Tech is one of the toughest glass ceilings for women to break through: Women held just 25% of professional computing occupations in 2015, according to the National Center for Women & Information Technology–down from a high of 36% in 1991.

Further, tech’s gender pay gap is also worse than the US national average, according to a Glassdoor report, with women in the field earning on average $0.94 for every $1.00 men earn.

However, progress is being made in many companies. Comparably, a compensation and job reviewing site, examined its database of thousands of salaries, job titles, and employee ratings and reviews shared in the past year to determine which companies and cities offer the best cultural fit and compensation for women in the tech industry.

The top cities for women working in tech based on jobs and highest median salaries were San Francisco, Los Angeles, New York, Seattle, Austin, Boston, Chicago, Dallas, and Washington, DC.
