#coverage ⧉

How complete is this sector’s count?

242 counted & publishedmeasured coverage 77%

An estimated 77% of this sector’s organisations are counted. The figure is a measurement, not a target: it comes from the same independent comparison the whole census is measured by, restricted to this sector’s rows.

Island-wide, the Bailiwick’s true trading population is estimated at 4,877–5,990, measured on 3 September 2026 by capture–recapture against Google's business listings for the Bailiwick, with every organisation that was itself added from those listings left out of the comparison so the two counts stay independent.

A sector’s coverage is published as a percentage only. The stratum carries no confidence interval, so a sector population would be a point estimate dressed as a range — and the organisations invisible to both the census and the comparison listing pull every such estimate down.

Every count in this chapter is therefore a floor, never a total.

The signature

What this sector actually does

A sector is a label; a capability is a service someone published and we resolved to the graph. 75% of the sector carry at least one, and the typical one among them carries 6.

The same island, drawn on a location quotient: this sector's share of a parish against its share of the island. Hatched parishes hold too few of this sector to compare at all. Parishes holding fewer than 30 of this sector are drawn and tabled but never named in a sentence: a quotient over a handful of organisations moves on one new record, and a superlative that flips that easily is not one.

The sector online

#digital ⧉

86% of Professional Services have a website of its own

Against 67% island-wide — 19 points above the island rate. The gap is the robust part: the sector’s own rate is measured over the organisations we have found, and the ones still missing are disproportionately the web-invisible.

How it's organised

#form ⧉

Legal form, ownership and size — as far as they are published

These are published far less often than a phone number. Each module below states its own coverage, and renders the gap rather than a confident number over a silent base.

Legal form#form-legal ⧉

Professional Services organisations by legal form

A legal form on record for 144 of 242 Professional Services organisations (60%)

On record for 60% — indicative

Sole traders are the systematic undercount here: a limited company publishes its form, a sole trader rarely does.

A further 24 hold something in the legal-form slot that is not a legal form — filing notes, a bare year. Those leave the denominator rather than inflating “other”. Forms held by fewer than 15 organisations are not drawn: below that the bars are a tail of ones and twos, and each one names a handful of identifiable firms.

Ownership#form-ownership ⧉

As each organisation describes itself. Where a parent is off-island, that is recorded only when it was found — there is no “no parent” record, so this is not a count of independence.

Memberships and regulators

What this sector says it belongs to

Memberships, regulatory statuses and certifications as each organisation publishes them, folded to the name they share. This is a text-match floor, not a licensee count — the register itself is the authority on who is licensed.

Published opening hours only; a business that does not publish hours is not counted as closed. 134 hold hours of some shape, of which 124 resolve to a weekly grid and 10 are seasonal or per-site prose that must not be half-parsed.

#method ⧉

This chapter counts over the 242 active organisations whose primary sector is Professional Services — 1 in 14 of the 3,407 with a primary sector on record. The wider 345 who work in Professional Services at all are counted in every sector they work in, and are used only where a sentence says “works in”.

Each module divides by what is actually on record for it: a parish for 223, a founding year for 182, a capability resolved to the graph for 182, opening hours that resolve to a weekly grid for 124. Those bases are printed under every chart, because the denominator is part of the datum.

This sector’s own coverage was measured at 77% on 3 September 2026, by capture–recapture against Google's business listings for the Bailiwick, with every organisation that was itself added from those listings left out of the comparison so the two counts stay independent. Every count above is a floor.

Counts organisations still trading that publish a founding year; older firms are likelier to do so — survivorship and reporting bias at once. Verified from published evidence; businesses without a web presence are under-represented. Capabilities as published by each organisation and resolved to the graph; a business with no capability claim is not necessarily a business that does none of these things.
