WBCS Main Census & Demography Questions and Answers

Answer: (B) Pastoralism

Explanation: The Toda tribe, an indigenous ethnic group inhabiting the Nilgiri hills of Tamil Nadu in southern India, has traditionally practiced pastoralism as their main occupation, centered around the herding and rearing of buffaloes. The Todas are particularly known for their unique buffalo-centered pastoral economy and culture, where dairy products, especially buffalo milk and ghee, hold significant economic and ritual importance in their society. Their pastoral lifestyle is closely tied to their distinctive social structure, religious practices (including sacred dairies known as “tu”), and traditional barrel-vaulted huts, all of which revolve around their buffalo herds, distinguishing the Todas from tribes primarily engaged in hunting, fishing, or settled agriculture.

The Toda Tribe of Nilgiri Hills:

Answer: (A) Sino-Tibetan

Explanation: Lepcha and Bhutia are languages belonging to the Sino-Tibetan language family, which is predominantly spoken across the Himalayan and northeastern regions of India, including Sikkim, Darjeeling, and parts of the northeast. The Sino-Tibetan family in India is generally divided into the Tibeto-Burman branch, which includes languages spoken by communities inhabiting the Himalayan foothills and northeastern hill tracts, such as the Lepchas (indigenous to Sikkim) and Bhutias (of Tibetan origin, settled in Sikkim and parts of West Bengal). This language family is distinct from the Indo-Aryan family, which dominates most of northern and central India, the Dravidian family found mainly in southern India, and the Austric family associated with certain tribal groups in central and eastern India.

Sino-Tibetan Language Family in India:

Answer: (B) Parsis

Explanation: The Parsis are a minority religious community in India who follow Zoroastrianism, an ancient monotheistic religion founded by the Prophet Zoroaster (Zarathustra) in ancient Persia. The Parsis migrated to India, primarily settling in Gujarat and later concentrating heavily in Mumbai, around the 8th–10th century CE to escape religious persecution following the Arab conquest of Persia. Despite being a very small community numerically, the Parsis have made disproportionately significant contributions to India’s industry, commerce, science, and culture, with prominent families such as the Tatas and Godrejs being of Parsi descent. Their religious practices center around fire temples, and they are distinct from Jains, Buddhists, and Christians, who follow entirely different religious traditions with different origins and histories in India.

Parsis and Zoroastrianism in India:

Answer: (B) Himachal Pradesh

Explanation: Kinnauri is a language spoken predominantly by the people of the Kinnaur district in the state of Himachal Pradesh, located in the western Himalayan region of India. It belongs to the Tibeto-Burman branch of the Sino-Tibetan language family, reflecting the region’s cultural and linguistic proximity to Tibetan-influenced Himalayan communities. The Kinnauri-speaking population inhabits the mountainous terrain of Kinnaur, where the language has several dialectal variations across different valleys, and the community also maintains a distinct cultural identity that blends both Hindu and Buddhist traditions, characteristic of the broader Himalayan cultural zone spanning Himachal Pradesh’s tribal belt.

Kinnauri Language and Kinnaur District:

Answer: (D) 21.8

Explanation: According to SRS (Sample Registration System) data linked to the Census of India 2011 period, the Crude Birth Rate (CBR) of India stood at 21.8 at the national level during 2011, exhibiting a decline of 0.3 points over 2010. The Crude Birth Rate refers to the number of live births per 1,000 population in a given year and is a key indicator used to assess population growth trends. India’s CBR has shown a consistent declining trend over the decades — from around 23.8 in 1991 and 22.8 in 2001 — reflecting improvements in family planning awareness, female literacy, healthcare access, and socio-economic development. There is significant state-wise variation, with the maximum CBR reported in Uttar Pradesh (27.8) and the minimum in Kerala (15.2).

Crude Birth Rate (CBR) of India:

Answer: (C) Kerala

Explanation: Kerala is the only major state in India that recorded a sex ratio favouring females over males, with a sex ratio of 1084 females per 1000 males according to the Census of India, 2011. This exceptional demographic feature is often attributed to Kerala’s high female literacy rate, better healthcare access, greater social awareness, and historically matrilineal social structures in certain communities (such as among the Nairs), all of which have contributed to better survival, health, and social status of women in the state compared to the rest of India, where the national sex ratio remains skewed in favour of males (943 per 1000 in 2011). This makes Kerala a demographic outlier among Indian states, distinct from Karnataka, West Bengal, and Odisha, all of which have male-favouring sex ratios, though better than the national average.

