Demographics & Migration — Study Notes
Overview
Demographics and migration constitute a vital intersection of geography, economics, and public policy — topics that appear regularly in UPSSSC PET. Questions test your grasp of India's census data (population, growth, literacy, sex ratio), state-level variations, and migration trends. Understanding these concepts helps you interpret data-based questions and connect demographic patterns to development policies.
For UPSSSC PET, expect 2–3 questions from this topic, often appearing as direct fact recall (e.g., census year, sex ratio definition) or data interpretation from tables/graphs showing state-wise population or literacy. Mastering census terminology, decadal trends (especially 2001 and 2011), and Uttar Pradesh-specific figures gives you a scoring edge. Migration questions focus on rural-urban flows, seasonal labour movement, and push-pull factors.
The Census of India — conducted every 10 years since 1872 (first synchronous census 1881) — is the world's largest administrative exercise. Census 2021 was postponed due to COVID-19. Your preparation must prioritize Census 2011 data, which remains the latest official baseline for demographic questions.

Two phases — house-listing (administrative data) and population enumeration (demographic details). Census data informs parliamentary delimitation, fund allocation, and planning.
