It provides an overview of the major global, U.S., and California demographic changes now occurring or predicted which impact the ethnic or racial composition of communities. Key trends identified lead to a discussion of crimes motivated by race, religion, or ethnic background. Successful approaches that have been used to address this problem include police cultural awareness training and the implementation of policies, procedures, and training on 'hate' crimes motivated by race, religion, ethnic background, or sexual orientation. Two case studies summarize the transition that two southern California communities -- Monterey Park and Garden Grove -- experienced due to a heavy influx of Asians. The report concludes with strategic, implementation, and transition management plans that could be used as guides for any police agency planning for changes in the racial or ethnic composition of its community. 10 references, 8-item bibliography.
