The study, based on employment data shared by Google, Intel, LinkedIn, Hewlett-Packard and Yahoo, said Asians were found to be 27.2 per cent of the professional workforce.
However, only 13.9 per cent of executives in the professional workforce at Google, Hewlett-Packard, Intel, LinkedIn, and Yahoo were Asians.
"Asian" includes any citizen or non-citizen having origins in any of the original peoples of the Far East, Southeast Asia or the Indian Subcontinent.

Google and LinkedIn did not comment on the report.
The report found that although there are nearly as many Asian professionals as white professionals in most of these five companies, white men and women are about 154 per cent more likely to be an executive compared to their Asian counterparts.
Ascend identified three major Asian leadership gaps: a gap in awareness and expectations, a gap in role models, and a gap in behaviour.
"Although awareness and behavioural gaps are not unique to the Asian community, social science research and our personal observations find that traditional upbringing and cultural norms can hinder many in bridging those gaps.
"Social science research suggests that an Asian effect is rooted in a cultural mismatch between Asian and western leadership norms which feed the western implicit stereotype that Asians have poor leadership skills," it said.
