Topic
Public statistics are the most fought-over numbers there are, and usually the best documented. The arguments they feed are rarely about the figures themselves; they are about denominators, baselines and which year the comparison starts from.
These clips present the figure with its source and its period attached, show the shape rather than the headline, and leave the argument to you.
Every clip here states its source and the period it covers, and carries the underlying numbers on its page as a table you can copy.
