Age Diversity Within Boards of Directors of the S&P 500 Companies

This study examines age diversity within the boards of the companies in the S&P 500. At a time when board refreshment of public companies and director diversity, or lack thereof, is a key concern of companies, investors and others, the dispersion of age within the board has largely been ignored. Therefore, this analysis examines the age diversity of boards with analyses by industry, company size (market capitalization), and company age (years since the company’s initial public offering). We also consider the number of age groups (de ned by decades) represented on each board.
