What a record here means, and what it does not

It means: of the periods this site holds for the series, since its last methodology break, no other period carries a larger (or smaller) published figure. It does not mean the highest or lowest ever measured; earlier periods may exist that the publisher no longer publishes on a comparable basis, and a methodology break ends the stretch a record is taken within. Where an earlier period holds exactly the same figure, the row says the record was equalled rather than passed.

Money is in cash terms unless the publisher deflated it, so a record in pounds is a record in that period’s money. Counts are records of counts: a population that grows makes records in counts more common, which is why the site also publishes rates where a denominator exists.
