Demographic Profile of India

The Demographic Profile of India is a critical socio-biological chapter in WBCS Anthropology Paper 2 (Unit 4). It combines demographic principles, statistical rates and ratios, population dynamics across rural, urban, and tribal sectors, and linguistic classifications of the Indian population.

This study note provides complete coverage for all 3 sub-units:

• 4.1 Demography: Concept, theories, and methods.
• 4.2 Structure and features of Indian population; Rates and Ratios (Fertility, Mortality; Factors influencing fertility and mortality); Dynamics of demography in rural, urban, and tribal contexts; Migration and effects of migration.
• 4.3 Linguistic elements in Indian population (G.A. Grierson and S.K. Chatterjee).

4.1 Demography: Concepts, Theories, and Methods

#

1. Concept of Demography

#

Etymologically derived from Greek Demos (people) and Graphrein (to write/describe), Demography is the scientific and statistical study of human populations.

In Anthropology, Demographic Anthropology / Anthropological Demography integrates quantitative demographic techniques with qualitative ethnographic methods to understand how culture, kinship, marriage, ecology, and biology shape population processes (fertility, mortality, and migration).

A. Malthusian Theory of Population (1798)

#

• Core Thesis: Population increases in a Geometric Progression (1, 2, 4, 8, 16, 32…), whereas food supply increases in an Arithmetic Progression (1, 2, 3, 4, 5…).
• Checks on Population:
  • Preventive Checks: Moral restraint, late marriage, celibacy.
  • Positive Checks: Famine, disease, war, epidemics (“Malthusian Catastrophe”).
• Anthropological Critique: Malthus ignored technological progress in agriculture (Green Revolution) and socio-cultural fertility controls.

B. Demographic Transition Theory

#

Explains the historical transformation of population dynamics alongside economic modernization through 4 main stages:

    B --> C[Stage 3\nBirth rate falls]
    C --> D[Stage 4\nLow birth and death rates]
    B -. India: 1921-1981 .-> C
    C -. Modern India .-> D

 Stage 1: High Stationary   --> Stage 2: Early Expanding   --> Stage 3: Late Expanding   --> Stage 4: Low Stationary
 (High CBR, High CDR)           (High CBR, Falling CDR)         (Falling CBR, Low CDR)        (Low CBR, Low CDR)
 [Pre-industrial India]         [India: 1921–1981]              [Modern India]               [Developed Nations]

1. Stage 1 (High Stationary): High Crude Birth Rate (CBR) and High Crude Death Rate (CDR). Stable/slow growth (Pre-industrial societies).
2. Stage 2 (Early Expanding): High CBR, but rapidly declining CDR due to healthcare and sanitation improvements. Population Explosion (India between 1921 and 1981).
3. Stage 3 (Late Expanding): Falling CBR alongside low CDR. Population growth slows down (Modern India’s current phase).
4. Stage 4 (Low Stationary): Low CBR and Low CDR. Population stabilizes (Western Europe, Japan).

3. Demographic Methods and Data Sources

#

1. Census: Direct complete enumeration of population at regular intervals (Decennial Census in India since 1872/1881).
2. Sample Registration System (SRS): Dual-record system providing annual estimates of fertility and mortality rates in India.
3. National Family Health Survey (NFHS): Large-scale multi-round survey providing reliable data on fertility, infant mortality, maternal health, and nutrition (NFHS-5: 2019–21).
4. Vital Registration System (VRS): Civil registration of births and deaths.

4.2 Structure and Features of Indian Population, Rates, Ratios, and Dynamics

#

1. Age-Sex Structure and Population Pyramid of India

#

    A[0-14 years\nBroad base] --> B[15-59 years\nLarge working-age population]
    B --> C[60+ years\nNarrower apex]
    D[Demographic dividend] --- B

• Broad-Based Pyramid: India possesses a relatively young population structure (demographic dividend median age ~28 years), transitioning from a expansive pyramid to a stationary shape.
• Sex Ratio: Defined in India as the number of females per 1,000 males.
  • Census 2011: 940 females per 1,000 males.
  • NFHS-5 (2019-21): 1,020 females per 1,000 males (sample survey estimate).
  • Child Sex Ratio (0–6 years): Severely distorted (918 females per 1,000 males in Census 2011), reflecting female foeticide, son preference, and patriarchal social norms.

