This paper explores the metrics that companies can use to measure the experience of women in the workplace more consistently. We take stock of the current state of measurement by evaluating the current parties involved in reporting: Governments, ESG Ratings Providers, Accounting and Disclosure Framework Boards, and Exchanges. We then present a robust suite of metrics that companies should strive to collect and report. This set of metrics, Four for Women, buckets metrics into Representation, Pay, Health, and Satisfaction and comes from Wharton’s Social Impact Initiative.
