Addressed primarily to social scientists and administrators in developing areas, this handbook (a volume in the Technology and Society series) is designed for those not widely experienced in research design and data analysis. Many problem areas of developing nations, such as adequate housing and urban amenities, adjustment and acculturation of in-migrants, accommodation to rapid social change, effective economic organization and growth, and efficient local government, are viewed as functions of accelerating urbanization. However, developing areas are generally lacking in adequate census, administrative, and other forms of data necessary for the study and solution of these problems. Written by an international panel of experts, part one, "Social Research Data and Procedures," discusses the areal units for urban analysis, sources of data, the use of field and case studies, and appropriate research designs. Part two, "Types of Studies," is concerned with general studies of urbanization, demographic studies, the study of social organization and personal and social disorganization, and the study of urban physical plants and their administration. International bibliographies are included for all 10 chapters. A companion to this guide is: Handbook of Household Surveys: a Practical Guide for Inquiries on Levels of Living, UNESCO, New York, 1964. (DJB)