2. Fertility Rates and Influencing Factors

#

Key Rates & Ratios:

#

• Crude Birth Rate (CBR):
  $$\text{CBR} = \frac{\text{Total Live Births in a year}}{\text{Mid-year Total Population}} \times 1000$$
• General Fertility Rate (GFR):
  $$\text{GFR} = \frac{\text{Total Live Births}}{\text{Mid-year Female Population aged 15–49}} \times 1000$$
• Total Fertility Rate (TFR): The average number of children a woman would bear in her lifetime.
  • Replacement Level TFR: 2.1
  • India’s Current TFR (NFHS-5): 2.0 (below replacement level for the first time).

Factors Influencing Fertility in India:

#

1. Socio-Cultural Factors:
   • Universal and early marriage age.
   • Son preference (Vamsha continuity, performance of funeral rites, old-age security).
   • Joint family system providing shared child-rearing support.
2. Economic Factors: Children viewed as economic assets / labor in agrarian and tribal economies.
3. Educational & Women’s Autonomy: Female literacy shows a direct inverse correlation with TFR (e.g., Kerala TFR ~ 1.7 vs. Bihar TFR ~ 2.9).
4. Contraceptive Prevalence: Usage of modern family planning methods.

3. Mortality Rates and Influencing Factors

#

Key Rates & Ratios:

#

• Crude Death Rate (CDR):
  $$\text{CDR} = \frac{\text{Total Deaths in a year}}{\text{Mid-year Total Population}} \times 1000$$
• Infant Mortality Rate (IMR):
  $$\text{IMR} = \frac{\text{Deaths of infants under 1 year of age}}{\text{Total Live Births in that year}} \times 1000$$(India NFHS-5: ~35 per 1,000).
• Maternal Mortality Ratio (MMR): Maternal deaths per 100,000 live births (India SRS 2018–20: 97 per 100,000).
• Life Expectancy at Birth: Average expected lifespan (India current: ~70 years).

Factors Influencing Mortality in India:

#

1. Biological & Nutritional Status: High prevalence of malnutrition, stunting, wasting, and maternal anemia.
2. Healthcare Infrastructure: Availability of institutional deliveries, immunization coverage, and rural primary healthcare (PHCs).
3. Sanitation and Clean Drinking Water: Prevention of water-borne infectious diseases (diarrhea, cholera).
4. Epidemiological Transition: Double burden of communicable diseases (tuberculosis, malaria) and non-communicable diseases (cardiovascular, diabetes).

4. Demographic Dynamics in Rural, Urban, and Tribal Contexts

└─────────────────┴──────────────────────┴────────────────────────┴──────────────────────┘

A. Rural Demographic Context

#

• Higher dependence on agriculture, higher CBR, and larger family size.
• Seasonal out-migration of young males to urban centers leading to the “feminization of agriculture” and skewed rural sex ratios.

B. Urban Demographic Context

#

• Lower TFR below replacement level due to high cost of living, nuclear family structures, late marriages, and working women.
• Concentration of migration in slums characterized by overcrowding, sanitation deficits, and informal labor.

C. Tribal Demographic Context

#

• High Vulnerability: Higher IMR, MMR, and lower life expectancy due to geographical isolation and poor healthcare access.
• Particularly Vulnerable Tribal Groups (PVTGs): 75 recognized PVTGs (e.g., Onge, Sentinelese, Great Andamanese, Birhor) exhibit stagnant or declining population numbers due to genetic isolation, high infant mortality, malnutrition, and endemic diseases (e.g., sickle-cell anemia, malaria).

5. Migration and Effects of Migration

#

Migration involves the movement of people across spatial/administrative boundaries involving a change of usual place of residence.

Types of Migration:

#

• Internal Migration: Rural-to-Rural (dominated by marriage migration among females), Rural-to-Urban (economic/labor migration dominated by males), Urban-to-Urban, Urban-to-Rural.
• International Migration: Out-migration to Gulf countries, Western nations.

