The authors study four types of societies of bands, tribes, peaseantry and urbanites. While urging planners not to use these general categories as simplistic pigeonholes. The authors show that identifying distinctive styles of social interaction can guide church planters towards openness in a community. Charts and study data help explain class structures and social characteristics. Particular attention is paid to city dwellers since much evangelism now targets this group. For each societal setting planners receive important information about moral norms and potential social problems to expect as they carry out their ministries.
