HIDDIN Information about the Census


The aim of the Census project is to quantify and qualify the Global HIDDIN (Health Informatics, Digital, Data, Information, kNowledge) Workforce, specifically to delineate and count the workforce, consider the future configuration of workforce, identify HIW shortfalls, and identify current health information training and career pathways.

The HIDDIN Workforce Census project is a collaborative project between the University of Tasmania, University of Melbourne, RMIT University, Australian Digital Health Agency, Australian Library and Information Association Health Libraries Australia, Australasian Institute of Digital Health, and the Health Information Management Association of Australia.


Anyone who self-identifies as part of the HIDDIN workforce. You are part of the workforce if you work (including volunteer or actively seeking) in a role where the primary function is related to developing, maintaining, or governing the systems for the management of health data, health information, or health knowledge. As a guide, and not exclusively, this includes anyone who works or provides education and training within the following areas:

  • Biomedical engineering
  • Clinical coding
  • Clinical costings
  • Clinical documentation improvement
  • Digital health infrastructure
  • eHealth systems
  • Epidemiology
  • Health artificial intelligence
  • Health cyber security
  • Health data science/analytics
  • Health informatics
  • Health Information governance
  • Health information management
  • Health information systems or services
  • Health information technology
  • Health innovation
  • Health interoperability
  • Health librarianship
  • Health simulation
  • Health technology assessment
  • Translational bioinformatics


The first Census was held during May 2018. The 2021 Census is currently underway and closes 31 May 2021.

The Census will be held every 3 years thereafter.


The longitudinal study is a sub-study of the census project. The census does not collect identifying information about participants, making it difficult to measure an individual’s career progression over time. As such, the census project is seeking individuals to participate in a longitudinal study of the workforce. If you decide to be part of this longitudinal study, you will be asked to answer a small number of questions at the beginning of each census to enable the project team to link the census response to past census responses. The census questions will follow these questions. Once the census is complete, an individuals’ census responses will be re-identified with a unique identifier to enable individual responses to be linked to past census responses, and then data entered for linkage questions will be removed.

Participation in the longitudinal sub-study is voluntary. You can elect to complete the census without being part of this longitudinal study. A participant who participates in the longitudinal study can elect not to participate in the future.
