The purpose of this study was to explore the way of life of ordinary urban residents in cities of varying sizes and types in various parts of Nigeria, especially in regard to social networks and activities, occupational and migration careers, and attitudes toward urban life, education and members of ethnic groups. Variables Dr Peil's study was designed as a comparative study of the daily life of people living in cities in various parts of Nigeria, these cities differing in size and composition. Data were collected by oral interviewing, supplemented by observation, mapping, recording of schools, churches, health facilities, government services, craftsmen, etc. Only the interviewing data (from cities Ajegunle, Kikuri, Abeokuta and Aba) have been supplied to the Archive. To quote from Dr Peil's report: 'Investigation of social networks provides a framework for testing hypotheses about social change and modernity, adjustment to urban life and the social effects of various types of housing and various kinds of employment. Identical studies of several cities permit analysis of the effects of city size, heterogeneity and social structure on the lives of the inhabitants. . . . The 'quality of life' measured in this study is concerned with items which can be easily reported by individuals rather than with official statistics. . . . It was also hoped that this study would be useful to urban planners, who generally have very little information on what the average family makes of its life in town. What are their expectations and their aspirations? What amenities do they most appreciate and most miss? How much urban experience have they had and how long can they be expected to stay, especially in the face of unemployment? How much unemployment is there and how are the unemployed supported?. . .' Hence, there is detailed demographic information for a general picture of the population of the four cities. The housing section collects details on household composition, overcrowding, landlords and inter-ethnic mixing. Marriage and kinship information indicates the numbers and location of wives and children, attitudes and practices in educating children, contacts with relatives in town and at home, and plans for returning home. A social life section deals with membership in associations, and contacts with co-tenants, workmates and friends. Information is also collected on how urban dwellers handle problems, and there is detailed occupational and migration career data.