Sex Ratio Across Indian States (Census 2011):

Answer: (A) Mizoram

Explanation: Mizoram has the highest literacy rate among the north-eastern states of India, recording a literacy rate of around 91.58% as per the Census of India, 2011, making it one of the most literate states in the entire country, second only to Kerala at the national level. This exceptionally high literacy rate in Mizoram is attributed to strong missionary educational influence dating back to the colonial period, widespread establishment of schools by Christian missionaries, high social value placed on education within Mizo society, and relatively better educational infrastructure compared to other northeastern states such as Nagaland, Manipur, and Tripura, which, while also having relatively high literacy rates compared to the national average, still fall behind Mizoram.

Literacy Rates Among North-Eastern States (Census 2011):

Answer: (B) 20,000 to 49,999

Explanation: As per the Census of India’s town classification system, urban places are categorized into six classes based on population size, ranging from Class I (the largest) to Class VI (the smallest). A Class III urban place is defined as having a population between 20,000 and 49,999 persons. This hierarchical classification system is used by the Census Department to systematically categorize India’s urban centres for planning, administrative, and statistical purposes, helping to distinguish between large metropolitan cities, medium-sized towns, and smaller urban settlements based on their population size, which in turn correlates with the level of urban infrastructure, civic amenities, and economic activity typically found in each category.

Census of India — Town Classification by Population Size:

Answer: (C) Santhals

Explanation: The Santhals are one of the largest tribal communities in India, with their present habitat primarily concentrated in the plateau regions spanning Bihar, Jharkhand, Odisha, and West Bengal, particularly in areas like the Santhal Parganas of Jharkhand, which is named after this community. The Santhals belong to the Proto-Australoid racial group and speak Santhali, a language belonging to the Austric (Munda) language family. Traditionally, the Santhals have practiced settled agriculture, shifting cultivation, and forest-based livelihoods in the undulating plateau and forested terrain of the Chhotanagpur region, distinguishing them from tribes like the Bhils (concentrated in western/central India, particularly Rajasthan, Gujarat, Madhya Pradesh) and Nagas (concentrated in northeastern India, particularly Nagaland).

Santhal Tribe:

Answer: (D) Dravidian

Explanation: Kannada belongs to the Dravidian language family, which is predominantly spoken across southern India, including the states of Karnataka, Tamil Nadu, Andhra Pradesh, Telangana, and Kerala. The Dravidian language family is one of the major linguistic groups of India, distinct from the Indo-Aryan family that dominates northern and central India, and it includes other major languages such as Tamil, Telugu, and Malayalam, alongside several tribal languages spoken in scattered pockets across central India (such as Gondi and Kurukh). Kannada, as the official language of Karnataka, has a rich literary tradition dating back over a thousand years and is written in its own distinct script, reflecting the long-standing cultural and linguistic heritage of the Dravidian family in peninsular India.

Dravidian Language Family in India:

Answer: (C) Angami

Explanation: The Angami are a prominent tribal community native to Nagaland, a state in northeastern India, making them a classic example of a north-eastern Indian tribe. The Angamis are known for their distinct terraced wet-rice cultivation practiced on the hill slopes of Nagaland, along with their rich cultural traditions, including elaborate festivals like Sekrenyi, and their historically significant role in Naga society and politics. In contrast, the Oraon are primarily found in the Chotanagpur plateau region (Jharkhand, Odisha, West Bengal, Chhattisgarh) in eastern-central India, the Chenchu are a tribal community native to the forests of Andhra Pradesh and Telangana in southern India, and the Irula are found in the Nilgiri hills and adjoining regions of Tamil Nadu and Kerala in southern India, none of which belong to the northeastern tribal belt.

