Census — RRB NTPC Static GK

• Key Fact: The first regular (decadal) census in India was conducted in 1881 during the tenure of Lord Ripon.
Supporting Detail: Prior to this, the first non-synchronous census was held in 1872 under Lord Mayo, but it lacked proper comprehensive data collection.
Related Concept: From 1881 onwards, it was established that the census would be conducted uninterruptedly every 10 years.
Why others wrong: 1872 is the first census, but not the regular one. 1951 is the first post-independence census.
Exam Trick: Remember 'Mayo-72' (First) and 'Ripon-81' (Regular/Decadal) to easily eliminate options.
Additional Info: The USA was the first country to start the tradition of a 10-year decadal census in 1790.

• Key Fact: The Census is conducted by the Central Government under Article 246 of the Indian Constitution, falling under the Union List.
Supporting Detail: Specifically, it comes under Entry 69 of the 7th Schedule of the Constitution.
Related Concept: Being in the Union List means only the Parliament has the exclusive power to make laws regarding the Census.
Why others wrong: It is strictly a central subject, not state or concurrent. Article 82 deals with Delimitation, and Article 11 with Citizenship.
Exam Trick: Census covers the entire 'Union' of India uniformly, hence it must be a Union List subject (Article 246).
Additional Info: The legal framework is provided by the Census Act of 1948.

• Key Fact: Famous sand artist Sudarsan Pattnaik from Odisha has been appointed as the brand ambassador for the 2026-27 Census.
Supporting Detail: The official mascots for this census are 'Vikas' (representing males) and 'Pragati' (representing females).
Related Concept: Sudarsan Pattnaik was awarded the Padma Shri in 2014 and is globally recognized for his sand art.
Why others wrong: Mrityunjay Kumar Narayan is the Registrar General, and C. Chandramouli was the head during the 2011 Census.
Exam Trick: Link the goal of the census—Progress & Development—to the Hindi words 'Pragati' & 'Vikas'.
Additional Info: The 2011 Census mascot was 'Pragnak Shikshika' (a female enumerator).

• Key Fact: The period from 1911 to 1921 recorded a negative population growth rate, and hence the year 1921 is called the "Year of the Great Divide".
Supporting Detail: The population actively decreased during this decade due to severe famines, droughts, and epidemics (like influenza/cholera).
Related Concept: After 1921, India's population has seen continuous growth in every successive census without ever declining again.
Why others wrong: Growth was positive in all other decades. For instance, 2001-2011 saw a high growth of ~17.5%.
Exam Trick: 1921 = The Great Divide (Maha Vibhajak). It is the ONLY decade showing negative growth (-0.03% annually).
Additional Info: SSC exams frequently ask this specific year. From 1921 onwards, India entered the second stage of demographic transition.

• Key Fact: The 2026-27 Census is designed to be 100% digital, utilizing mobile apps (like the House Listing Operation app) across 16 languages.
Supporting Detail: The census is divided into two phases. Phase 1 focuses on housing (house listing and amenities), while Phase 2 focuses on population and individual data.
Related Concept: It also introduces a 'Self Enumeration' portal, allowing citizens to fill in their data online directly.
Why others wrong: Statement 3 is incorrect because Phase 1 is for Housing, not population counting (which happens in Phase 2).
Exam Trick: Remember the sequence: First you find the House (Phase 1), then you count the People inside it (Phase 2).
Additional Info: 34 lakh employees will be deployed for this massive digital exercise.

• Key Fact: In 2011, Bihar recorded the highest population density among states (1106 persons/sq km), and Arunachal Pradesh recorded the lowest (17 persons/sq km).
Supporting Detail: Overall for India, the population density stood at 382 persons per square kilometer.
Related Concept: If Union Territories are included, Delhi has the absolute highest density (11,320 persons/sq km), and Andaman & Nicobar has the lowest (46 persons/sq km).
Why others wrong: UP has the highest total population, not density. Sikkim has the lowest total population, not density.
Exam Trick: Do not confuse 'Population' with 'Population Density'. Pop Max = UP; Density Max = Bihar.
Additional Info: West Bengal follows Bihar closely as the state with the second-highest population density.

• Key Fact: For census calculations, a person aged 7 years and above who can both read and write with understanding is treated as literate.
Supporting Detail: India's overall literacy rate in 2011 was 74% (Males: 82.14%, Females: 65.46%).
Related Concept: Children below the age of 7 are strictly treated as illiterate, even if they attend a school and have learned to read/write a few words.
Why others wrong: The standard cutoff age set by the Ministry of Home Affairs is 7 years, not 5 or 10.
Exam Trick: Think of age 7 as standard 'Class 2' age—the baseline for measuring real literacy capability in census data.
Additional Info: Kerala remains the most literate state (94%), while Bihar is the least literate state (61%).

• Key Fact: World Population Day is observed on July 11th because on this exact date in 1987, the global population officially reached 5 billion (5 Arab).
Supporting Detail: Following this milestone, the day was first celebrated internationally in 1989.
Related Concept: The United Nations Population Fund (UNFPA) is the body responsible for releasing global population stability reports.
Why others wrong: Sweden's first modern census was in 1749, and USA's decadal census began in 1790, completely unrelated to the July 11 date.
Exam Trick: 5 Billion on 11th July 1987 = 11 July Population Day.
Additional Info: Currently, India holds the position of the most populous country in the world, crossing 142 crore people.

• Key Fact: According to the 2011 Census, India's rural population constitutes approximately 68.8% (or 68.84%), while the urban population is about 31.2% (or 31.16%).
Supporting Detail: Himachal Pradesh has the highest proportion of rural population (around 90%), making it the least urbanized state.
Related Concept: Conversely, Goa is the most urbanized state, with roughly 62% of its population living in urban areas and 37% in rural areas.
Why others wrong: 74% is India's overall literacy rate, not rural population percentage.
Exam Trick: Remember the ~69:31 split. India still heavily resides in its villages.
Additional Info: Among Union Territories, Delhi is highly urbanized, with around 97% urban population.

• Key Fact: For the high-altitude/difficult terrain areas (Ladakh, J&K, Himachal Pradesh, Uttarakhand), the census data collection is specifically scheduled to begin earlier, from 1st October 2026.
Supporting Detail: This early scheduling accommodates the severe winter weather conditions in these regions, ensuring completion before heavy snowfall restricts movement.
Related Concept: For the rest of the country (plains and majority areas), the population phase will start later, from 1st March 2027.
Why others wrong: 1 April 2026 is when Phase 1 (Housing) generally kicks off. 1 March 2027 is for plain areas.
Exam Trick: High altitudes get covered before the harsh winter peaks; hence, the October start date.
Additional Info: The entire process involves mapping, housing census, and individual counting, fully backed by GPS and mobile tech.
