Linking people, policy and place:challenges and developments inintegrating socio-economic data intolocational frameworks for betterdecision making. Peter Harper Deputy Australian Statistician Population, Labour and Social Statistics November 2012 – Spatial@Gov
The challenge …‘The work on global geospatialinformation management over thepast two to three years hasconfirmed that one of the keychallenges is a better integration ofgeospatial and statisticalinformation as a basis for sound andevidence-based decision-making.’ Secretary General of the UN Economic and Social Council, 2012.

ABS experience– successes and challenges LAND ACCOUNTS – EXPERIMENTAL ESTIMATES
2011 Census of Population and Housing – changes•New Australian Standard Geographic Classification (ASGS).•Output spatial units different to collection units.•Every addresses allocated to a mesh block – dwelling, place of work, place of usual residence.
Census dwelling address coding :•Collection unit same asMesh Block – 0.5%.•Autocoding system using GNAF– 91.3% direct, 94.2% direct &indirect.•Additional online clerical codingusing GNAF and census collectormaps – 96.7% direct, 97.0% direct& indirect.•Intense clerical review andimputation – 100%
2011 Census of Population and Housing – changes•Statistical Area 1 (SA1) smallest spatial unit for data release.•Increasing demands for data on smaller population groupsand geographies.
2011 Census and the SSF – successes and challenges•Geocoding the population is possible using G-NAF. • Improving G-NAF coverage needs to continue. • ABS needs to assess the acceptability of georeferencing census records from a privacy perspective.•Use of web feature services and machine readable metadata toincrease accessibility to small area data via the internet. • Work done on the SSF to further develop the interoperability of statistical and spatial metadata will be critical here.
Experimental Land Account for the Great Barrier Reef Region•Land Management Practices Survey for the Great Barrier Reef Region during2008/09, in collaboration with the Queensland Department of Environment andResource Management.•The survey sampled land parcels, instead of farming businesses.•The Land Account combined the parcel based data with administrative andspatial data to produce a more valuable dataset.