North-Eastern and Other Indian Tribes:

Answer: (B) 914

Explanation: As per the provisional results of the Census of India 2011 released by the Registrar General and Census Commissioner, the child sex ratio (0-6 years age group) for India was recorded at 914 females per 1000 males, marking an all-time low decline from 927 in the 2001 census. This continuing decline in child sex ratio, despite the overall sex ratio improving to 940 females per 1000 males at the national level in 2011, reflects persistent gender bias and preference for male children in many parts of the country, driven by socio-cultural factors such as dowry concerns, inheritance patterns, and old-age support expectations tied to sons. States like Haryana and Punjab recorded the lowest child sex ratios, while Mizoram and Meghalaya recorded the highest among Indian states.

Child Sex Ratio in India (Census 2011):

Answer: (B) 1872

Explanation: The first Census of India was conducted in 1872 during the tenure of Viceroy Lord Mayo, though it was conducted in a non-synchronous manner across different parts of the country at different times rather than on a single fixed date. This 1872 census is considered the first attempt at a nationwide population enumeration in India, even though it was not conducted with the same degree of uniformity and coordination as later censuses. The first synchronous census, where enumeration was conducted simultaneously across the entire country on a single reference date, was held in 1881 under Lord Ripon, and this 1881 census marked the beginning of the continuous, unbroken decennial census tradition in India that has continued every ten years since then (except for the postponed 2021 census due to the COVID-19 pandemic).

Census of India — Historical Origins:

Answer: (B) 1921

Explanation: The 1921 census year recorded a negative population growth rate of -0.31% in India, making it the only census in India’s modern demographic history to record a decline in population. This anomaly is primarily attributed to the devastating impact of the 1918-19 influenza pandemic (commonly known as the Spanish Flu), which killed an estimated 12-20 million people in India, combined with poor harvests and famine conditions in certain regions during this period. Because of this significant demographic disruption, the year 1921 is often referred to as the “Year of the Great Divide” in Indian demographic history, marking a turning point after which India’s population began a sustained and largely uninterrupted growth trajectory through subsequent censuses.

Negative Growth Rate — Census of India, 1921:

Answer: (B) 0.640

Explanation: India’s HDI value for 2017, as released in the UNDP’s Human Development Report 2018 (published in September 2018), stood at 0.640, placing the country in the “medium human development” category and ranking it 130th out of 189 countries. Between 1990 and 2017, India’s HDI value increased from 0.427 to 0.640, marking an improvement of nearly 50 percent, driven by significant gains in life expectancy, years of schooling, and per capita income. This growth reflected India’s broader progress in lifting large sections of its population out of poverty and improving human development indicators over nearly three decades, positioning India’s HDI value slightly above the South Asian regional average of 0.638 for that year.

Human Development Index (HDI) of India, 2017:

Answer: (B) 29 years

Explanation: According to Census projection reports, the average (median) age of an Indian was expected to reach 29 years by 2020, making India one of the youngest large nations in the world in terms of demographic profile. This relatively low average age reflects India’s favorable demographic dividend, where a very high proportion of the population falls within the working-age bracket (roughly 15-64 years), positioning India advantageously compared to aging populations in countries like Japan, Germany, and several Western European nations, where average ages are considerably higher. This demographic advantage has been widely cited as a potential driver of India’s future economic growth, provided adequate employment, skill development, and education opportunities are created to productively utilize this large young workforce.

India’s Average/Median Age Projections:

Answer: (C) 914

Explanation: As per the provisional results of the Census of India 2011, the child sex ratio (0-6 years age group) stood at 914 females per 1000 males, representing a decline from 927 in the 2001 census and marking the lowest recorded figure since independence. This decline occurred despite an improvement in the overall sex ratio of the country (which rose to 940 females per 1000 males in 2011), highlighting a specific and concerning trend of gender-selective practices affecting children, largely attributed to a continued societal preference for male children, particularly in northern and northwestern states such as Haryana and Punjab, which recorded the lowest child sex ratios in the country.

Child Sex Ratio in India (Census 2011):

Answer: (C) Oriya/Odiya

Explanation: Oriya (Odia), the official language of the state of Odisha, belongs to the Indo-Aryan language group, which is a branch of the larger Indo-European language family predominantly spoken across northern, western, and eastern India. The Indo-Aryan languages evolved from Sanskrit and Prakrit languages of ancient India and include major languages such as Hindi, Bengali, Marathi, Gujarati, Punjabi, and Odia, all sharing common linguistic roots and structural features. In contrast, Tamil belongs to the Dravidian language family (spoken mainly in southern India), Ladakhi belongs to the Sino-Tibetan family (spoken in the Ladakh region of the Himalayas), and Lushai (Mizo) also belongs to the Sino-Tibetan family (spoken in Mizoram, northeastern India), making Odia the correct choice among the given options as the sole Indo-Aryan language.

