Most roles in force
Roles the register still carries as valid, not ones that have ended.
This is not a wealth ranking.
Revenue belongs to the companies a person is recorded at, whatever share they hold. A board member of a large company appears here with that company's entire turnover, which says nothing about their own income. The register also carries no identifier for a person, so people are separated by name and town — and even then more than one person may be involved.
The rankings fill up once the people index has been built.
