Data Sovereignty in a Health Poster
A student is making an awareness poster about ear health among Aboriginal children for a school health week. The student finds a small community survey reporting that 18 of 40 children in one town had recurring ear infections. The survey was conducted by a local health service and shared with the school for planning purposes. The student wants to put the 18-of-40 figure on the poster, name the town, and add a line saying the problem is 'widespread and worsening'. A health worker asks to see the poster before it goes up.
1. Assess the student's planned use of the survey data.

Several problems arise. The survey was shared for planning, not for public communication, so its use on a poster may exceed what the health service intended. A sample of 40 children in one town cannot support a claim that the problem is widespread or worsening; the data shows a local proportion at one point in time.
Naming the town with a health statistic risks stigmatising a small community and may allow individuals to be identified in a small sample.
The student should treat the health worker's request as a necessary check and revise the claims to match what the data actually supports.
2. Propose a revised poster that uses the data responsibly.

A responsible version would:
- Remove the town name and present the figure as an illustrative local example, if the health service agrees.
- Replace 'widespread and worsening' with an accurate statement such as 'ear infections affect many children in some communities'.
- Attribute the figure to the health service and note the small sample.
- Focus the poster on prevention and access to care rather than on alarming statistics.
This keeps the message useful while respecting the conditions under which the data was shared.
3. Explain why the health worker's review matters even though the student has no bad intent.

Intent does not determine impact. The health worker knows the community context, the limits of the survey, and the risk of identification or stigma. Review by those who own the data is a check on how information about a community circulates, and it is a reasonable condition when data is shared for a limited purpose. Accepting the review strengthens the poster's accuracy and maintains trust between the school and the health service.
