Women in the Workplace is the largest study on the state of women in corporate America. In 2015, LeanIn.Org and McKinsey & Company launched the study to give companies insights and tools to advance gender diversity in the workplace. Between 2015 and 2021, over 750 companies participated in the study, and more than a quarter of a million people were surveyed on their workplace experiences. This year, information was collected from 423 participating organizations employing 12 million people, surveyed more than 65,000 employees, and conducted interviews with women of diverse identities, including women of color, LGBTQ+ women, and women with disabilities. 2021 findings focus on the impact of the COVID-19 pandemic and the growing emphasis on diversity, equity, and inclusion on the experiences of women and the state of work more broadly.
