Then and now

The same measure at two dates, area by area

Each page takes one published figure for every area at two dates, draws both dates as maps on one colour scale so a shade means the same figure in each, and lists every area with the change between them. The figures and the dates are the publisher’s; the change is arithmetic. Each page says what the pair establishes and what it does not.
