The Data Acquisition and Collection program provides a comprehensive statistical data collection service for the ABS that also encompasses administrative data acquisition. The program is leading the Acquire@ABS program to transform collection operations through the introduction of an online reporting capability that will include the first online Census of Population and Housing in 2016. In doing so, it supports ABS objectives by providing a high quality, timely and cost-effective service while maintaining the trust and cooperation of providers through a range of measures, including: efficient and effective data collection operations; developing and maintaining a skilled and committed home and office-based interviewer workforce upholding the confidentiality of information provided to the ABS; and continually improving the processes and instruments for ABS interaction with providers.
Key achievements in 2014-15
- Improved processes were implemented to increase response rates in the Monthly Population Survey, with significant improvement in the rate and consistency in the Northern Territory while maintaining response rates in other states.
- Response rates were improved for remote Aboriginal communities participating in the National Aboriginal and Torres Strait Islander Social Survey collection.
- The program continued stabilisation of systems, including providing new technology to our field force, improving the work health and safety system and enabling improved quality processes.
- Work continues to improve the provider experience:
- The e-form implementation project, started in 2012 to introduce a new online collection mode, was completed in October 2014. This project has resulted in ongoing high take-up rates for the majority of ABS business surveys and over 30% of household respondents now interacting through the online form.
- A new authentication process has been introduced for users of e-forms which meets industry standards and facilitates self-service functionality for survey respondents.
- The online Census Instrument capability was developed for the digital-first 2016 Census, to support two-thirds of the Australian population reporting online.
The Analytical Services program conducts research and development in analytical methods to support the production of high quality and trusted statistics, manage and mitigate statistical risks, and exploit opportunities presented by the emerging information economy. Key focus areas for the 2014-15 work program include data integration, confidentialisation, and innovative analytical methods for both traditional and emerging data sources.
By providing analytical support and methodological advice, the program contributes to the delivery and continued improvement of ABS statistical outputs. For example, the advancement of data integration and analysis methodologies underpins the creation of a richer, more dynamic and focused statistical picture of Australia for informed decision-making. Dynamic data confidentialisation methods and improvements to microdata access requirements make data more widely accessible while robustly protecting the confidentiality of information provided by individuals or businesses. The production of time series in seasonally adjusted and trend form are an important input to policy formation, decision-making and research. Examining big data sources helps position ABS to capitalise on the opportunities presented by emerging data.

- Assisted the Department of the Treasury and other Australian Government departments involved in redeveloping a static microsimulation model of the income tax and transfer system.
The Data Standards and Methods program is responsible for promoting the comparability, integration, coherence and quality of ABS statistics, through the use of standard concepts, definitions, classifications and procedures. It is also responsible for the infrastructure used to hold key definitional metadata and to store statistical data from which ABS outputs are sourced.
Key focus areas of the program are: transformation of statistical metadata into future ABS infrastructure; the modernisation of the ABS Data Management framework for transforming statistical data into future ABS infrastructure; and the development of new mathematical, statistical and computational methods to enable future ABS analytical and processing capability.
Key achievements in 2014-15
- Data governance framework and strategies for managing data in an integrated data management environment were developed.
- 2016 Census coding indexes for Occupation, Education and Industry were delivered.
- A reference set of definitional standards and taxonomies was published as part of the delivery of Deputy Secretary Efficiency Working Group Initiative 9 – Develop Standard Definitional Taxonomy. The reference set includes financial, demographic and welfare data definitions and includes key ABS standards. The reference set was provided to government, through GovShare, to ensure better and more coherent collection of information.
- Twenty standards were published on the ABS website.
- A prototype was developed to demonstrate new methods and semantic technologies for representing, discovering and visualising complex information such as cross-sectional and longitudinal data derived from diverse survey, administrative and big data sources, to solve challenging policy analysis problems in the areas of firm-level productivity, labour market dynamics, and regional economic activity.
- New techniques in machine intelligence were applied in developing an improved automated coding system for complex classifications to improve the speed, accuracy, consistency and cost-effectiveness of coding textual fields in survey and administrative datasets.
The Statistical Services program provides specialist services to meet new and ongoing demands in official statistics.
The program supports the statistical collection and production processes, and provides leadership in developing the future methodological infrastructure of the ABS.
The program also minimises the load on data providers through efficient data collection methods, sample designs, techniques to control sample overlap between surveys and, in the case of Australian business surveys, through reviews and approvals by the Australian Government Statistical Clearing House.
