Why it matters
The value is judged against the median of the same period in up to five earlier years, using a robust measure of spread. A breach means this period sits well outside what those years would lead you to expect.
For major operations, neither a rise nor a fall is better in itself, so the observatory marks this movement as unusual rather than good or bad.
Historical context
Same-period values: 2019 13,216, 2018 13,497, 2017 14,229. This comparison involves the COVID-19 disruption period (March 2020 – June 2021), when service use and reporting fell sharply.
