Whether young Indonesians are more religious than their parents is a poorly aimed question. The data from 2023 to 2026 shows that what is happening is not simply an increase or decrease in religiosity, but a transformation in the form of religious life.
Indonesia's Gen Z leads on religious identity and values, so they are subjectively religious and consistent in global surveys. They also lead on Qur'anic literacy and interfaith tolerance, both rising and highest across generations. Conversely, they are weak on daily ritual practice, as confirmed by the Ministry in 2023, 2024, and the 2025 IKM/IKS surveys. As for conservatism, their position is ambiguous because their ideological views are strict, but this does not automatically correlate with ritual diligence.
A more accurate understanding is that the religiosity of Indonesia's Gen Z is expressive and selective. They express their faith through identity, views, and digital media, but do not always internalize it as a daily worship routine. This pattern is also found among young Muslims in other global contexts, and it poses a distinct challenge for formal religious institutions that have long defined religiosity primarily through ritual parameters.
What is striking is that over the past three years (2023 to 2025), all of Indonesia's religious harmony and tolerance indices have continued to rise, with Gen Z at the forefront. Perhaps that is this generation's greatest contribution to Indonesia's religious life: not its ritual diligence, but its openness and tolerance.
