. The book also focuses on evidence on risk and protectivefactors that is used systematically to ask whether such factorsmight account for the differences in both migration histories andethnic mixture. It concludes with a discussion of the multiplemeanings of ethnicity, the major variations among ethnic groups,and the policy implications of the findings discussed in thebook.
