With the rise of open data, more government information is available today than ever before. Yet much of what has been made available so far is just the “low hanging fruit” of open data: non-sensitive data that can easily be distributed through open data portals, without the publisher needing to consider privacy and confidentiality issues.
Many higher value datasets, such as financial or health related information, have remained locked away due to privacy concerns. Where this type of data is available, it is typically in a severely restricted format or heavily pre-aggregated. By its nature, this limits the usefulness of that data.
At Space-Time Research, we have sophisticated confidentiality and statistical disclosure control routines built right into our product suite. Our tools apply statistical disclosure control automatically and on-the-fly, helping to maintain the delicate balance between releasing data that is flexible enough to be useful, while protecting the privacy of the individuals in that data.
The Australian Tax Office publishes an annual report on taxation statistics that provides lots of valuable information about the financial state of the nation. It also releases some raw data, in the form of a small representative sample of all tax returns for each year.
To get an idea of the power that a tool like SuperWEB2 could bring to the taxation data, were the full data to become available, we loaded the sample data provided for 2003 – 2014 into our suite. You can check out the data for yourself in our online open data demo, or browse some of the stats we uncovered below.
While mean incomes for each of the states have fluctuated over time, it’s interesting to note the effect of the mining boom on Western Australia. In the 2012-2013 tax year, for the taxpayers represented in the sample data, the mean income of WA taxpayers overtook those in the ACT for the first time:
For most occupations, mean deductions seem to peak between the ages of 20 – 30 and then start to decline. “Managers” represented in the sample data seem to be a notable exception:
The older you are, the more likely you are to use a tax agent to prepare your return:
SuperWEB2 is a superior way to share data with any audience: allowing anyone to ask questions of the data, and visualise the results, simply by dragging and dropping. It has access to our sophisticated confidentiality and disclosure control solutions, allowing you to publish sensitive data while protecting the privacy of the individuals in that data.
