1. Developing the Statistical Spatial Framework
2. Summary of the Framework
3. Australian application of the Framework
Changing information environment
• Growing demand for geostatistics
- for smaller areas
- more variety in regions, greater flexibility
- geostatistics from administrative data
- opportunities from big data & open data
• Maturing geospatial data infrastructure
• National statistical leadership role in geostatistics
How do government agencies use
or want to use spatial information?
Developing and evaluating policy
• Understanding clients and their locations
• Modelling or determining impacts by region
Administration of programs
• Contracts based on operations within regions
• Use of spatial analysis in fraud control
Reporting
• By many areas, e.g. state, electorate, postcode, LGA,
statistical areas, departmental specific.
• Open data and data for national statistics
ABS - a strong geospatial history

2. Summary of the Framework
SSF Vision
SSF Goals
Informed decision making is enhanced
by using location in a common framework
to allow seamless integration of administrative,
statistical and spatial information resources.
All statistical data
is consistently
spatially enabled
Users can discover, access,
integrate, analyse and visualise
statistical information seamlessly
for regions of interest
The Framework
Australian application of SSF
Policies, standards and guidelines support the release,
Accessible access, analysis and visualisation of geostatistics.
& Usable
Interoperable
metadata
Use international statistical and
geospatial metadata standards
- further development required.

3. Australian application of the Framework
Address on census night,
Census coding
• Autocoding using GNAF
– 91.3% direct coding
– 94.2% with reprocessing
• Additional online clerical
coding using GNAF and
census collector maps
– 96.7% direct clerical
– 97.0% with reprocessing
• Intense clerical review
and imputation
– 100%
