👁️🗨️ How Unique Are You?
Discover how easily you could be identified from supposedly "anonymous" data. Even after removing names and addresses, organisations can still re-identify individuals using just a few basic demographic characteristics.
Understanding Your Risk: We show how many people share your demographic profile. Smaller groups mean higher re-identification risk in "anonymous" datasets.
● Very High Risk: Less than 10 people
● High Risk: 10-99 people
● Moderate Risk: 100-999 people
● Lower Risk: 1,000+ people

⚠️ Educational Purposes: The risk calculations presented by this tool are estimates for educational purposes and should not be considered exact measurements. Real-world re-identification risk depends on many factors beyond basic demographics, including the specific datasets being linked, the sophistication of matching algorithms, and additional available information.
About This Calculator: This tool uses Australian Bureau of Statistics (ABS) census data to demonstrate re-identification risk in anonymous datasets. By analyzing how many people in your postcode share your age group and gender, it estimates how easily you could be singled out.
