The technology industry is still failing to tackle its diversity crisis, according to data released by an independent network of over 3,600 tech experts.

Almost half of London's technology companies (46%) do not believe a diverse workforce improves company growth, according to the report by Tech London Advocates.

"We need to face up to the fact that we have a serious issue with diversity in the technology industry," said Maggie Philbin, CEO of Teen Tech.

"Social background, gender and disability continues to trip up talent.

"By opening the right doors to help young people and the industry understand both the opportunities and the potential we can equip everyone to become a part of the tech revolution, not just the fortunate few."


Gender representation amongst technology companies in the capital is also unbalanced. Out of 40,000 firms based in London nearly 1,000 have an entirely male workforce, the report estimated.

The survey also reveals more than one in three technology companies employ a majority of their staff from outside London.

"Diversity has been an ongoing challenge for the tech sector, however the business case for diversity is stronger now than ever," said Aftab Malhotra, founder of GrowthEnabler.

"The future growth for tech will come from emerging markets like India and China, and we need a diverse and digitally enabled workforce and a set of strong tech leaders to compete, collaborate and trade relations with these countries."

Employers are being encouraged to create an inclusive company from the top down and celebrate difference, through demanding diversity and inclusivity in all recruitment strategies.
