Religions in India in 2025: Complete List With Population Percentages

“Across the world, India is recognized for the remarkable variety of religions and spiritual traditions followed by its people.” With a population exceeding 1.4 billion people in 2025, the country is home to almost every major world religion as well as several faiths that originated on the Indian subcontinent itself. The Indian Constitution guarantees freedom of religion, allowing multiple belief systems to coexist within a single national framework.

This article provides a clear, updated overview of religions in India in 2025, including estimated population percentages, historical background, and social influence. 

Religious Landscape of India in 2025 (Overview)

India does not conduct a full religious census every year. Therefore, religious distribution in 2025 is best understood through demographic continuity, fertility trends, migration patterns, and long-term population studies. While small changes occur annually, the overall structure of India’s religious composition remains relatively stable.

Estimated Religious Composition of India in 2025

Religion Estimated Percentage (2025)
Hinduism ~79%
Islam ~15%
Christianity ~2.3%
Sikhism ~1.7%
Buddhism ~0.7%
Jainism ~0.4%
Other religions ~0.7%
No religion / Not stated ~0.2%

These estimates reflect gradual demographic change rather than sudden shifts

Hinduism in India (≈ 79%)

The Largest Religion in the Country

Hinduism remains the dominant religion in India in 2025, followed by roughly four out of five Indians. It is also the world’s oldest continuously practiced religious tradition, with roots stretching back thousands of years.

Key Characteristics

  • No single founder

  • Philosophical diversity (Vedanta, Yoga, Bhakti, Shaivism, Vaishnavism)

  • Its spiritual literature is rooted in ancient writings such as the Vedas and Upanishads, along with legendary narratives including the Mahabharata.

Social and Cultural Influence

Hindu traditions strongly shape Indian festivals, daily rituals, family structures, and national holidays. Major celebrations such as Diwali, Holi, Navratri, and Raksha Bandhan are observed far beyond strictly religious contexts.

Despite a slight proportional decline over decades, Hinduism’s absolute population continues to grow due to India’s overall population increase
