Learn more about your state, your region, your LGA, your postcode, your suburb or your local neighbourhood, all from a single map.
GeoDemo gives you access to 2006 Census stats from the state level down through 7 layers of boundaries to your neighbourhood (CCD) area.
Note: Requires Silverlight.
If you’re on a diet and want to go plug-in free: try the JavaScript only version: http://www.minus34.com/demo/




Congratulations on a good entry. I think it is one of the more intuitive mapping entries.
Thanks! It’s always tricky getting the interface right when trying to create easy access to relatively complex datasets.
Nice work with this. I think the ability to easily see down to neighbourhood level is fantastically useful, and although I like that you’ve made a decision on what level to display at what zoom, it’d be nice to have some control over that.
This has a lot of potential, and with a bit of extra work, it’d be a perfect tool for people looking at areas to move to within a suburb.
Cheers!
The control over which boundary to display is a good issue to raise, but its a fiddly one to solve.
You’d have to still impose some limits on what a user could see at what level due to client hardware and map performance limitations.
Currently in JavaScript, the limit is about 200 polygons with 2000 sets of coordinates in them. This is for IE. For Firefox and Chrome, and all browsers with Silverlight – the figure is higher, but is still client hardware dependant.
In a few years time, we’ll hopefully have no problem displaying all ~35,000 CCDs in a single map in any browser. I heard yesterday that IE9 will have graphics acceleration, so here’s hoping the laggard comes good…
Awesome Work Hugh, 5 stars!
I think you will find that it will be less then a few years
Good work Hugh
It’s great to see a mashup that actually involves smarts and some effort as opposed to just displaying points on a map. It was a big hit in our office.
Thanks John, Josh!
I did dots on maps a while back… Interactive polygons are much more fun when you’re a geo-geek.
Top notch entry – best I’ve seen so far.
Thanks alot Damon!
Wow. This is an awesome census visualisation application. Congratulations on a 5 star entry!
An enhancement request is the ability to “pin” the census details (eg, hovering over a polygon shows the results, but clicking on the polygon freezes the results until the next click) and allowing copy/paste of the results.
It would also be great to show multiple types of information. The current viewer shows Age and Income – what about a Transport option which showed number of cars, how they get to work, etc. Then a Language option which shows language spoken, a Religion option, etc? This could be a dropdown menu on top of the Select Map Theme dropdown, which would change what was displayed and reported.
Once again, congratulations on a winning entry.
Thanks!
The sticky info or pin the info down suggestion is good. FYI – I got to improve the way the popup data is displayed in my other entry:

For the first cut of GeoDemo – I wanted to keep the stats simple. The framework’s there to handle any number of ABS Census stats, so I plan to add the rest of the basic Community Profile after this comp.
Cheers,
Hugh
Also, if possible, it would be nice to automatically assign a relevant colour scheme depending on the variable being mapped.
eg, when showing income levels, low values should be red; when showing population levels, high values should be red.
ie, if it is a “negative” attribute then the colour scheme should be reversed, so you can quickly see the areas which require attention.
Good work!
It was a bit slow on my browser but I really liked this!
