Method and sources

Average annual growth of staff (FTE) over three financial years, the way the OECD measures high-growth firms: at least 10 FTE at the start, four consecutive annual accounts and a plausible staff figure at both ends. Growth through a merger or takeover counts. Temp and placement agencies (NACE 78) are left out: their staff counts the people they place with clients. We do not use turnover: the abridged schema does not carry it.
