In this month’s language stats, we’re focusing in on Indonesia, which recently became Facebook’s third-largest country by monthly active users and is poised to pass the United Kingdom for second place. Because it’s growing quickly, Indonesia’s importance for marketers and localization of apps is quickly rising.

We recently looked at country-by-country language data on Facebook. While each country with a presence on Facebook tends to have its own primary language, it’s also common for countries to have a number of less significant, secondary languages in use. In the United States; for instance, between one and two percent of users, totaling over 1.6 million users, access Facebook in Spanish.

Beyond the US, the shares of secondary languages quickly become much larger, with English usually remaining a significant presence.

In particular, language demographics become rather complicated in Asia, where users often choose to surf the web in English. That’s certainly true for Indonesia’s Facebook audience:

Although English usage fell over the month from 21.7% to 21.34% of Indonesia users, that’s still a huge chunk, much larger than we’d typically see for a secondary language in Europe. For example, English is only used by 5.2 percent in France, Facebook’s fifth-largest country.

But it turns out that Indonesians are cultural stalwarts in comparison to others in their region. Here’s how Indonesia’s percentage of Facebook users who load the site in English compared to four neighbors:

This data is not perfect; for instance, we can’t tell whether users are choosing to interact with Facebook in English, but communicate with their friends and family in their native language. This could be a habit developed while using the mainly English-language internet over the years, and simply preserved on Facebook.

However, there are a few more things we can tell about this large population of English users. Here’s how they break down by age, just in Indonesia:

These splits between age groups tend to reflect Indonesia’s predominantly youthful audience. However, there’s an interesting phenomenon to pick out: it’s actually Indonesia’s older users who are more likely to use the site in English. Up to the age of 25, some 17 percent of Indonesians are using Facebook in English, while 30 percent of those over 25 use the site in English. The likelihood of using English increases as the age group gets younger or older.

For a country like the Philippines, in which almost all users are already accessing Facebook in English, it is difficult to get a clear picture of how language demographics are changing, if at all. Indonesia’s stats, though, suggest that the Asian audience will likely move to using their own languages over time as more young users join the site.
