According to this portal's Publishing Organization, this page was last reviewed in August 2026 against our methodology. Figures and extracts on this site, including tables above 1,000 rows when the corpus is that large, are the publisher's responsibility.

Every figure published on PlainTaxData is traced back to its official public source and computed by deterministic pipelines, not hand-entered. Our methodology sets out exactly how each dataset is sourced, computed, and refreshed, and the about page explains how we handle corrections when a reader flags something. The byline below is the publishing organization itself, not an individual writer: these pages are generated from documented pipelines rather than individually reported, so accountability for the framing and for correcting it sits with the publisher.

PlainTaxData is a data-journalism publisher: we compile public datasets, verify them against their official sources, and present them in plain language. Editorial standards, sourcing, and how we handle corrections are described on our about and methodology pages.
