What the district is worth, and who holds it.

The vacancy filter on the map colours every lot by this. Bar length is the share of the 277 lots that carry a tenancy.

Emptiest lots: 906-4 (100%), 904-1 (100%), 894-6 (100%), 894-3 (100%), 886-1 (100%), 901-9 (98%), 901-17 (97%), 901-5 (91%)

Bar length is the size of the stock against the largest use; the solid part is what is occupied. So a short full bar is a small use that is full, not a big one.

Cut at the ward's own income percentiles — the middle class begins at the median, the rich at the seventy-fifth, the 1% at the ninety-ninth — so every lot lands in exactly one tier and the top tier holds the top one per cent.

The ward's own lots add up to 25,923,417 gp of owner income against 6,035,900 gp paid out in wages. The workbook totals the same two as 25,870,985 gp and 6,335,100 gp — the difference is the two properties the workbook holds that the source map never drew.

5,824,036 gp of sales a year · 92 employed

7,310,826 gp of sales a year · 81 employed

5,011,505 gp of sales a year · 63 employed

1,802,625 gp of sales a year · 28 employed

2,104,381 gp of sales a year · 16 employed

1,036,491 gp of sales a year · 18 employed

3,739,178 gp of sales a year · 94 employed

6,163,129 gp of sales a year · 104 employed

Every lot is counted once, in its own category, so the totals above are right. These trades are split across two of them, which is why looking for one of these can turn up half its shops. Both places to look are named here.

The five lines below sum exactly to the 26,439,685 gp total. One of them deserves a footnote: residential income tax is levied at 66.7% of rental income that the workbook has already reduced by its 42.63% income-tax rate, so a landlord keeps about a fifth of rent after property tax. Whether both rates are meant to apply is the workbook's open question; this page reports what it computes.
