Denominational Groups, Population, Countries, and Nuclear Capabilities

1. Introduction

Hinduism and Buddhism, with approximately 1.2 billion and 520 million adherents respectively, are two of the world’s major spiritual traditions, originating in South Asia and exerting significant cultural and geopolitical influence (Pew Research Center, 2015). This report compares Hinduism and Buddhism across four dimensions: (1) major denominational groups, (2) global population, (3) countries where each is the majority religion, and (4) nuclear capabilities of majority countries. The analysis aims to provide a comprehensive, evidence-based comparison, drawing on demographic and non-proliferation data to elucidate their global presence and strategic implications.

2. Methodology

  • Scope: Hindu-majority countries are those with >50% Hindu populations, and Buddhist-majority countries are those with >50% Buddhist populations, based on Pew Research Center (2015) and CIA World Factbook (2023). The analysis focuses on denominational groups, populations, countries, and nuclear capabilities, excluding other ideological or religious contexts.
  • Data Sources: Demographic data are sourced from Pew Research Center (2015) and CIA World Factbook (2023). Hindu denominations are informed by Flood (2020), and Buddhist denominations by Buswell and Lopez (2014). Nuclear capabilities are assessed using International Atomic Energy Agency (IAEA) (2024) and Arms Control Association (2025) reports.
  • Definitions:
  • Denominational Groups: Major traditions within Hinduism and Buddhism, based on theological, philosophical, or devotional distinctions.
  • Majority Countries: Nations where Hindus or Buddhists constitute >50% of the population.
  • Nuclear Capabilities: Confirmed nuclear weapons or civilian programmes with proliferation potential.
  • Analysis: Structured to compare denominational groups, population, countries, and nuclear status, ensuring a focused examination.

3. Comparative Analysis

3.1 Major Denominational Groups

  • Hinduism:
  • Vaishnavism: ~60–65% of Hindus (~720–780 million), focusing on worship of Vishnu and his avatars (e.g., Krishna, Rama), emphasizing devotion (bhakti) and texts like the Bhagavad Gita (Flood, 2020).
  • Shaivism: ~25–30% (~300–360 million), centred on Shiva as the supreme deity, with diverse practices from asceticism to devotion, drawing on texts like the Shiva Purana (Flood, 2020).
  • Shaktism: ~5–10% (~60–120 million), venerating the Divine Mother (e.g., Durga, Kali), prominent in regions like West Bengal (Flood, 2020).
  • Smartism: ~5% (~60 million), advocating non-sectarian worship of multiple deities as manifestations of Brahman, linked to Advaita Vedanta (Flood, 2020).
  • Other: <1% (~12 million), including syncretic movements (e.g., Arya Samaj) and folk traditions (Pew Research Center, 2015).
  • Total Groups: Four primary denominational traditions, with fluid boundaries due to Hinduism’s pluralistic nature.
  • Buddhism:
  • Theravada: ~38% of Buddhists (~200 million), emphasizing the Pali Canon and individual liberation through meditation, dominant in Southeast Asia (Buswell & Lopez, 2014).
  • Mahayana: ~56% (~290 million), focusing on compassion and the bodhisattva ideal, with schools like Zen and Pure Land, prevalent in East Asia (Buswell & Lopez, 2014).
  • Vajrayana: ~6% (~30 million), incorporating esoteric practices and tantric rituals, often a subset of Mahayana, prominent in the Himalayan region (Buswell & Lopez, 2014).
  • Other: <1% (~5 million), including modern movements (e.g., Nichiren, secular Buddhism) (Pew Research Center, 2015).
  • Total Groups: Three primary denominational traditions, with Mahayana encompassing diverse sub-schools.
  • Comparison: Hinduism has four major denominational groups, reflecting its devotional diversity, while Buddhism has three, with a clearer doctrinal structure. Hinduism’s traditions are more fluid, with practitioners often blending Vaishnavism and Shaivism, whereas Buddhist schools maintain distinct practices (e.g., Theravada’s monastic focus vs. Mahayana’s inclusivity).

3.2 Global Population

  • Hinduism: ~1.2 billion adherents, ~15% of the global population (Pew Research Center, 2015).
  • Breakdown: Vaishnavism (~720–780 million), Shaivism (~300–360 million), Shaktism (~60–120 million), Smartism (~60 million), Other (~12 million).
  • Trends: Steady growth projected through 2050, driven by high birth rates in South Asia, particularly India (Pew Research Center, 2015).
  • Buddhism: ~520 million adherents, ~7% of the global population (Pew Research Center, 2015).
  • Breakdown: Mahayana (~290 million), Theravada (~200 million), Vajrayana (~30 million), Other (~5 million).
  • Trends: Modest growth projected, primarily in Asia, with limited expansion in Western countries via conversion (Pew Research Center, 2015).
  • Comparison: Hinduism’s population (~1.2 billion) is more than double Buddhism’s (~520 million), reflecting its concentration in India. Both are predominantly Asian, but Hinduism is more demographically centralized, while Buddhism is spread across East and Southeast Asia.

