UK Employment Landscape

Employee data comes from two sources: Wikidata (verified counts for major employers) and Companies House annual accounts (size brackets). The Wikidata dataset provides exact headcounts for approximately 860 large companies including FTSE-listed firms, major retailers, and public sector organisations.

Companies House accounts provide employee size brackets (micro, small, medium, large) for over 2 million companies. While less precise than Wikidata, this gives broad coverage of the UK employment landscape.

Supermarkets, banks, and public service organisations dominate the top employer rankings. Many large employers operate through subsidiary structures, so group-level employment may be significantly higher than individual entity figures.

Frequently Asked Questions

Where does employee data come from?

Employee counts come from two sources: Wikidata (exact headcounts for ~860 major employers) and Companies House annual accounts (size bracket classifications for 2M+ companies).

Why are only ~860 companies listed with exact counts?

Exact employee counts are sourced from Wikidata, which covers major public companies, FTSE-listed firms, and notable employers. Most UK companies only report size brackets (micro, small, medium, large) in their accounts.

Do these numbers include subsidiaries?

Generally no. Employee counts are per legal entity. Large corporate groups may distribute employees across multiple subsidiaries, so group-level employment may be significantly higher.
