 In a small church the minister typically knows everyone, and the congregation is “one big family.” It is not easy to grow beyond 150 members, however, because that requires (besides a bigger building) augmenting the minister with paid staff, systematically recruiting and training volunteers, and dealing with increased numbers and diversity by developing specialized groups and programs.Educators are advocating subdividing large schools into smaller units so that staff can know all the students and there will be more feeling of belonging, support and continuity.As settlements grow in population they increase in density, complexity, diversity, and administrative apparatus.
