Peri-urbanization? Counter-urbanization? Multi-
functional landscapes?
Peri-urban Conference October 2013
A broad conception of a region:
Areas directly ‘urbanising’
Areas influenced by urban-generated land markets
Areas influenced by various modes of ‘counter-
urbanization’
Amenity, accessibility, affordability – an interplay of factors

Socio-economic processes are varied…
La Trobe University
A series of processes emerge from the literature and empirical
work, including:
Exurbanisation: higher cost land markets, purchasing an
accessible rural lifestyle
‘Displaced’ suburbia – suburban growth performed beyond
the fringe
Retiree mobility – at varied income levels
‘Welfare-led’ migration, especially in the high-cost
Australian metropolitan housing markets
These overlap socially and spatially

Our approach
La Trobe University
Considering a geography of these processes of change in a
geographically wide ‘peri-urban’ field
Using a set of proxy indicators to test change – based on
inward migration 2006-2011
Considering the relationship between these, and relationships
with a set of location factors of ‘attraction’
Testing indicators and concepts – are they fit for purpose?

The data sources
La Trobe University
Census 2011:
usual residence 2011 for those with a different SA2
address in 2006
Cross-tabulated with selected socio-economic
categories (age, income, occupation)
Location database (GIS):
Developed from a lot/property-based attractiveness
index of development ‘pressure’
Average scores (indexed) aggregated for all within each
SA2
12
The indicators
La Trobe University
high income
‘professional’ occupations
low income
unemployed
age 55-74
not in labour force
age under 15 years
‘driver/labourer/machinery
operator’ occupations
average proximity to main
roads
…proximity to rail nodes
…proximity and density of
native ‘woody’ vegetation
…proximity and density of
‘landscape’ features (SLO,
ESO, Parks)

Geography of Indicators
La Trobe University
Clusters of each type; good correlations between them

Location and socio-economic change
La Trobe University
Regression models: location factors as dependent, all models
show significance, but..
Some variables (professionals, higher income,
children/families) show better influence than others
Professionals – landscape
Higher income/u15 – non-vegetated regions
Lower income and rail, retiree and non-rail
21
The limits to attractiveness
• Issues in understanding aggregate ‘attractiveness’ factors
• Complexity and inter-connections of social and economic
processes
• New in-migrants and relationships to extant populations
• Relationships between peri-urbanization, counter-urbanization
and the formation of multi-functional landscapes
