you probably meant indonesian right? there are not that many indians living in indonesia (compared to, say, singapore).
Singapore and Malaysia are having sizable Indian minorities because Tamil laborers were imported to those counties during the British colonial rule. Indonesia was under the Dutch colonial rule and there was no need for importing laborers from elsewhere. Even then, you can find small Tamil minorities in cities such as Medan and Jakarta.
i see, that makes sense. in the cities that i live in (jakarta, bandung, other places in java) there are not that many. most are in the textile business (a few elite ones are in the media producing business).
