Seattle-based research firm PayScale said Facebook employees are the most satisfied and the Mark Zuckerberg-led company had the lowest median age - 26.
It also had the highest portion of female workers at 33 per cent, among nine of the industry's top businesses.
A typical worker at Facebook is only 26 years of age, compared with a typical age of 36 across the other companies.
Workers at Facebook are the most satisfied with their jobs, while those at Hewlett-Packard are the least satisfied.
The report said while Facebook employees may be the most satisfied with their work, they are also some of the most stressed.
"With a CEO who is 27, it is not surprising to find many who work at Facebook are young, excited to work there and a little stressed out," said Al Lee, director of quantitative analysis at PayScale.
The report said median pay for Google employees is 23 per cent higher than similar workers performing similar roles at other companies.
