S&P 500 companies are continuing to make strides in board diversity. Through May 2021, S&P 500 boards designated 456 new independent directors, the largest addition since 2004. Seventy-nine percent of that number are minority men and women, according to a new report by Spencer Stuart, an executive search and leadership advisory firm.

In addition to this, 30% of all S&P 500 directors are women, showcasing continuous improvement since last year's study.