Indo-Aryan Language Family in India:

Answer: (C) Anaimalai hills

Explanation: The Kadar tribe is a small indigenous forest-dwelling community that primarily inhabits the Anaimalai hills, located in the border region between Kerala and Tamil Nadu in the Western Ghats of southern India. The Kadars are traditionally forest-dependent people, historically relying on hunting, gathering, and collection of minor forest produce such as honey, wax, and medicinal plants from the dense tropical forests of the Anaimalai range, which is also known for housing significant biodiversity, including the Anaimalai (elephant hill) range’s namesake elephant populations. The Kadars are recognized as one of the Particularly Vulnerable Tribal Groups (PVTGs) in India due to their small population size, pre-agricultural level of technology, and geographical isolation, distinguishing their habitat from other tribal groups associated with the Nilgiri, Palni, or Travancore hills.

Kadar Tribe and Anaimalai Hills:

Answer: (B) 1872

Explanation: The first census in India was conducted in 1872 during the tenure of Viceroy Lord Mayo, marking the earliest attempt at a nationwide population enumeration in the country. However, this 1872 census was conducted in a non-synchronous manner, meaning different regions of India were enumerated at different points in time rather than on a single common reference date, due to the logistical challenges of coordinating such a vast and diverse territory under colonial administration. It was only in 1881, under Viceroy Lord Ripon, that India conducted its first synchronous census, with enumeration carried out simultaneously across the entire country, marking the beginning of the unbroken decennial census tradition that continues to this day.

First Census of India:

Answer: (B) The Mediterraneous

Explanation: According to traditional racial classification schemes applied to India’s population (as per B.S. Guha’s classification, widely used in Indian anthropology and geography textbooks), the Mediterranean racial group constitutes the bulk of the Indian population, spread across large parts of the country, particularly in northern, central, and southern India. This group is characterized by a slender build, dark hair, and dolichocephalic (long-headed) features, and is considered to have migrated into India from the Mediterranean region in ancient times, contributing significantly to the development of India’s classical civilizations, including the spread of Dravidian languages in southern India. The other racial groups — Proto-Australoids (associated with tribal populations of central India), Mongoloids (concentrated in the Himalayan and northeastern regions), and Negritos (a very small, ancient population found mainly in isolated pockets like the Andaman Islands) — represent comparatively smaller proportions of India’s overall population.

Racial Classification of India’s Population:

Answer: (D) 6 lakh

Explanation: According to the Census of India 2011, the country has approximately 6.4 lakh (640,867) villages, making “about 6 lakh” the closest and most accurate approximation among the given options. India’s vast rural landscape is characterized by this enormous number of villages spread across diverse geographic and climatic zones, ranging from small hamlets with a handful of residents to larger revenue villages with populations in the thousands. This extensive village network underpins India’s predominantly rural character, with a significant majority of the population residing in these rural settlements, and has been a key consideration in the design of rural development programs, panchayati raj institutions, and infrastructure planning across the country.

Villages in India:

Answer: (B) Maharashtra

Explanation: As per the Census of India 2011, Maharashtra recorded the highest urban population among all Indian states, with approximately 50.8 million people residing in urban areas, reflecting the state’s high degree of urbanization driven by major metropolitan centres such as Mumbai, Pune, Nagpur, and Nashik. While Uttar Pradesh has the highest total population in the country, its urbanization level is comparatively lower, meaning a smaller proportion (and in absolute terms, fewer people) reside in urban areas compared to Maharashtra. Maharashtra’s economic dominance, driven by industrial, financial, and service sector growth centered around Mumbai (India’s financial capital) and other industrial hubs, has historically attracted large-scale rural-to-urban migration, contributing to its position as the state with the largest urban population base in India.

