The latest research from KPMG’s Board Leadership Centre surveyed 64 FTSE 350 board members and found that over 70% of respondents came from high socio-economic (professional) backgrounds, while only 15% came from low socio-economic backgrounds – suggesting a lack of socio-economic diversity in boardrooms.

More than a quarter (28%) attended a private school, suggesting an over-representation of privately educated board members when private schools account for just 7% of the UK’s pupil population today.

Respondents also highlighted the importance of networks and mentors in reaching the highest levels of business, with 67% stating they benefited from access to both.
