Methodology

The observed profile metric and trend chart use the same latest available monthly snapshot, with its observation month shown separately from the page update date. Company-reported workforce totals appear only when supported by a primary source and remain separate from profile counts. Geographic distributions use a separate current profile population and person location fields, never company headquarters. Country counts describe countries represented in those profiles, not offices. Location percentages include profiles without a known city or region in their denominator. Department, seniority, and title coverage may differ from the company workforce.
