"The overall disparities in the number of female art museum directors and in their salaries are mostly driven by the largest museums. These museums have operating budgets of more than $15 million and represent roughly the top quarter of AAMD member museums by operating budget. At these largest museums, female directors earn 71 cents on average for every dollar earned by male directors."
