More successful companies tend to have a larger proportion of women in senior management roles, new research by McKinsey has found. Between 2011 and 2015, the most gender diverse quarter of companies were 21 percent more likely than the least diverse to have above average financial performance. Australian companies lead the way when it comes to women’s share of executive roles (21 percent). The share in the United States is 19 percent and in the United Kingdom is 15 percent. The report, Delivering through Diversity, also found correlation between ethnic diversity and financial performance, particularly in the UK. Globally, those companies with a low proportion of both female and ethnic minority executives were 29 percent more likely to financially underperform than their peers.
