Washington, Friday, February 3, 2012: Popular social networking site Facebook finds India a major growth market, where the number of users have more than doubled in the past one year, as against near-zero penetration in the neighbouring China.

For Facebook, looking to raise $5 billion through initial share sale, India is a key source for future growth.

The growth of 132 per cent in India has been higher than many other countries, including home market in US.

“We have achieved varying levels of penetration within the population of Internet users in different countries,” Facebook has said, while noting that its penetration rate in India was estimated to be 20-30 per cent.
