110. What was the population density of India as recorded by Census 2011?
[RRB NTPC Undergraduate CBT-I, 18 Aug 2025 Shift 2]
A. 382 persons/km²
B. 325 persons/km²
C. 500 persons/km²
D. 450 persons/km²
Answer: A. 382 persons/km²
Explanation: India’s 2011 density stood at 382 residents per square kilometre, up from 325 in 2001. Population density divides the number of persons by geographical area and is particularly useful for comparing differently sized regions.
109. Which state had the second-highest population density in Census 2011?
[RRB NTPC Undergraduate CBT-I, 11 Aug 2025 Shift 2]
A. Madhya Pradesh
B. Maharashtra
C. Uttar Pradesh
D. West Bengal
Answer: D. West Bengal
Explanation: West Bengal’s density was 1,029 persons per square kilometre, ranking second among states after Bihar’s approximately 1,106. Union Territories such as Delhi can be denser but are not included in a state-only ranking.
108. Which district was India’s most populous in Census 2011?
[SSC Selection Post, 1 Aug 2025 Shift 3]
A. Thane
B. North 24 Parganas
C. Bengaluru
D. Pune
Answer: A. Thane
Explanation: Thane district in Maharashtra had the highest recorded district population at the time of Census 2011. Its administrative boundaries were later changed when Palghar was carved out, so comparisons must retain the historical 2011 district definitions.
107. At what interval is a population census normally conducted in India?
[SSC Selection Post, 1 Aug 2025 Shift 1]
A. Every 5 years
B. Every 10 years
C. Every 15 years
D. Every 20 years
Answer: B. Every 10 years
Explanation: India has historically conducted a decennial census, meaning an interval of ten years. The 2021 round was postponed, but that unusual delay does not alter the customary ten-year frequency established in India’s census history.
106. Which state registered negative decadal population growth in Census 2011?
[SSC Selection Post, 30 Jul 2025 Shift 1]
A. Nagaland
B. Kerala
C. Goa
D. Assam
Answer: A. Nagaland
Explanation: Nagaland was unique among states for its population decrease over the 2001–2011 decade. Kerala grew slowly but did not experience a negative total population change, making it different from Nagaland in this comparison.
105. What was India’s overall literacy rate in the 2011 Census?
[RRB NTPC Graduate CBT-I, 23 Jun 2025 Shift 3]
A. 72.98%
B. 76.23%
C. 74.04%
D. 75.12%
Answer: C. 74.04%
Explanation: The final 2011 literacy figure was 74.04% for people aged seven or older. Male literacy was 82.14% and female literacy 65.46%. Literacy in the census requires reading and writing with understanding.
104. Which of these states recorded no Scheduled Tribe population in Census 2011?
[RRB NTPC Graduate CBT-I, 23 Jun 2025 Shift 1]
A. Punjab
B. Odisha
C. Maharashtra
D. Kerala
Answer: A. Punjab
Explanation: Punjab recorded no population classified as Scheduled Tribes in the 2011 census tables. The constitutional schedule of recognised tribes varies by state, and the absence of a notified ST population does not mean there are no socially diverse communities.
103. What was India’s overall sex ratio according to Census 2011?
[RRB NTPC Graduate CBT-I, 11 Jun 2025 Shift 2]
A. 950
B. 948
C. 940
D. 943
Answer: D. 943
Explanation: The sex ratio increased to 943 females per thousand males in the final 2011 figures. This indicator measures the total population. The child sex ratio for ages zero to six was lower, at 919, and must be treated separately.
102. Which district of Madhya Pradesh had the largest rural population according to Census 2011?
[MPPSC Assistant Professor GS, 1 Jun 2025]
A. Rewa
B. Dindori
C. Satna
D. Sidhi
Answer: A. Rewa
Explanation: Rewa had the largest rural population among the districts in this question. Large district totals depend on both total district population and the proportion classified as rural, so the figure is not the same as rural population percentage.
101. Which group comprises Madhya Pradesh districts with relatively low decadal population growth in 2001–2011?
[MPPSC Assistant Professor Geography, 1 Jun 2025]
A. Anuppur, Betul and Mandsaur
B. Anuppur, Betul and Chhindwara
C. Chhindwara, Mandsaur and Balaghat
D. Neemuch, Betul and Chhindwara
Answer: B. Anuppur, Betul and Chhindwara
Explanation: Anuppur, Betul and Chhindwara were identified as the relevant lower-growth group in the examination. Decadal population growth measures percentage change over ten years and is influenced by births, deaths, migration and administrative consistency.
