Going beyond traditionally used national and international input-output datasets, this paper presents a novel dataset and analyzes characteristics of actual global value chain (GVC) participating factories. Drawing from CSR reports of twenty multinationals identified using the Forbes 2000 list of publicly traded MNCs and covering over 10,000 supplying factories in the apparel, accessories, and footwear sectors, it develops summary statistics on supplier location, factory size, and employee gender distribution. The insights offered provide a description of participation in MNC supply chains by firm size, income level, and workforce gender composition―firm-level characteristics that are generally unavailable in official statistics and often accessible only behind paywalls of private information and analytics providers.
