Context:

• India’s social and cultural landscape is marked by extraordinary diversity, reflected in its caste communities, Denotified and Nomadic Tribes (DNTs), and languages.
• Yet, paradoxically, the country lacks precise data on several of these categories. Historical processes, colonial classifications, and post-Independence administrative choices have left significant gaps in understanding India’s social composition.
• With the delayed Census (originally scheduled for 2021, now expected to conclude by 2027), questions regarding the enumeration of Other Backward Classes (OBCs), DNTs, and languages remain contentious and unresolved.

India’s Caste Communities - An Uncertain Count:

• Evolution of caste communities:
  • The number of caste communities in India remains uncertain despite extensive anthropological and historical research.
  • Various theories attribute the emergence of caste to -
    • Occupational specialisation
    • Ritual hierarchy and social stratification
    • Tribal integration into the caste system
    • Regional socio-economic transformations
  • However, no consensus exists regarding the exact number or origin of caste communities.
• Other Backward Classes (OBCs):
  • India also lacks a precise count of OBC communities.
  • The Mandal Commission (1980) identified thousands of socially and educationally backward groups, but enumeration has never been systematically updated.
  • Absence of caste-based Census data limits accurate assessment of their demographic and socio-economic status.

Denotified and Nomadic Tribes (DNTs) - A Neglected Category:

• Historical background:
  • Many nomadic communities were classified as “Criminal Tribes” under the Criminal Tribes Act (CTA), 1871, by the British colonial government.
  • These communities were subjected to systematic surveillance and restrictions on movement.
• Denotification and present status:
  • The Criminal Tribes Act was repealed in 1952, leading to the “denotification” of these groups.
  • After Independence, they were placed under Scheduled Castes (SC), Scheduled Tribes (ST), OBCs, or the General category, depending on regional classification.
• Data deficit: India still does not have an official count of DNT communities or their population. This represents a major gap in policy formulation for historically marginalised groups.

Language Diversity in India:

• Early linguistic survey:
  • The first comprehensive attempt to map India’s linguistic diversity was the Linguistic Survey of India, proposed by George Abraham Grierson in 1886.
  • Conducted over three decades, it documented 179 languages, and 544 dialects.
• Post-independence developments:
  • Despite India being organised into linguistic states, there has been no independent linguistic survey since independence. Instead, language data is derived from the Census.
  • Census language data:
    • 1961 Census: 1,652 mother tongues
    • 1971 Census: 108 languages (plus “others”)
    • 2011 Census: 1,369 mother tongues and 121 languages
  • This shows the disappearance of 283 mother tongues between 1961 and 2011, raising questions about classification methods and data processing.

Issues with Census Language Classification:

• Arbitrary criteria:
  • Census reports often exclude languages spoken by fewer than 10,000 people.
  • Linguistically, this criterion has no scientific basis, as language identity is not determined by the number of speakers.
• Mother tongue vs language:
  • The Census distinction between “mother tongue” and “language” is widely criticised as methodologically inconsistent.
  • Such classifications risk undermining India’s linguistic diversity.

Recent Debates on Language Origins:

• Linguistic families in India: Scholars generally classify Indian languages into four major families Indo-Aryan, Dravidian, Sino-Tibetan, and Austro-Asiatic.
• The “Bharat Bhasha Parivar” idea:
  • The Bharatiya Bhasha Samiti has proposed that all Indian languages belong to a single linguistic family (“Bharat Bhasha Parivar”), with Sanskrit as the primordial source predating the Indus Valley Civilisation.
  • Linguists argue that this view lacks scientific or comparative linguistic evidence, and is more ideological than scholarly.

Key Challenges and Way Forward:

• Absence of comprehensive social enumeration: No accurate count of caste communities, OBCs, or DNTs.
  • Conduct caste and community-based data collection, including OBCs and DNTs, to enable evidence-based policymaking.
• Data gaps in linguistic diversity: Lack of a post-Independence Linguistic Survey of India.
  • Revive the Linguistic Survey of India - Undertake a modern linguistic survey using digital and field-based methodologies.
• Methodological flaws in Census data: Arbitrary thresholds for language recognition, confusing distinction between mother tongue and language.
  • Scientific census methodology - Remove arbitrary thresholds for language recognition. Adopt internationally accepted linguistic classification standards.
• Policy implications: Inadequate data affects welfare policies, representation, and social justice measures.
  • Focused policy for DNTs - Prepare an official registry and socio-economic survey of Denotified and Nomadic Tribes to address historical marginalisation.
• Politicisation of linguistic history: Attempts to homogenise linguistic origins risk ignoring established linguistic scholarship.
  • Evidence-based linguistic research - Encourage independent academic research free from ideological influence.

Conclusion:

• India’s remarkable diversity—social, cultural, and linguistic—remains only partially understood due to incomplete data and methodological limitations in enumeration exercises.
• Without accurate mapping of caste groups, DNTs, and languages, policymaking risks being detached from ground realities.
• A scientific, transparent, and inclusive census and linguistic survey is essential to understand the true contours of Indian society and to strengthen democratic governance, social justice, and cultural preservation.
