earth-two-orderings-of-a-regional-decomposition

# Earth: a regional table has two orderings, and both are results `earth-report-the-lattice-and-show-the-field` tells you to build the per-stratum grid and to name and rank the regions that dominate the total and the ones carrying the largest relative change. Follow it. This skill is what that one instruction actually costs, because those are not one ranking but two, over two columns, with two different denominators — and only one of the two denominators is free. A per-region decomposition reported as one absolute column per region is a deliverable that has been computed and not read. Absolute magnitude is the number that says least, because in every regional decomposition this field produces it is dominated by how much of the stock each region holds. The two questions a reader arrives with are which regions supply most of the total, and which regions are changing fastest relative to themselves. The gap between those two answers is what the decomposition is for. ## Three numbers per row, not one 1. **The absolute change**, with its interval, in every unit the brief names. If the brief names two units, both belong in the exhibit; one on the axis and the other in a CSV is one unit reported. 2. **The row's share of the total**, in per cent, with the total stated. This is the attribution column, and it decides where a reader looks. 3. **The change normalised by that region's own stock at the start of the record**, in per cent. This is the intensity column, and it ...