Urban Population of Indian States (Census 2011):

Answer: (B) Rural to Urban

Explanation: Rural to Urban migration is the dominant type of migration in India, driven primarily by the search for better employment opportunities, higher wages, improved access to education and healthcare, and overall better living standards available in urban centres compared to rural areas. This migration pattern has intensified significantly since India’s economic liberalization in 1991, as rapid urbanization, industrialization, and the growth of the service sector in cities have created a pull factor drawing large numbers of rural populations, particularly the working-age demographic, towards metropolitan and other urban areas, while agricultural distress, underemployment, and limited non-farm opportunities in rural areas act as push factors, together reinforcing this predominant migration trend across the country.

Migration Patterns in India:

Answer: (D) Proto-Australiods

Explanation: The tribal populations of central and southern India predominantly belong to the Proto-Australoid racial group, which is considered one of the earliest inhabitants of the Indian subcontinent. This racial group is characterized by features such as dark skin, wavy hair, broad noses, and a relatively short stature, and is associated with tribal communities such as the Santhals, Mundas, Oraons, Gonds, and Bhils, who inhabit the forested plateau regions of central India (Chotanagpur plateau, Central Indian tribal belt) as well as scattered pockets across southern India. This racial classification, based on B.S. Guha’s anthropological framework of India’s population, distinguishes these central-southern tribal groups from the Mongoloid populations of the Himalayan and northeastern regions, and from the Negrito populations found in isolated areas like the Andaman Islands.

Proto-Australoid Racial Group in India:

Answer: (B) 382 person per square km.

Explanation: As per the Census of India 2011, the population density of India stood at 382 persons per square kilometer, marking a significant increase from 325 persons per square kilometer recorded in the 2001 census. This rise in population density reflects India’s continued population growth over the preceding decade, even as the growth rate itself showed signs of deceleration compared to earlier decades. India’s population density varies dramatically across states and regions, with densely populated states like Bihar and West Bengal recording much higher figures, while sparsely populated states like Arunachal Pradesh and other Himalayan/northeastern states record significantly lower density values, reflecting the country’s vast geographic and demographic diversity.

Population Density of India (Census 2011):

Answer: (D) Cultivation

Explanation: The Gonds, one of the largest tribal communities in India, primarily inhabit the central Indian region spanning Madhya Pradesh, Chhattisgarh, Maharashtra, Andhra Pradesh, and Odisha, and their main traditional occupation is cultivation, particularly settled agriculture supplemented by shifting cultivation (locally known as “dahiya” or “bewar”) in more forested and hilly tracts. Over time, many Gond communities transitioned from purely shifting cultivation practices toward more settled forms of agriculture, growing crops such as millets, rice, and pulses, while also engaging in supplementary activities like forest produce collection and animal husbandry. The Gonds have a rich cultural heritage, including their own language (Gondi, belonging to the Dravidian family) and distinct art forms such as Gond painting, and historically ruled several kingdoms in central India (the Gond kingdoms) before British colonial rule, reflecting their settled agrarian and socio-political organization rather than a primarily hunting or food-gathering based economy.

Gond Tribe:

Answer: (A) Chandigarh

Explanation: Among Union Territories, Lakshadweep recorded the highest overall literacy rate in the Census of India 2011, but since it is not among the given options, Chandigarh holds the highest literacy rate (approximately 86.43%) among the listed choices — Chandigarh, Dadra and Nagar Haveli, Daman and Diu, and NCT of Delhi. Chandigarh’s high literacy rate is attributed to its well-planned urban infrastructure, being the joint capital of Punjab and Haryana, and the presence of numerous quality educational institutions, which have collectively fostered a strong educational environment. Delhi followed closely behind with a literacy rate of around 86.34%, while Daman and Diu and Dadra and Nagar Haveli, being smaller and historically less urbanized union territories, recorded comparatively lower literacy rates.

Literacy Rates Among Select Union Territories (Census 2011):

Answer: (C) Jharkhand

Explanation: Among the given options, Jharkhand recorded the lowest literacy rate in the Census of India 2011, at approximately 66.41%, ranking 32nd among all Indian states and union territories, well below the national average of 74.04%. This comparatively lower literacy rate in Jharkhand is largely attributed to its predominantly tribal and rural population, historically limited educational infrastructure, and socio-economic challenges in many of its districts. In comparison, Andhra Pradesh recorded around 67%, Assam around 72.2%, and Odisha around 72.9%, all of which were higher than Jharkhand’s literacy rate, making Jharkhand the state with the lowest literacy among the four options provided (though Bihar, not listed here, recorded the overall lowest literacy rate in India at that time).

