Economic opportunity divides urban and rural dwellers. Traditionally and historically, there are greater economic opportunities in urban areas. In urban areas, more people are concentrated in a smaller space, resulting in a need for a greater number of shops where these people can buy the goods they require. There is also a greater need for adequate transport systems. Wide enough roads need to be built to accommodate a greater number of cars and busses. This creates jobs for people as the roads need to be built and maintained.
