Key concepts
UrbanisationIncreasing proportion of population living in cities; 56% globally in 2020, projected 68% by 2050.
MegacityUrban area with 10 million+ inhabitants; over 33 worldwide; mostly in NICs (Tokyo, Delhi, Shanghai, Sao Paulo).
Push and Pull FactorsPush: rural poverty, lack of jobs, drought; pull: employment, education, healthcare, services; drives rural-urban migration.
Rio de JaneiroBrazilian megacity (13 million) with extreme inequality; wealthy beachside districts (Ipanema) and favelas like Rocinha.
Favela Bairro ProjectRio scheme upgrading favelas: paved roads, sewers, schools; improved conditions for 250,000 people.
Lagos NigeriaAfrica's largest city (15 million); rapid growth, traffic gridlock; Eko Atlantic land-reclamation project responds.

Common mistakes to avoid
Questions where students often pick the tempting wrong answer — make sure you know the right one:
Why do informal settlements develop in rapidly growing LIC cities?✗ People live in slums because they prefer them or are too lazy to find better housing. ✓ Rural-urban migration outpaces formal housing supply; migrants build their own homes on marginal land without secure land tenure — driven by housing shortage, not by personal choice.
Why do people move from rural to urban areas in LICs?✗ Because cities in poor countries are always better than the countryside. ✓ A combination of push factors (rural poverty, lack of services, agricultural change) and pull factors (perceived jobs, education, healthcare) — though reality often disappoints.
Why are urbanisation rates currently higher in LICs than HICs?✗ LICs have higher urbanisation rates because they have more cities than HICs. ✓ HICs urbanised earlier and are now near saturation (80%+ urban); LICs are still in the rapid urbanisation phase, with high rural-urban migration and urban natural increase.
Why do TNCs locate production in LICs?✗ Because TNCs want to develop poorer countries and lift them out of poverty. ✓ Lower labour costs, weaker regulation, access to raw materials, large potential markets, and government incentives like tax breaks in special economic zones.
What drives the movement of tectonic plates?✗ The Earth's rotation makes the plates move. ✓ Convection currents in the mantle combined with slab pull at subduction zones and ridge push at constructive boundaries.
