Population dynamics in rural South Australia.

The authors examine recent trends in Australia in turnaround migration, or the movement of the population from urban to rural areas. "The paper assesses the major changes which have occurred in population trends within the non-metropolitan sector of the nation, South Australia and, in particular, a study area in the lower north region of South Australia. The analysis of the case study region draws upon a survey undertaken in 1968-1970 and partially replicated in 1980 and 1990. It appears that for Australia in general and for the study area the turnaround is continuing but at a slower pace and in a more spatially concentrated pattern."

Urban-rural migration in Australia: a process view of the turnaround.

"This paper summarizes the evidence for the existence of a trend toward population deconcentration in Australia at the macro and meso (national and state) levels. It seeks to relate processes of population dynamics identified at macro, meso and micro levels to several hypotheses which have been put forward to explain the turnaround. A preliminary explanatory model which links causal mechanisms operating at different levels of the spatial and urban hierarchy is outlined."

A process view of the population turnaround: an Australian rural case study.

"This paper provides empirical evidence of local-level demographic and socio-economic changes during the 'population turnaround' decade of 1970 to 1980. The study covers a contiguous area occupied by five small country towns and their trade areas, centred around 80-90 km north of Adelaide [Australia]. These communities were surveyed in detail in 1968 and 1970 in order to make forecasts of demographic change by 1980. In 1980, a replicatory resurvey provided data on various processes of population change operating at grass roots level."

Projecting Australia's aged population: problems and implications.

Issues concerning the projection of Australia's population aged 60 years and over are examined. "The aims of this paper are to examine the extent to which projections made during the 1970s underestimated the growth of the aged population and, more particularly, to establish precisely what the demographic components of that under-projection were. Some of the implications of this analysis for planning provision of services for the aged are then explored."

Accessibility to general practitioners in rural South Australia. A case study using geographic information system technology.

OBJECTIVE: To demonstrate the potential of GIS (geographic information system) technology and ARIA (Accessibility/Remoteness Index for Australia) as tools for medical workforce and health service planning in Australia. DESIGN: ARIA is an index of remoteness derived by measuring road distance between populated localities and service centres. A continuous variable of remoteness from 0 to 12 is generated for any location in Australia. We created a GIS, with data on location of general practitioner services in non-metropolitan South Australia derived from the database of RUMPS (Rural Undergraduate Medical Placement System), and estimated, for the 1170 populated localities in South Australia, the accessibility/inaccessibility of the 109 identified GP services. MAIN OUTCOME MEASURES: Distance from populated locality to GP services. RESULTS: Distance from populated locality to GP service ranged from 0 to 677 km (mean, 58 km). In all, 513 localities (43%) had a GP service within 20 km (for the majority this meant located within the town). However, for 173 populated localities (15%), the nearest GP service was more than 80 km away. There was a strong correlation between distance to GP service and ARIA value for each locality (0.69; P < 0.05). CONCLUSIONS: GP services are relatively inaccessible to many rural South Australian communities. There is potential for GIS and for ARIA to contribute to rational medical workforce and health service planning. Adding measures of health need and more detailed data on types and extent of GP services provided will allow more sophisticated planning.
