Introductions The last census was conducted by the Australian Bureau of Statistics (ABS) on the night of 9th August 2011 and the next census is scheduled to be conducted in August 2016. The first release of the census data is typically scheduled six months after the census night and the second release around one year after census night. The unavailability of population counts data in between two censuses presents the need for understanding population changes in the intervening years.
Based on the current availability of relevant data, Spectrum Analysis has produced small area population projections for the following years:
Methodology Spectrum’s Population & Household Projections take into account birth rate and mortality rate of the area, the number of building approvals by building type classification in the area, and the average number of people typically residing in each building type in the area.
The Population & Household Projections that have been produced for each post-census year have been calibrated against the ABS’s Estimated Resident Population (ERP) data (where possible) that is published for every Local Government Area (LGA) in Australia. This is to ensure that the sum total of population counts of all the small areas (Statistical Area 1, or SA1) within each LGA match with the ABS’ projections, and thus provide a certain level of confidence in the accuracy of projections.
