✍️ Usage in a UPSC answer

India's rapid urbanisation — with the urban population growing from 17.3% (1951) to 31.1% (Census 2011) — has generated a 'dual city' phenomenon where gated enclaves of prosperity exist alongside vast informal settlements lacking basic amenities.

🎯 How This Word Works in UPSC Writing

The rising share of a population living in urban areas, together with the changes in work, settlement and social relations that accompany it. For GS1 the distinction worth drawing is between urbanisation driven by economic pull and distress-driven migration, because they produce very different settlement patterns and service demands. Census definitions also matter, since what counts as urban is a statutory and demographic judgement rather than a fact of geography.

⚖️ Don’t Confuse It With

Urbanisation is the increasing share of population in urban areas. Urban growth is the absolute increase in urban population, which can rise even if the share does not. Urbanism is the way of life characteristic of cities. Suburbanisation and peri-urban growth describe expansion at the city edge.

🇮🇳 Hindi Meaning

शहरीकरण (shahrīkaran) or नगरीकरण (nagarīkaran).
