100 Best Workplaces for Women 2017

See our methodology and credits



To determine the Best Workplaces for Women, Great Place to Work surveyed over 400,000 U.S. employees from Great Place to Work-Certified companies and ranked companies based on four factors:

Key Great Place to Work Metrics. We analyzed how positively women rated their organizations on over 50 different metrics defining great workplaces, including ethical leadership, respectful and fair workplace interactions, great benefits and development, and strong caring and personal support.

Comparison to Colleagues. We compared women's results on all survey questions to that of their male colleagues. Specifically, we looked at an index of factors where the data showed women often lag their peers, such access to leaders and information, and recognition for their work.

A Consistent Experience Within a Diverse Group. We analyzed demographic patterns to ensure that companies were creating great workplaces for all women, regardless of who they are or what they do for the organization.

Representation. We took into account how well women were represented in each organization—in the workforce as a whole, as well as in management and executive positions.

Surveys were conducted anonymously and women's results achieved at least a 95% confidence level, 7% margin of error for each organization. Companies needed to employ at least 50 women to be considered.

In recent years, U.S. companies have made big strides in creating office cultures that cater to the female half of their workforce. Flexibility, paid leave, and no harassment are just the beginning, though. For our annual list of the 100 Best Workplaces for Women, Fortune partner Great Place to Work surveyed thousands of women at companies across the country and crunched the numbers to create this list of workplaces that go above and beyond for their female employees.

Zillow Group

Employees say: “On numerous occasions, when I’ve had a question or a problem I need to solve, I go to ask an expert at the company about it; they work with me until we solve it, regardless of the time it takes or how closely it relates to the scope of their work. To me, this is a great example of the ‘ZG is a Team Sport’ mentality that pervades the culture here.”


“Zillow Group is unusually invested in the development of its employees. Our Learning and Development team puts together a full schedule of lunches and lectures on a variety of business-related topics and works hard to bring in amazing outside speakers (like author Brad Stone), who talk about business in general.” Read the Great Place to Work review.
