settlement pattern
The way buildings and communities are arranged on the land: clustered, linear or scattered (dispersed).
population centre
In Statistics Canada's definitions, an area with at least 1,000 people and a density of at least 400 people per km². Areas outside population centres are rural.
census agglomeration (CA)
A smaller urban area with a core of at least 10,000 people (Statistics Canada).
seigneurial system
The land system of New France: long, narrow lots running back from a river, so each farm had river access.
concession system
Ontario's survey system: land divided into rectangular lots along straight concession roads, crossed by sideroads.
Dominion Land Survey
The Prairie survey system: square townships divided into 36 sections, each one mile (about 1.6 km) on a side.
urban sprawl
Low-density growth spreading outward from a city, usually car-dependent.
informal settlement
Housing built without legal permission or services, often on the edges of fast-growing cities in lower-income countries.
