Hi Roger,
Michael is correct (thanks Michael!), but here is a bit more detail to add to his comments:
The Australian Bureau of Statistics (ABS) collects Census data in small blocks called Collection Districts (CDs). CDs are the finest geographic detail available to us when we prepare the statistics in your Community Social Profile.
Using records from the Diocesan Registry, the ANGLICARE Policy Unit has, over many years, built a map of the Diocese in which these CDs are combined to create areas that match each parish as closely as possible. Each CD is uniquely ascribed to a single parish. ANGLICARE, a primary sponsor of NCLS Research, provided these records to NCLS Research in order to produce the Community Social Profiles.
Some differences, like the ones you’ve described, are probably just a result of the fact that CDs don’t match parish boundaries perfectly. We have made decisions about which parish a CD is allocated to using all the information available to us, including boundary records from the Registrar, CD boundaries from the ABS, church location information, and street network data.
If parishes think their boundaries are significantly in error on their Community Social Profile, then they are welcome to contact me on nswann at anglicare dot org dot au. The Community Social Profile gives you some of the most relevant data from the Census, but I’m more than happy to talk to parish representatives about accessing data directly from the ABS website if they want to dig a bit deeper and don’t know where to start.
NCLS Research can also produce Community Social Profiles based on any radius around a centre-point you specify (e.g. your church), feel free to get in touch with NCLS Research directly for more information.
