Enhancing microdata access is one of the strategic priorities for the Australian Bureau of Statistics (ABS) in its transformation program. However, balancing the trade-off between enhancing data access and protecting confidentiality is a delicate act. The ABS could use synthetic data to make its business microdata more accessible for researchers to inform decision making while maintaining confidentiality. This study explores the synthetic data approach for the release and analysis of business data. Australian businesses in some industries are characterised by oligopoly or duopoly. This means the existing microdata protection techniques such as information reduction or perturbation may not be as effective as for household microdata. The research focuses on addressing the following questions: Can a synthetic data approach enhance microdata access for the longitudinal business data? What is the utility and protection trade-off using the synthetic data approach? The study compares confidentialised input and output approaches for protecting confidentiality and analysing Australian microdata from business survey or administrative data sources.

Abstract Many statistical agencies face the challenge of maintaining the confidentiality of respondents while providing as much analytical value as possible from their data. Datasets relating to businesses present particular difficulties because they are likely to contain information about large enterprises that dominate industries and may be more easily identified. Agencies therefore tend to take a cautious approach to releasing business data (e.g., trusted access, remote access and synthetic data). The Australian Bureau of Statistics has developed a remote server, called TableBuilder, which has the capability to allow users to specify and request tables created from business microdata. The tables are confidentialised automatically by perturbing cell values, and the results are returned quickly to the users. The perturbation method is designed to protect against attacks, which are attempts to undo the confidentialisation, such as the well-known differencing attack. This paper considers the risk and utility trade-off when releasing three Australian Bureau of Statistics business collections via its TableBuilder product.

This article addresses Aboriginal and Torres Strait Islander health problems and critically investigates current government policies which are attempting to raise the health standards of these Indigenous people. Particular emphasis will be placed on the Queensland Aboriginal and Torres Strait Islander population, which, according to the Australian Bureau of Statistics census in 1986, stood at just over 61,000 or 2.4 per cent of the State's population.

Superannuation is becoming an increasingly important source of retirement income. However, women in Australia face a significant barrier in accumulating superannuation entitlements because of their positions in the paid and unpaid workforce. When in paid work, women occupy lower positions, have more career breaks due to care responsibilities and have more part-time and casual employment. Many women, of course, do not work outside the home, and a smaller proportion of women engage in paid employment than do men. Consequently women have lower incomes, less wealth and less generous retirement benefits. Our analysis of the Survey of Employment Arrangements and Superannuation and other Australian Bureau of Statistics data, together with data published by the Australian Prudential Regulatory Authority, reveals that dramatic policy initiatives will be needed to improve women’s access to retirement resources. Such policies do not apply only to superannuation but must address women’s positions in the paid workforce and their care responsibilities.

If we try to increase the level of automation in enterprise application integration (EAI) scenarios, we confront challenges related to the resolution of data and message heterogeneities between interoperating services, which traditional EAI technologies are weak to solve. We propose a semantically-enriched approach for dynamic data mediation in EAI scenarios, focusing on the resolution of message level heterogeneities between collaborative enterprise services, facilitating automated data mediation during execution time by providing formal transformations of the output and input messages (of the participating services) to a common reference business data model, that is, the enterprise interoperability ontology. Moreover, we present a tool that has been developed to support the user to provide business data-related semantic annotations and XSLT transformations of the input and output message parts of collaborative enterprise services. Finally, we demonstrate the utilization of the proposed approach and toll in a real-world EAI scenario.

When graziers are required to pay a rate in proportion to the number of livestock they declare, some tend to reduce the number declared. In western New South Wales discrepancies exist between livestock numbers reported to local Pastures Protection Boards for rating purposes and those collected by the Australian Bureau of Statistics. The size of the discrepancy is considerable. Other systems of collecting revenue may be more efficient and more equitable. Data obtained from livestock rating systems provide an accurate indication of trends in livestock numbers but do not give an accurate assessment of the total number of livestock within an area

In this article, we use the five-yearly census of occupations to develop an historical perspective on Australian journalist employment from 1961. We do so for two reasons. First, we gauge the impact on journalist employment of online media from 1996 and media platforms since 2006 comparing these to previous media transformations. Second, we explore journalism and its occupational profile noting its close connection with authors and public relations professions. To allow for a period when the Australian Bureau of Statistics placed journalists and authors together as in a single occupational grouping (from 1961 to 1981), we track their combined employment from 1961 to 2016. From 1986, we consider journalists and authors separately. In each case, we consider numbers employed, their respective proportion of the workforce and their compound annual growth rates establishing the extent to which employment grew above – or fell below – that of the workforce as a whole. We show the gradual recalibration of journalists and their writer–author counterparts with respect to each other. From 1996, we outline the performance of different kinds of journalist over the 20 years to 2016 covering both online’s first open Internet decade and its second closed media platform from 2006 to 2016.
