Analysing urbanisation requires distinguishing urbanisation rate (the percentage shift toward urban areas) from urban growth (absolute numbers). Use the HDE/EME/LDE framework to compare patterns: HDEs show slow or declining rates; EMEs show rapid growth in key hub cities; LDEs show the fastest rates.
World population doubled between 1950 and 2015, but urban population trebled. In 1945, less than one-third of people lived in urban areas. The decline of industry in HDEs—relocating to EMEs and LDEs for cheaper labour—drove industrial growth in emerging economies, pulling rural dwellers toward cities.
Key hub cities include Shanghai, Mumbai, Lagos, and São Paulo. Asia is expected to account for 60% of global urban growth by 2030. Finance, electronics, and manufacturing concentrate in these cities, creating strong pull factors.
By 2030, 3 billion people will need adequate housing; 1.6 billion are predicted to live in slums. Megacities like Mumbai, Mexico City, and Tokyo concentrate problems: insufficient energy and water, and security only for those who can pay.
| Economy Type | Urbanisation Rate | Drivers | Examples |
|---|---|---|---|
| HDE | Slow or declining | Past Industrial Revolution; transport/communication enable dispersal; 'pushed' away from cores | North America, Europe |
| EME | Rapid | Key trade hubs; finance, electronics, manufacturing; Asia 60% of global growth by 2030 | Shanghai, Mumbai, Lagos, São Paulo |
| LDE | Fastest | Low-cost manufacturing; push-pull factors; high natural increase; most development in big cities | Africa, SE Asia |
Urbanisation (Stage 1): Settlements agglomerate, trading posts develop, inward migration and natural increase occur. Suburbanisation (Stage 2): People move to urban fringes, building densities fall, complex wealth-poverty patterns emerge.
Counter-urbanisation (Stage 3): Movement from urban to rural. Causes include deindustrialisation, car ownership, increased wealth, agricultural decline, green belt policies, and second-home demand. It can push house prices beyond locals' reach.
Re-urbanisation (Stage 4): Movement back into cities. Causes include job growth, allure of the '24-hour city', regeneration, improved air quality and safety, and rising commuter costs. Together these stages form the urban process timeline.
Confusing urbanisation with urban growth: Urbanisation is the percentage shift; urban growth is absolute numbers. A city can grow in population while urbanisation rates nationally decline if rural areas grow faster.
Treating all developing nations alike: EMEs and LDEs differ. EMEs have established manufacturing hubs; LDEs often have fastest rates but weakest infrastructure. Asia and Africa drive most future growth.
Ignoring the urban process timeline: Each stage (urbanisation, suburbanisation, counter-urbanisation, re-urbanisation) has distinct causes. Counter-urbanisation is not 'reverse urbanisation'—it describes movement to rural areas, not a decline in urban proportion globally.
Overlooking over-urbanisation: When urbanisation outpaces economic development, unemployment and slum growth result. This is common in LDEs and affects exam discussions of costs vs benefits.
Urbanisation connects to globalisation (trade, FDI, manufacturing relocation), demography (natural increase, age structure of migrants), and sustainability (energy, water, housing, slums). Megacity challenges in Mumbai or Lagos illustrate these intersections.
Regeneration and re-urbanisation link to economic cycles: deindustrialisation triggers counter-urbanisation; job growth and regeneration trigger re-urbanisation. Detroit's decline and London's resurgence exemplify these dynamics.
Consider inequality: cities concentrate both opportunity and deprivation. Security, housing, and services are often available only to those who can pay, creating spatial divides within urban areas.
Extension to climate and resilience: Urban areas face disproportionate exposure to heat islands, flooding, and resource scarcity. Future urbanisation must address sustainability and adaptive capacity.
