"Growth and Future of Cities" and "The Nation's Minorities" are units eight and nine, respectively from the fourteen-units series Population Profiles. The former initiates its consideration of our urban future with two divergent points of view on population distribution. Those views are brought into perspective by an historical investigation of urban development followed by a discussion of present day trends in population distribution as evidenced in specific urban populations. The implications of such trends as population migration, new town development, and other forms of urbanization are open for consideration. "The Nation's Minorities" is a look at those groups, not accepted into the mainstream of society, through three theoretical models, the melting pot, Anglo conformity, and cultural pluralism. The groups identified and discussed are American Blacks, Puerto Ricans, Mexican Americans, Chinese and Japanese Americans, and American Indians. Maps, charts, and graphs depict demographically pertinent information about each group, such as location, education, occupation, and income level. Each of the Population Profiles concludes with a list of further references. (JH)
