A fact check on a dated figure or statistic against the publisher's own series
A fact check on a dated figure or statistic against the publisher's own series: verified, stale, contradicted or unknown, with the as-of date. Relevant wherever a number is going onto a page, deck, model or decision. Coverage today is Australian primary sources; anything outside coverage returns unknown rather than a guess.
