Hi all,
I have recently been doing some demographics and population health stuff at work, using census data and MapInfo. We are currently collaborating with various health providers, so as a result I have tons of census data in a number of areas.
People often mention an interest in buying in certain areas / avoiding lower socioeconomic areas / where to buy to avoid crime etc. So I thought, seeing I have a fair bit of this data (and a boring week ahead at work ) I'd see if I could map some of these things in a way that might be useful.
First cab off the rank, I've knocked up a few maps detailing the SEIFA Advantage / Disadvantage score for postcode.
The Socio-Economic Index for areas 2001 (SEIFA) is derived from the 2001 Census of Population and Housing, and provides a range of measures to summarise aspects of the level of socio-economic wellbeing in an area. One measure is the Advantage / Disadvantage index:
“a continuum of advantage to disadvantage and is available for both urban and rural areas. Low values indicate areas of disadvantage, and high values indicate areas of advantage. It takes into account variables relating to income, education, occupation, wealth and living conditions.”
Australian Bureau of Statistics. Socio-Economic Indexes for Areas 2001: a comprehensive profile of the Australian People. Canberra: ABS.
The baseline score for the index is 1,000, which is the median for all Australia. Ive chosen this index because it is actually a combination of the other individual indices (income, education etc). The higher the score, the more advantaged a suburb is based on the above factors.
Below are the maps I created for Sydney, Brisbane and Melbourne detailing the Advantage / Disadvantage scores for each postcode. When I get a chance (tonight or sometime tomorrow) I'll finish doing them for each of the other state capitals. I'm still fiddling with the scale and shading, so if I decide to change anything on the current maps I'll update them here. Its quite hard to get the right combination on the scale to encompass a lot of suburbs while still detailing the differences between them.
The maps are based on the 2001 census - until late next year when the 2006 census data is out, it is the most recent data I have. As such, the maps can only detail what is in the data. If areas have gone through gentrification, population changes etc recently, then this will not show up.
Once I've finished the advantage index maps, I'll see what other interesting things I can come up with. A few might be things like employment, crime, housing stats etc.
Firstly, before I start doing more, are these things that people might find useful?
I might also take requests if people can provide data they have - for instance, if someone has median price movements for certain suburbs / cities over time, I can map those. They would be much like the ones in past issues of API, but could be more interactive and current (if the data is), and go into greater detail.
Anyway, post away if you have any thoughts on anything above. The maps will have scaled in the post and some postcodes might be hard to see, but are available full size in the photo gallery if you want to save any to your own hard drive.
