The Death and Life of Great American Cities - Chapters 7 and 8

In chapters seven and eight, Jacobs describes the importance of having all kinds of diversity in your city. She explains that you need diversity in commerce. There should be many types of businesses. Diversity in business will lead to diversity in different areas of life in the city. She also says that businesses should serve more then one purpose. In this way they can expand their clientele and hours of business. She brings an example of down town New York. Because there is mostly office building there, the restaurants are only open during the day. Then there is no draw for people to come there at night. It is a one dimensional neighborhood and can’t function well. There needs to be diversity in neighborhoods and cities to succeed.
