Town A recorded 120 service requests. Town B recorded 80. A headline could correctly say that A had more requests, but it could not yet say that an individual resident was more likely to make one.
For an illustrative calculation, suppose A has 60,000 residents and B has 20,000. A’s count is 2 requests per 1,000 residents; B’s is 4 per 1,000. The raw ranking and the population-adjusted ranking point in different directions because they answer different questions.
- Choose the count and the population for the same place and period.
- Divide the count by the population.
- Multiply by a stated scale, such as 1,000 or 100,000.
- Keep that scale visible beside the result.
These fictional figures demonstrate arithmetic, not a finding about any real town. They also show why both numbers can be useful. A service manager may need the total workload, while a comparison of participation may need a population-based measure.
| Illustrative town | Requests | Residents | Requests per 1,000 |
|---|---|---|---|
| A | 120 | 60,000 | 2 |
| B | 80 | 20,000 | 4 |
Keep the table’s two comparisons separate when writing about it. “A handled more requests” concerns workload. “B recorded more requests per 1,000 residents” concerns the rate under this population definition. Neither statement establishes that residents were more satisfied, that the service was worse or that the requests were equally serious. Those explanations would require further evidence.
The denominator still needs scrutiny
Residents may not be the right population for every question. A transport hub serves visitors; a school programme serves eligible pupils; a clinic may accept patients from outside the district. Ask who could actually generate the event being counted.
Check whether the numerator counts people, visits or repeated reports. One person making five requests is not five different residents. Keep definitions consistent before comparing two sources.
Small populations can produce unstable-looking rates when only a few events change. Do not hide the underlying counts, especially when the difference between places is only one or two cases.
A clear sentence includes the period, measure and scale: “The town recorded four requests per 1,000 residents during the year.” It leaves room for the next question—why the figures differ—without pretending that dividing by population has already explained the cause.