Literacy Rates of Selected States (Census 2011):

Answer: (C) 181 million

Explanation: Between the 2001 and 2011 Census, India’s population increased by approximately 181.5 million (18.15 crore), rising from about 1,028.6 million in 2001 to approximately 1,210.6 million in 2011, representing a decadal growth rate of 17.7%. While this absolute increase was still substantial, reflecting India’s continued rapid population growth, it marked a notable deceleration in the decadal growth rate compared to the previous decade (2001-2011 rate of 17.7% versus the 1991-2001 rate of 21.5%), indicating an early sign of demographic transition and a slowing pace of population growth, largely attributed to declining fertility rates driven by improved family planning awareness, rising female literacy, and urbanization.

India’s Population Growth (2001-2011):

Answer: (A) a, b, d, c (Kerala, Mizoram, Goa, Tripura)

Explanation: As per the Census of India 2011, the literacy rates of the four states in descending order are Kerala (93.91%), Mizoram (91.58%), Goa (88.70%), and Tripura (87.75%). Kerala has consistently held the position of India’s most literate state due to its long-standing emphasis on public education, effective land reforms, strong healthcare systems, and social reform movements dating back to the pre-independence era. Mizoram follows closely, benefiting significantly from missionary-established educational institutions and a strong cultural value placed on education. Goa, with its relatively small population, high urbanization, and historical Portuguese-era educational institutions, ranks third, while Tripura, despite significant improvements in literacy over the decades due to strong educational initiatives, ranks fourth among this group, though still well above the national average.

Literacy Rates of Kerala, Mizoram, Goa, Tripura (Census 2011):

Answer: (B) Santhali

Explanation: Santhali is the most widely spoken language belonging to the Indo-Austric (Austro-Asiatic), specifically the Munda branch, in India. It is the mother tongue of the Santhal tribe, one of India’s largest tribal communities, primarily concentrated in the plateau regions of Jharkhand, West Bengal, Odisha, and Bihar. Santhali holds the distinction of being the only Austro-Asiatic language included in the Eighth Schedule of the Indian Constitution, reflecting its significant speaker base and cultural importance. It also has its own unique script, called Ol Chiki, developed by Pandit Raghunath Murmu in the mid-20th century, which distinguishes it further from other Munda languages like Khasi, Munda, and Kharia, which, while significant regionally, have considerably smaller speaker populations compared to Santhali.

Austro-Asiatic (Indo-Austric) Languages of India:

Answer: (D) Bhil

Explanation: Among the Scheduled Tribes of India, the Bhils are recognized as having a “dispersed core” pattern of habitation, meaning their population is spread across a wide geographical area spanning multiple states — Rajasthan, Gujarat, Madhya Pradesh, and Maharashtra — without being concentrated within a single, well-defined core region. This is in contrast to tribes like the Santhals (concentrated primarily around the Santhal Parganas region of Jharkhand), the Garos (concentrated in the Garo Hills of Meghalaya), and the Aos (concentrated primarily in the Mokokchung district of Nagaland), all of which exhibit a more geographically concentrated, single-core settlement pattern. The Bhils’ dispersed distribution across the tribal belt of western-central India reflects their historical migration patterns and adaptation to the diverse hilly and forested terrains spanning these four states.

Scheduled Tribes — Core Distribution Patterns:

Answer: (A) 1st Five Year Plan

Explanation: India launched its official Family Planning Programme, based on voluntary methods including sterilization and contraception, in 1952, during the First Five-Year Plan (1951-56), making India the first country in the world to launch a government-sponsored family planning programme aimed at population control. This early initiative reflected the recognition by India’s post-independence planners of the need to address rapid population growth as a challenge to economic development, even though the initial budgetary allocation was extremely modest (just Rs 0.1 crore in the First Plan). The programme’s approach evolved considerably over subsequent plans — becoming more target-driven and controversial in later years (particularly during the Emergency period under the Fifth Plan), before reverting to a purely voluntary basis following the Janata Government’s 1977 population policy reforms.

