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 C-section share of institutional deliveries, 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: 2020 2.1%, 2019 2.8%, 2018 3.1%, 2017 2.6%. This comparison involves the COVID-19 disruption period (March 2020 – June 2021), when service use and reporting fell sharply.
