The Death and Life of Great American Cities
The Conditions for City Diversity analysis

Part two of Death and Life explains several conditions for city diversity based on the observations of different American cities and discusses in depth the four factors that Jacobs believe are critical for the development of a city. The basis for generating diversity lies in these conditions, and cannot be secludedly achieved by planning and designing. This part lays out the foundation and is the basis for the rest of the book. It shows urban planning and many possible remedies for creating equal diversity, and studies why these are not applied and the effects of it not being so.
These four conditions state that internal parts must provide …show more content…

The need of short blocks is described with the example of Manhattan, where the use of long blocks segregate walking citizens and isolate people socially as well as economically. She argues that frequent streets and short blocks are more valuable since they provide cross-use of the streets. Most shops are dependant on people passing by each day, and short blocks could control the passings and create a diverse and balanced income for them.

The mixture of buildings of different conditions are necessary to public life because it otherwise would be neither interesting nor fascinating. But the main reasons are because they ensure low rent yields, encouraging the growth of small enterprises. Large swatches of new construction would only prevent income since not many would afford it, and the demand for it would not be as large as it would need to be.

Equal diversity created by a dense concentration of people is a necessity, since the other factors will have no effect if this condition is not
