National Centre for Longitudinal Data


"We have to see evidence of success as points of light all around us and join them up to create a universe of opportunity for our children. These results from the Footprints in Time data provide more points of light."  Professor Mick Dobson AM Director National Centre for Indigenous Studies, Australian National University

Our mission

To promote a longitudinal evidence base that informs policies and practices to improve the lifetime wellbeing of people and families in Australia.

To achieve our mission the NCLD will:

  • develop a national framework (or architecture) for government investment in longitudinal data
  • produce and manage quality longitudinal data sets and encourage their use
  • foster collaboration between longitudinal survey developers, researchers and policy makers
  • facilitate broader use of longitudinal data

About longitudinal data

Longitudinal data is data collected from the same individuals (or households, businesses or other entities) repeatedly over time. The data is able to show how actions and events can affect outcomes later in life.

The Longitudinal Studies and the National Centre for Longitudinal Data (NCLD) fact sheet explains the the value of longitudinal data, and particularly how it can support decision makers to address critical questions.

The Centre's studies

The NCLD brings together longitudinal surveys managed within the Department of Social Services.

The four active longitudinal surveys managed in the NCLD are:

These studies each follow their own cohort of people through various stages of their lives, charting social change and exploring the reasons behind it.

Access to DSS longitudinal datasets

Information regarding access to the data sets of the Centre studies is available at Access to DSS Longitudinal Datasets.

Please note that the NCLD is currently reviewing access arrangements for its four study datasets. This includes assessing the feasibility of removing or reducing the current data access fees.

Currently the existing data access fees and data access arrangements remain in place. If your application will incur a cost (i.e. all applications for Individual Deed of Licence) and you do not need urgent access to these datasets you may wish to delay your access request until the review has been finalised.

Centre research and publications

The Policy Evidence Branch is involved in a wide variety of research projects involving the analysis of longitudinal data and the development of longitudinal research methodology.

The Centre research and publications page details recent research, including Research Summaries, Data Highlights, Technical Reports, Annual Statistical Reports and Study Annual Reports.
