Types of Communities and Urban Sprawl
Urbanization has three main definitions you will need to know for the exam:
The proportion of a country’s population who reside in urban Settings80% of India’s population still reside in rural settings, 20% lives in urban settings The movement of people from rural to urban areasMany people move to the Halifax Area from rural nova scotia for various reasons, (examples: work, education, etc.) The physical expansion of townsHalifax is creeping out further and further because of a population increase.
Central Place Function: This community is a hub for services to smaller communities around them.
Specialized Function: These communities have an unusually large percentage of their labour force employed in one type of work
Break of Bulk Communities: These communities are used for “transshipment,” or as a hub for goods.

“The spreading of urban developments (houses and shopping centers) on undeveloped land near a city”
“The growth of neighborhoods where people live and shop.” - Mr. D. Smith
Problems1) Land use conflicts- There might already be
something near a new residential development that residents would not appreciate. They will move in anyway and then complain when they notice the problem.
2) Social conflicts: New people may not mix with the original people, may expect different things.
3) Inefficient land use: Laws aren’t ususally ready to adapt to new residents and the desires they bring in, so the market decides how land is used.
• Big expensive residential properties instead of farm land
• necessary wetlands or habitat destroyed for mini-malls and car dealerships
• Etc.
4) Increased energy consumption.How does living in a suburb need more
energy than living in a city?
5) Increased financial burden: People move out of the city and so their money often goes with them
• Purchasing goods and services• taxes
Solutions• Higher density housing
•Improve and encourage public transit,cycling, and walking
• “Green-up” parks libraries, ban new highways

• Co-housing – reduces cost and keeps people in the city
• Build up instead of out to provide inexpensive housing
• Mixed activity areas houses, shops, businesses, offices
