Q100. According to Census 2011, what was the sex ratio among the Scheduled Tribe population in India?
[RRB NTPC UG CBT-I, 19 June 2026, Shift 1]
(A) 970
(B) 990
(C) 1,010
(D) 950
Answer: (B) 990
Explanation: The 2011 enumeration recorded 990 females for every 1,000 males among Scheduled Tribes, higher than the overall national ratio of 943. This distinction matters because tribal sex ratios and India’s aggregate sex ratio are different census indicators.
Q99. Which state had the largest population of children aged 0–6 years according to provisional Census 2011 figures?
[RRB NTPC UG CBT-I, 19 June 2026, Shift 1]
(A) Maharashtra
(B) Bihar
(C) Rajasthan
(D) Uttar Pradesh
Answer: (D) Uttar Pradesh
Explanation: Uttar Pradesh contained the largest absolute number of children aged below seven, reflecting its position as India’s most populous state. The question asks about number of children, not the percentage of children within a state’s population.
Q98. Which Union Territory had the lowest literacy rate in Census 2011?
[RRB NTPC UG CBT-I, 18 June 2026, Shift 3]
(A) Lakshadweep
(B) Chandigarh
(C) Dadra and Nagar Haveli
(D) Andaman and Nicobar Islands
Answer: (C) Dadra and Nagar Haveli
Explanation: Among the then Union Territories, Dadra and Nagar Haveli had the lowest literacy rate, approximately 76.24%. The comparison uses the administrative boundaries existing at the 2011 Census, before the later merger with Daman and Diu.
Q97. Which state has high population density due to early human settlement and development?
[RRB NTPC UG CBT-I, 15 June 2026, Shift 2]
(A) Rajasthan
(B) Uttar Pradesh
(C) Meghalaya
(D) Sikkim
Answer: (B) Uttar Pradesh
Explanation: Uttar Pradesh occupies much of the fertile Ganga Plain, where plentiful water, level land, productive soils and long-established settlements have supported dense populations for centuries. Arid and mountainous states generally have fewer people per square kilometre.
Q96. Population density is defined as the number of people per:
[RRB NTPC UG CBT-I, 14 June 2026, Shift 2]
(A) Total population
(B) Unit of land area
(C) Urban centre
(D) Arable land
Answer: (B) Unit of land area
Explanation: Population density expresses how many inhabitants occupy a unit of land area, conventionally one square kilometre. Census 2011 reported India’s population density as 382 persons per square kilometre, allowing geographical comparisons between regions of unequal size.
Q95. Which among these States or Union Territories had the lowest sex ratio according to Census 2011?
[RRB NTPC UG CBT-I, 13 June 2026, Shift 2]
(A) Haryana
(B) Chandigarh
(C) Delhi
(D) Daman and Diu
Answer: (D) Daman and Diu
Explanation: The former Union Territory of Daman and Diu recorded approximately 618 females per 1,000 males, the lowest ratio among the listed territories. Male-dominated industrial migration was an important contributor to this unusual imbalance.
Q94. In 1951, approximately what percentage of India’s population lived in urban areas?
[SSC GD Constable, 30 May 2026, Shift 3]
(A) 17.3%
(B) 41.3%
(C) 37.3%
(D) 27.3%
Answer: (A) 17.3%
Explanation: India remained overwhelmingly rural at the first post-independence census. Urban residents represented approximately 17.3% of the population in 1951, compared with roughly 31.2% in 2011. The increase illustrates long-term urbanisation and structural economic change.
Q93. In how many phases will India’s next population census be conducted?
[SSC GD Constable, 30 May 2026, Shift 2]
(A) Two
(B) Three
(C) Four
(D) Five
Answer: (A) Two
Explanation: The planned census uses two major operational stages: houselisting and housing enumeration, followed by population enumeration. Separating these stages helps enumerators compile information on buildings and household amenities before gathering person-level demographic details.
Q92. The Technical Group on Population Projections projects how many crore Indians aged 60 or above by 2036?
[SSC GD Constable, 29 May 2026, Shift 3]
(A) 15 crore
(B) 23 crore
(C) 31 crore
(D) 35 crore
Answer: (B) 23 crore
Explanation: The Population Projections report for 2011–2036 anticipates roughly 22.7 crore people aged at least 60 by 2036, commonly rounded to 23 crore. Longer life expectancy and declining fertility increase the elderly share of India’s population.
Q91. Which was India’s largest metropolitan city by population according to Census 2011?
[SSC GD Constable, 22 May 2026, Shift 1]
(A) Kolkata
(B) Delhi
(C) Mumbai
(D) Chennai
Answer: (C) Mumbai
Explanation: Mumbai’s urban agglomeration counted about 18.4 million residents in 2011, more than Delhi and Kolkata. An urban agglomeration includes contiguous settlements beyond the municipal core, so its population differs from a narrowly defined city-proper total.
