Asia continues to represent a huge growth opportunity for Facebook.

Application developer Comdev found that from April 2009-April 2011, countries with the highest Facebook membership growth were from that region.

If Facebook were a country, it would be the fifth-largest nation in the Asia-Pacific, solely based on subscribers from countries in the region.

And that does not even take into account China, where access to the social network is restricted.

According to data from Comdev, Indonesia is the second-largest country in terms of Facebook membership, with some 35 million users, trailing only the U.S., at 154 million.

From April 2009 through April 2011, the growth rate of Facebook membership in Asia-Pacific countries was exponential:

  • Taiwan, 4,305 percent;
  • Thailand, 2,959 percent;
  • South Korea, 2,599 percent;
  • Philippines, 2,080 percent, and
  • Indonesia, 1,412 percent.

Of course, these figures need to be taken with a grain of salt, as the April 2009 figures are quite low, and two years is an eternity in Internet time.

However, Comdev points out that there are still ample expansion opportunities for the social network, as only 35 percent of Internet users in India have Facebook accounts, and that figure drops to 10 percent in South Korea. Expanded smartphone usage will likely help the cause, as well.

Comdev Chief Executive Officer Bryan Gan said:

When the majority of Internet users in your country are using Facebook at least once a day, you should consider promoting your business using the social-networking platform. With Facebook, you are able to gather your clients as fans to consistently build your brand awareness.

Readers, do you think the growth of Facebook membership in the Asia-Pacific region will continue to skyrocket, or level off?