3.3 Majority Countries

  • Hindu-Majority Countries (3 countries, South Asia/Indian Ocean):
  • India: ~79% Hindu (~1.1 billion), with Vaishnavism and Shaivism dominant, alongside Shaktism and Smartism (CIA World Factbook, 2023).
  • Nepal: ~81% Hindu (~24 million), primarily Vaishnavism and Shaivism, with Shaktism influences (e.g., goddess worship) (CIA World Factbook, 2023).
  • Mauritius: ~52% Hindu (~650,000), mainly Vaishnavism and Shaivism, reflecting Indian diaspora heritage (CIA World Factbook, 2023).
  • Buddhist-Majority Countries (7 countries, Asia):
  • Thailand: ~93% Buddhist (~65 million), predominantly Theravada (CIA World Factbook, 2023).
  • Myanmar: ~88% Buddhist (~48 million), predominantly Theravada (CIA World Factbook, 2023).
  • Sri Lanka: ~70% Buddhist (~16 million), predominantly Theravada (CIA World Factbook, 2023).
  • Cambodia: ~97% Buddhist (~16 million), predominantly Theravada (CIA World Factbook, 2023).
  • Laos: ~66% Buddhist (~5 million), predominantly Theravada (CIA World Factbook, 2023).
  • Bhutan: ~75% Buddhist (~600,000), predominantly Vajrayana (Drukpa Kagyu) (CIA World Factbook, 2023).
  • Mongolia: ~53% Buddhist (~1.7 million), predominantly Vajrayana (Tibetan Buddhism) (CIA World Factbook, 2023).
  • Comparison: Buddhism predominates in more countries (7 vs. 3), reflecting its historical spread across Southeast Asia and the Himalayan region. Hinduism is concentrated in fewer countries, with India dominating due to its population size. Both are exclusively Asian, but Buddhism’s geographical spread is broader.

3.4 Nuclear Capabilities

  • Hindu-Majority Countries:
  • India (~79% Hindu):
    • Nuclear Arsenal: ~172 warheads, non-NPT signatory, declared nuclear state since 1998 (Arms Control Association, 2025).
    • Delivery Systems: Ballistic missiles (e.g., Agni-V), aircraft, submarine-based capabilities (e.g., INS Arihant).
    • Civilian Programme: 22 reactors, partial IAEA safeguards due to non-NPT status (IAEA, 2024).
  • Nepal: No nuclear weapons or programme, NPT signatory, compliant with IAEA safeguards (IAEA, 2024).
  • Mauritius: No nuclear weapons or programme, NPT signatory, compliant with IAEA safeguards (IAEA, 2024).
  • Buddhist-Majority Countries:
  • Thailand, Myanmar, Sri Lanka, Cambodia, Laos, Bhutan, Mongolia: No nuclear weapons or programmes, all NPT signatories, compliant with IAEA safeguards. Thailand and Sri Lanka operate research reactors for peaceful purposes (e.g., medical isotopes) (IAEA, 2024). Mongolia has a UN-recognized nuclear-weapon-free status since 1992 (Arms Control Association, 2025).
  • Comparison: Only one Hindu-majority country (India, ~172 warheads) possesses nuclear capabilities, while no Buddhist-majority country has nuclear weapons or proliferation programmes. India’s nuclear status reflects its geopolitical ambitions, whereas Buddhist-majority countries’ non-nuclear stance aligns with their limited military-industrial capacities or deliberate non-militarization (e.g., Bhutan, Mongolia).

4. Discussion

Hinduism’s four denominational groups (Vaishnavism, Shaivism, Shaktism, Smartism) contrast with Buddhism’s three (Theravada, Mahayana, Vajrayana), with Hinduism’s traditions being more devotionally diverse and fluid, while Buddhism’s are doctrinally distinct. Hinduism’s larger population (~1.2 billion vs. ~520 million) is concentrated in India, giving it demographic weight, whereas Buddhism’s broader spread across seven countries reflects its historical diffusion. India’s nuclear capabilities (~172 warheads) make it a significant power, while Buddhist-majority countries’ lack of nuclear programmes underscores their focus on regional stability or non-militarization (Flood, 2020; Buswell & Lopez, 2014). Geopolitical factors, not denominational identity, drive nuclear policy. Social media claims (e.g., on X) about demographics or nuclear activities should be verified due to misinformation risks.

5. Conclusion

Hinduism, with ~1.2 billion adherents and four denominational groups, predominates in three countries (India, Nepal, Mauritius), with India possessing ~172 nuclear warheads. Buddhism, with ~520 million adherents and three denominational groups, predominates in seven countries (Thailand, Myanmar, Sri Lanka, Cambodia, Laos, Bhutan, Mongolia), none of which have nuclear capabilities. Future research could explore the cultural influence of Hindu versus Buddhist traditions on national identity or their roles in regional geopolitics.
