Context & background literature: Environment and behaviour researchers are principally interested in the role of the physical environment on human behaviour. In the last decade there has been a rapid growth of interest in the interrelationships between the social status and environmental values. Many academic contributions have dealt with some of these topics from a theoretical perspective. In contrast, this paper therefore provides a case study analysis on the correlation between social class and the environmental values in Ibadan city, Nigeria. Two hundred structured questionnaires were administered across the social strata of (high, medium and low) social cadre. With the aid of statistical model, the research shows that social class positively influenced human-environment behaviour than the physical environment itself. And also, a correlate between social class and environmental values is examined by factor analyzing the social class variable to extract the explanatory variance amongst these inputted variables. This is aimed at stimulating empirical research interest in environment and behaviour research in developing world.
