## Methodology

- **Share of coverage**: an organisation's mentions divided by all mentions of the organisations tracked in the same sector that month, in UK earned media. It is the central measure of media visibility in Omniscan benchmarks. "Average monthly share" is the mean of the monthly shares across the reporting period.
- **Mention**: one article that covers an organisation, classified as positive, neutral or negative in tone. Articles are deduplicated, and an organisation's own websites and passing sponsorship name-checks are excluded, so only earned media counts.
- **Net tone**: positive mentions minus negative mentions, as a percentage of all mentions (range −100 to +100).
- **Themes**: every article is assigned to one of the sector's editorial themes. A theme index above 1 means the organisation is covered on that theme more than its peers are; below 1 means less.
- **Calculation**: every figure is computed directly from the classified articles; narrative summaries are checked against those figures.
- **Sources**: UK national and international, trade and specialist, regional and local, and aggregator and syndication earned media.
