A Geospatial Mapping of Socio-Economic Attributes of Ludhiana District, Punjab (India)

Abstract

This study examines the geospatial socio-economic attributes of Ludhiana district, Punjab, using Census data from 1991 and 2001 to map spatial and temporal variations. Despite its physiographic homogeneity—flat alluvial plains (100-120m elevation), Satluj River floodplains, semi-arid climate, and fertile irrigated soils supporting high agricultural productivity—Ludhiana exhibits heterogeneous human responses driven by urbanization, industrialization (textiles, leather), and transport networks (NH-1, NH-95). Key objectives include delineating socio-economic characteristics, analyzing female marginalization via Work Participation Rate (WPR) and sex ratio patterns, and mapping development disparities. Methodology employs Natural Breaks classification, growth rate formulas, Z-scores for composite indices, and simple percentages for indicators like literacy and WPR, ensuring comparability across censuses. Results reveal shifts: Population distribution evolved from even agricultural scatter (1991) to urban-centric concentration near Ludhiana, Machhiwara, and Jagraon (2001), with density intensifying along highways and city peripheries. Growth was moderate district-wide but high near rivers and urban edges, signaling migration and industrial spillovers. Sex ratio declined near urban centers (low/very low categories expanded), indicating male-dominated rural-urban migration and female marginalization in productive sectors, aligning with feminization of agriculture. Literacy surged homogenously, especially post-1991 economic reforms, while overall WPR equalized due to Green Revolution diffusion; female WPR lagged (26.94% vs. male 41.24% in 2001). Non-agricultural workers rose near cities (50% share in 2001 vs. 25% in 1991), reducing agricultural dependence peripherally. A composite development index confirms urban proximity drives progress, underscoring anthropogenic over natural factors in shaping socio-economic landscapes. Ludhiana defies environmental determinism, emerging as a varied human ecological space amid migration, gender inequities, and infrastructure-led growth.