Family Planning and Sterilization Policy in India:

Answer: (D) Nilgiri hills

Explanation: The habitat of the Toda tribe is located in the Nilgiri hills, situated in the western part of Tamil Nadu in southern India. The Todas are an indigenous pastoral community whose traditional way of life revolves around buffalo herding, and their settlement pattern is closely tied to the unique high-altitude grassland (shola) ecosystem of the Nilgiris, which provides suitable grazing conditions for their buffalo herds. The Nilgiri hills, part of the Western Ghats mountain range, are also home to several other tribal communities such as the Kota, Badaga, and Kurumba, each occupying distinct ecological and economic niches within this biodiverse hill region, distinguishing the Nilgiris from the Aravalli range (Rajasthan), Siwalik range (sub-Himalayan belt), and Kaimur range (Madhya Pradesh/Bihar/Uttar Pradesh border region).

Toda Tribe and Nilgiri Hills:

Answer: (B) Manipur

Explanation: Among the given north-eastern states, Manipur has the lowest percentage of Scheduled Tribes population, at approximately 35.1% as per the Census of India 2011. This is notably lower than Mizoram, which has the highest Scheduled Tribe proportion in the entire country at around 94.4%, followed by Nagaland at approximately 86.5%, and Arunachal Pradesh at around 68.8%. Manipur’s comparatively lower ST percentage is because the state’s population is more evenly divided between the tribal hill areas (inhabited by communities such as the Nagas and Kukis) and the non-tribal Meitei-dominated Imphal valley, which houses a significant portion of the state’s total population, thereby diluting the overall percentage share of Scheduled Tribes compared to states like Mizoram and Nagaland, where tribal populations are overwhelmingly dominant across almost the entire state.

Scheduled Tribe Population Percentage — North-Eastern States (Census 2011):

Answer: (B) 17.64%

Explanation: According to the Census of India 2011, India accounted for approximately 17.64% of the total world population, despite occupying only about 2.4% of the world’s total land area, making it the second most populous country globally after China at that time. This vast population share, combined with India’s relatively limited land area, has historically resulted in extremely high population density and significant pressure on the country’s natural resources, infrastructure, and public services, and has been a central consideration in India’s development planning and policy formulation across successive Five-Year Plans, particularly regarding food security, urbanization, healthcare, and employment generation for its enormous population base.

India’s Share of World Population (Census 2011):

Answer: (C) More than 75% of the population engaged in primary sector

Explanation: According to the Census of India’s definition of a “town” (specifically referring to a Census Town, as opposed to a Statutory Town), the criteria include a minimum population of 5,000 persons, a population density of at least 400 persons per square kilometer, and at least 75% of the male working population engaged in non-agricultural (non-primary sector) pursuits — not the primary sector. This option is therefore incorrect as stated, since the actual census criterion requires a high proportion of the population to be engaged in non-agricultural activities (secondary/tertiary sectors), reflecting urban economic characteristics, rather than requiring a high proportion in the primary sector (agriculture), which is characteristic of rural areas. The presence of statutory bodies like a Municipal Corporation, Municipality, or Cantonment Board is a separate criterion applicable to Statutory Towns.

Census of India — Definition of a Town:

Answer: (A) Ripley

Explanation: The Zones and Strata theory pertaining to the origin and diffusion of human races was propounded by William Zebina Ripley, an American economist and anthropologist, in his influential 1899 work “The Races of Europe.” Ripley’s theory proposed that human racial types could be understood in terms of successive geographical zones and strata of migration and settlement, where different racial groups spread and settled in layers or strata across different zones over time, influenced by geographic and environmental factors. This theory was significant in the development of anthropological and racial classification studies in the late 19th and early 20th centuries, distinguishing Ripley’s contribution from other scholars like Taylor (known for environmental determinism in geography), Huntington (known for climatic determinism theories), and Baker (known for other geographical classification frameworks).

Zones and Strata Theory:

Answer: (A) 1921

Explanation: The year 1921 is considered the “Year of the Great Divide” in the demographic history of India because it marks a fundamental turning point in the country’s population growth trajectory. Prior to 1921, India’s population growth was erratic and often negative or stagnant, largely due to recurrent famines, epidemics (such as the devastating 1918-19 influenza pandemic), and high mortality rates. However, after 1921, India’s population began a sustained and continuous upward growth trend that has persisted through every subsequent census, driven by gradual improvements in public health, sanitation, famine control measures, and medical advancements that led to declining death rates while birth rates remained relatively high. This structural shift from a stagnant/declining population trend to consistent growth is why demographers and geographers mark 1921 as this pivotal dividing point in India’s population history.