Push and Pull Factors:

#

• Push Factors (Origin): Poverty, rural unemployment, land alienation, environmental disasters, caste oppression.
• Pull Factors (Destination): Employment opportunities, higher wages, modern educational and medical infrastructure.

    B -->|Pull: jobs, wages, education| C[Urban destination]
    C --> D[Remittances]
    D --> A
    C --> E[Pressure on housing and services]

Effects / Consequences of Migration:

#

1. Demographic Effects: Alteration of age-sex pyramids at both origin (depleted working-age males) and destination (skewed male-dominated urban sex ratio).
2. Socio-Economic Effects:
   • Remittances: Financial flow from urban migrants back to rural families boosting rural consumption.
   • Urban Slums: Proliferation of unorganized informal settlements and strain on civic infrastructure.
3. Cultural Effects (Acculturation): Exposure to diverse cultural practices, erosion of traditional caste barriers in urban spaces.

4.3 Linguistic Elements in Indian Population

#

India is a polyglot nation comprising hundreds of languages and dialects. The linguistic classification of Indian populations relies heavily on two pioneering scholars: Sir George Abraham Grierson and Suniti Kumar Chatterji.

1. Sir George A. Grierson’s Classification

#

Sir George Grierson directed the monumental Linguistic Survey of India (LSI) (published between 1903 and 1928 in 11 volumes), identifying 179 languages and 544 dialects.

Grierson’s Classification Scheme:

#

Grierson grouped Indian languages into 5 Major Language Families:

1. Indo-Aryan Sub-Family (of Indo-European):
   • Outer Branch: Northwestern group (Lahnda, Sindhi), Southern group (Marathi), Eastern group (Odia, Bengali, Assamese).
   • Mediate Branch: Central group (Eastern Hindi - Awadhi, Bagheli).
   • Inner Branch: Western Hindi, Punjabi, Gujarati, Rajasthani, Pahari.
2. Dravidian Family:
   • Southern Group: Tamil, Malayalam, Kannada.
   • Central Group: Telugu, Kui, Gondi, Khond.
   • Northern Group: Kurukh (Oraon), Malto, Brahui (spoken in Balochistan, Pakistan).
3. Austro-Asiatic Family:
   • Munda Sub-Family: Santhali, Mundari, Ho, Korku, Kharia (spoken by Central Indian tribes).
   • Mon-Khmer Sub-Family: Khasi (Meghalaya) and Nicobarese.
4. Tibeto-Chinese Family (Sino-Tibetan):
   • Tibeto-Burman Sub-Family: Bodo, Naga, Kuki-Chin, Manipuri, Abor-Miri, Ladakhi.
   • Siamese-Chinese Sub-Family: Khamti (Arunachal Pradesh).
5. Karen and Unclassified Languages: Isolated speeches of Andamanese.

2. Dr. Suniti Kumar Chatterji’s Classification

#

Dr. Suniti Kumar Chatterji, India’s foremost philologist and author of The Origin and Development of the Bengali Language (ODBL), revised Grierson’s framework by integrating historical-comparative linguistics and racial-cultural synthesis.

Key Features of S.K. Chatterji’s Classification:

#

1. Synthesis of Language and Culture: Chatterji emphasized that the Indian population represents a linguistic and cultural convergence area (Linguistic Area / Sprachbund), where distinct language families borrowed syntax, phonetics, and vocabulary from one another.
2. Four Great Language-Culture Substrata:
   • Nishada (Austro-Asiatic / Munda): Represented by the earliest tribal population; contributed words related to agriculture (e.g., banana, betel, coconut), flora, and fauna into Sanskrit.
   • Dravida (Dravidian): Pre-Aryan urban civilization substratum; introduced retroflex consonants ($ṭ, ḍ, ṇ$) and vocabulary into Indo-Aryan languages.
   • Arya (Indo-Aryan): Introduced the Vedic Sanskrit structure, expanding into Middle Indo-Aryan (Prakrit/Pali) and New Indo-Aryan (Modern languages).
   • Kirata (Sino-Tibetan / Tibeto-Burman): Spoken by Mongoloid groups in the Himalayan and North-Eastern regions.
