Keir Clarke from Google Maps Mania has just written a short post on the SBS - Census Explorer. So far it remains the only substantial mapping applications for exploration of the key demographic indicators from Australia's 2011 Census.
The tool allows users to interrogate the census data and visualise on the map the number of persons using one of several dozens of different languages spoken throughout Australia. Using a drop-down menu it is possible to select an individual language and a coloured thematic drape indicating concentration of people speaking that language is then displayed on the map. By clicking on individual suburbs users can get the exact number of the language's speakers at that location.The application has also a handy functionality which allows to compare two language groups for a given location.
