A public health team records new diagnoses of type 2 diabetes in two health districts during one year.
| Health district | Number of adults | New diagnoses |
|---|---|---|
| R | 240000 | 1080 |
| S | 360000 | 1260 |
Four interpretations are suggested. Which interpretation correctly allows for the different numbers of adults in the two districts?
District S had the higher rate, with 525 diagnoses per 100000 adults compared with 300 in district R.
District R had the higher rate, with 450 diagnoses per 100000 adults compared with 350 in district S.
District S had the higher rate because 1260 diagnoses is 180 more than the 1080 diagnoses in district R.
District R had the higher rate, with 225 diagnoses per 100000 adults compared with 175 in district S.
