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 fully immunised children, 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 98,943, 2018 1,04,682, 2017 1,04,942. This comparison involves the COVID-19 disruption period (March 2020 – June 2021), when service use and reporting fell sharply.
