Paper I

Paper I — Settlement geography · rural, urban

Story hook

In 1928, the French geographer Albert Demangeon stood in the village of Préchac in Gascony and asked a deceptively simple question: why is this house here, and not over there? The answer led to four decades of géographie de l'habitat rural — the geography of the rural dwelling. Demangeon and his student Jean Brunhes documented, with painstaking field surveys, how a single French village contained traces of Gallo-Roman centuriation, mediaeval bocage parcels, 19th-century enclosure movements, and 20th-century state roads. The settlement was a palimpsest — a manuscript written and partly erased and written again across two thousand years.

Meanwhile in Heidelberg in 1933, Walter Christaller mapped the towns of southern Germany onto a hexagonal lattice (see Economic Geography module) and made urban settlement a science of regularities — towns are not random, they follow range and threshold. In 1949, the Indian geographer R.L. Singh of Banaras Hindu University began publishing the Indian village-typology series that would dominate Indian settlement geography for half a century. Singh's typology — clustered, semi-clustered, hamleted, dispersed — entered every NCERT chapter and remains the canonical Mains optional answer.

In 2024, 6.6 billion people lived on Earth and 4.6 billion (56%) of them lived in urban areas. United Nations World Urbanization Prospects (2024 revision) projected this share would reach 68% by 2050. India alone is set to add 416 million urban residents by 2050, more than any other country. Settlement geography — the spatial logic of where humans choose to live — is moving from the academic margin to the policy centre. This module is what UPSC Mains Optional Geography Paper I expects you to know about rural and urban settlements.

Why this matters for UPSC

Paper I Settlement Geography is a near-certain 20-mark question in every Mains Optional paper. Examiners favour the dichotomy question ("rural vs urban", "primate city vs rank-size", "compact vs dispersed") and the Indian-application question (Census Town status, smart cities, JNNURM evolution). Candidates who memorise only NCERT-level patterns lose marks; the optional rewards familiarity with Demangeon, Brunhes, Hudson, Stewart, Berry, Mumford, Lewis Mumford, Harris-Ullman and the contemporary critique. Add the Indian Census 2011 settlement data (with the 2021 census postponement caveat) and you have a robust 250-word answer.
