  • Large cities, people (low- and moderate-income) live in the inner city because majority of them have no place to go.
  • NYC- 3 million crowded into apartment (5-story 75-100 yrs-old)- unsanitary, worn out and infested by rats and cockroaches., but,
  • The sense of neighborhood, social structure, and continuity persists.
  • Drug abuse, crime, vandalism and other social problems, relationship between communities and law enforcement officers very tense.

More Americansingle

and DINK people show the interest

1. Stop the deterioration of the urban core-new residential construction to lure the suburban residents- failed.

2. “Gentrification”- the rehabilitation of deteriorated and abandoned inner-city housing with favorable locations relative to the CBD and central city places of employment

High-cost of housing causing more homeless

does commercialization help
Does commercialization help?
  • New waterfront theme built in NY, Baltimore, only attracts more tourist and generate business, but couldn’t keep the permanent residents

  • It was the localized reactions to sweeping economic, political, and ethnic changes unfolding at regional and even global scales.
  • Between 1978 and 1982, over 70,000 job lost in south-central LA. In 1990, Latinos and African American, and Korean comprise most of the residents in this area. They all tried to survive in this jobless area.
  • James Johnson found that the riots were rooted in the growing despair and frustration of different ethnic groups competing for a decreasing number of jobs in an environment of declining housing conditions and scare public resources.
suburban city
Suburban City
  • “Country life with city comfort” and the advance of automobile made the suburban life possible.
  • Suburbs plan their zones in response to choice and demand which express the idealized living patterns more accurately than any other urban zone.
  • J.H. Johnson- “Suburban life and landscape are in much closer adjustment”.

  • Economic vitality helped mitigate its social problems.
  • The central city serves as location for gov’t, hotels, entertainment, sports and ceremonies. Companies established corporate headquarters in “edge cities” on Atlanta’s urban perimeter.

the canadian city toronto 80 of ontario pop live in urban areas
The Canadian City - Toronto (80% of Ontario pop live in urban areas)
  • Canada’s major cities suffer much less from the problems plaguing American cities.
  • For example, Toronto is much less dispersed than an American Cities with same population, more middle and high income residents in city and result in the better services such as public transit and police/fire departments. Downtown is still the center of the economic activities. No sharp contrasts in wealth that are common in US cities.
  • The problems in Canadian cities - integration of foreign-born residents (Vancouver, Toronto, and Montreal…)
  • Differences to US Cities 1) No competing Urban realms
  • 2) Stability and cohesion in urban models not seen in US cities 3) less suburbanization, 4) more use of public transit.
