Methodology & sources

Every premium figure on this site was read off a published source on 2026-11-11 and is stored with its source, its coverage profile, and its access date. We never blend figures from different sources into a single number, and we never publish a premium we could not source.

What we don't publish

Freshness

Premiums rose about 11.5% for dogs in 2025 (NAPHIA). We refresh this dataset quarterly; the collection date appears in every page footer, and stale cells are re-sourced or removed, never quietly carried forward.

Corrections