1921 — The “Year of the Great Divide” in Indian Demography:

Answer: (C) 74.04 percent

Explanation: According to the Census of India 2011, the overall literacy rate of India was recorded at 74.04%, marking a significant improvement from 65.38% (some sources cite 64.83%) in the 2001 census, reflecting substantial progress in educational access and awareness across the country over the preceding decade. This overall figure comprised a male literacy rate of 82.14% and a female literacy rate of 65.46%, highlighting a persistent gender gap in literacy despite the overall improvement. This growth in literacy has been attributed to various government initiatives such as the Sarva Shiksha Abhiyan (SSA), the Right to Education Act (2009), and increased investment in primary and secondary education infrastructure across both rural and urban areas of the country.

Literacy Rate of India (Census 2011):

Answer: (A) West Bengal

Explanation: Among the given options, West Bengal has the highest Scheduled Caste (SC) population in absolute numbers, with the state hosting one of the largest SC populations in India (second only to Uttar Pradesh at the national level, which is not among the given options). West Bengal’s substantial SC population is spread across various castes such as Namasudra, Rajbanshi, and Bagdi, among others, reflecting the state’s historical caste demographics rooted in its agrarian and riverine geography. In contrast, Mizoram and Tripura, being predominantly tribal north-eastern states, have very small SC populations (with Mizoram in particular being almost entirely Scheduled Tribe-dominated), while Haryana, despite having a relatively higher SC percentage of its total state population, has a much smaller absolute SC population compared to the much larger and more populous West Bengal.

Answer: (B) Haryana

Explanation: Haryana recorded the lowest sex ratio among Indian states in the 2011 Census, at 879 females per 1000 males, making it the state with the most skewed sex ratio in the entire country. This significant gender imbalance in Haryana has been attributed to deep-rooted son preference, female foeticide (illegal sex-selective abortion), and patriarchal social structures prevalent in parts of the state, issues that gained national attention and prompted government interventions such as the “Beti Bachao, Beti Padhao” (Save the Daughter, Educate the Daughter) campaign, which was notably launched from Haryana’s Panipat district in 2015 to address this specific demographic crisis. In comparison, Punjab, while also having a relatively low sex ratio, recorded a somewhat better figure than Haryana, while Sikkim and Jammu & Kashmir, though also below the national average in some respects, did not record as extreme a gender imbalance as Haryana.

Sex Ratio Among Selected Indian States (Census 2011):

Answer: (D) 53

Explanation: According to the Census of India 2011, the number of “million-plus” cities (Urban Agglomerations/Cities with a population of one million or more) in India stood at 53, marking a substantial increase from 35 such cities recorded in the 2001 census. This significant rise reflects India’s accelerating pace of urbanization over the decade, driven by rural-to-urban migration, industrial and service sector growth, and the expansion of metropolitan areas. These 53 million-plus cities collectively house a substantial share of India’s urban population, with major examples including Mumbai, Delhi, Kolkata, Chennai, Bengaluru, Hyderabad, and Ahmedabad among the largest, alongside several tier-2 cities that crossed the million-population threshold for the first time in this census.

Million-Plus Cities in India (Census 2011):

Answer: (C) Meghalaya

Explanation: Meghalaya recorded the highest decadal population growth rate among Indian states during the 2001-2011 period, at approximately 27.82% (some sources cite 27.80% or 27.95%), significantly higher than the national average decadal growth rate of 17.64% for the same period. This exceptionally high growth rate in Meghalaya is largely attributed to relatively higher birth rates in the state compared to other regions, with its predominantly tribal population (around 86% Scheduled Tribe, mainly Khasi, Garo, and Jaintia communities) generally exhibiting higher fertility patterns. Among the given options, Punjab and Kerala recorded relatively lower and more moderate growth rates typical of demographically more advanced states, while Pondicherry (Puducherry), despite having a notable growth rate as a smaller union territory, did not surpass Meghalaya’s figure.
