The non-official number of ethnic believers is up to 20 million. The government often views indigenous beliefs as "kepercayaan adat" (custom) rather than "agama" (religion) or as a variant of a recognised religion. Because of this, followers of these beliefs such as Dayak Kaharingan have identified themselves as Hindu as a result to avoid pressure to convert to Islam or Christianity. Several native tribal beliefs such as Sunda Wiwitan, Toraja Aluk Todolo, and Batak Parmalim — although different from Indian-influenced Balinese Hinduism — might seek affiliation with Hinduism to survive, while at the same time also preserving their distinction from mainstream Indonesian Hinduism dominated by the Balinese. In many cases, some of the followers of these native beliefs might convert to Christianity or Islam, at least registered as such on their KTP while still upholding and performing their native beliefs.
