This document discusses the evolution of malls in the United States and considerations for developing malls in Nigeria. It outlines 12 types of malls that have emerged in the US over 60 years. Key factors to consider include returns for investors, appropriate mall size and type based on demographics, availability of retailers, and exit strategies. Returns are the primary concern, and malls must cater to Nigerian consumer behaviors like smaller basket sizes to be successful. Developing malls in Nigeria may follow the US model but require adaptations for the local market.
