Analytical tools for the interrogation of inter-regional migration flows and matrices

Analytical tools for the interrogation of inter-regional migration flows and matrices

This project will produce a set of generic analytical tools for the interrogation of inter-regional migration flow matrices at a variety of spatial scales. The project delivers an eResearch tool with the capacity to compute statistical metrics that capture three key dimensions of mobility: (1) migration intensity; (2) migration impact, and; (3) direction of migration. Results from these computations can then be presented in the form of tabular output and summary metrics, as well as cartographically and graphically to capture key dimensions of migration flows.

The eResearch tool will facilitate interrogation of the ABS Journey-To-Work (JTW) data.


Project Overview

This set of generic analytical tools will facilitate the interrogation of inter-regional flow matrices at a variety of spatial scales. The eResearch tool will permit the user to analyse databases containing a variety of population flows (e.g. inter-regional migration, journey to work) uploaded to the AURIN infrastructure to generate summary measures. These can then be graphed, tabulated and mapped using the broader AURIN-wide capabilities, or exported to other software environments (e.g. ArcGIS and Stata) for reporting purposes and/or further statistical analyses.

Expected users of this tool include researchers with demography, regional science, transport and human geography backgrounds.


Project Outputs

The eResearch tool will facilitate interrogation of three major Australian repositories of population flow data:

  1. The Australian Internal Migration (AIM) database, developed by the Queensland Centre for Population Research. This database holds internal migration flows between 69 temporally consistent Statistical Divisions (TSDs), captured at each Australian Census since 1976. Data are derived from the Census 5 year migration question, that is, where did the respondent live 5 years ago. Data are available by 5 year age groups and sex.
  2. Other migration flow data from the Australian Census of Population and Housing, access to which will be negotiated through the broader AURIN data framework. Data might include, for example, migration matrices for movements between the new statistical geography of Statistical Area 2s, SA3s or SA4s.
  3. The eResearch tool will facilitate interrogation of Journey-To-Work (JTW) data from the 2006 and 2011 Australian Census of Population and Housing, (access to which will be negotiated through the broader AURIN data framework) for Statistical Local Areas and Statistical Level Area 2s respectively. Statistical metrics draw upon previous published research by Bell (Bell et al., 2002) and Corcoran (Corcoran et al., 2009a; 2009b) to measure three key components in inter-regional migration matrices; (1) intensity of migration; (2) migration impact, and; (5) direction of migration. Outputs from the statistical measures have the potential for tabulation, graphing and mapping drawing upon AURIN-wide capabilities.

 


Project Team

Dr Jonathan Corcoran, Prof. Martin Bell, Dr Elin Charles-Edwards and Mr Jim Cooper are all based within the Queensland Centre for Population Research (QCPR) within the School of Geography, Planning and Environmental Management at the University of Queensland. The Chief Investigators (CIs) all have extensive experience in pure and applied research, and provide education and training in demography and population geography. The work of the Centre focuses on migration and population forecasting both within Australia and overseas, and encompasses theory, methodology and empirical analysis.

For the purposes of the development of the AURIN eResearch tool, the CIs have partnered with the Queensland Cyber Infrastructure Foundation (QCIF) to translate the analytic work on migration data into an eResearch environment compatible with the AURIN framework.
