Regions are analytical devices for reading spatial unevenness, but their delimitation is also a political-economic act. For formal regions, the task is to identify contiguous areas that share measurable uniformity, not merely areas linked by flows.

Delimiting formal regions. The first criterion should be the purpose of the region: physical, economic, social-cultural or administrative. Formal regions require homogeneity in one or more attributes, a clear threshold, an appropriate scale, and administrative feasibility. Nodality and programmatic criteria—flows, market areas, or administrative mandates—should be used only as secondary checks; they define functional or program regions, not formal homogeneity. Indicators may be physical (climate, soil, physiography, vegetation), economic (crop pattern, industrial output, employment, income, trade) or social-cultural (language, religion, caste, literacy, migration). Techniques should begin with selecting comparable units, such as districts or tehsils, standardising indicators, and using factor analysis or PCA to reduce multicollinearity. Cluster analysis, such as hierarchical or k-means, can then group units by similarity. GIS overlay, spatial autocorrelation and threshold mapping should test contiguity, boundary stability and data gaps. A feasible procedure is: define the question, collect district-level data, test indicator reliability, choose clusters, overlay with administrative boundaries, and validate with local knowledge. For formal regions, the boundary should be where the indicator value changes sharply, not where interaction decays. This avoids arbitrary political boundaries unless they coincide with natural homogeneity. India’s Planning Commission’s 15 agro-climatic zones illustrate this logic. Gravity models and break-point rules are better reserved for functional regions; using them for formal regions would confuse homogeneity with interaction.

Boundaries and geopolitics. Boundaries matter because they are power containers, territorial traps and geopolitical constructs. They define sovereignty, jurisdiction, resource rights and identity, and they can trap populations, enclaves or economic opportunities within fixed lines. They also shape strategic depth, alliance politics and control of chokepoints. Inclusionary aspects decide who is counted as a citizen, who can access land, water, welfare and labour markets, and which identities are recognised. In India, linguistic reorganisation, citizenship registration in border states, and river-basin management show how inclusion shapes political stability. Inclusion can also be positive through border trade, cross-border water sharing and cultural recognition. Exclusionary aspects produce refugee crises, border conflicts and economic marginalisation. The India-Pakistan LoC and India-China LAC show how frozen or disputed boundaries can become sites of military tension; refugee movements of Rohingyas, Afghans and Sri Lankans show exclusionary pressure; restricted-area rules and weak border trade can marginalise frontier communities. Exclusion can create internal borders, visa regimes and economic enclaves.

Mega-cities and global hierarchy. A small number of mega-cities organise global economics and culture because they host command and control functions: finance, law, headquarters, R&D, media and advanced producer services. Friedmann’s world-city hypothesis and Sassen’s analysis show that global cities are not merely large; they are nodes in a hierarchical network, with a few dominant cities and many regional satellites. GaWC rankings, based on advanced business-service connectivity, identify such nodes. These cities also spread global cultural forms—brands, media, fashion, food and language—producing a degree of global cultural homogenization, though local hybridization remains. In India, Mumbai and Delhi occupy significant positions in the global urban hierarchy: Mumbai through finance, port, film and services, Delhi through political-administrative and service functions. Their networks link smaller Indian cities to global flows.

Thus, formal regional delimitation, boundary politics and world-city hierarchies are interconnected. Regions provide the units for planning and governance; borders regulate inclusion and exclusion; mega-cities concentrate command functions. A feasible way forward is to use objective indicators and GIS/statistical methods for formal regions, pair boundary governance with inclusive resource and citizenship policies, and integrate Indian mega-cities into global networks while reducing regional imbalances.
