**7.6 Lessening of the productivity of city**

It is an economic theory that productivity is much more enhanced with dense development since ideas move quickly when people are in close proximity. However, when jobs move to the suburbs, people follow them. This may reduce productivity in the city, leading to social loss. In addition, authors state that sprawl leads to creating regional imbalances, such as pulling jobs and people further away from poor communities, increasing inequality. Sprawl also creates segregation of rich and poor or social isolation in general. The problem lies not to the people who have moved to the suburbs but rather to the people who have been left behind. The low-income groups are abandoned in the downtown because they cannot afford a car-based lifestyle. The role of transport technology can explain this social fragmentation. The much congested and deteriorated central towns end up being favorable places for crime and social unrest.
