What makes cities grow?
Urban growth is caused by:
· Natural population growth (an excess of births over deaths)
· Net migration (an excess of inward migration from rural areas to cities)
People move to the city for a variety of reason:
· job opportunities
· earning money to send back home
· shortages of land, food and opportunities in the rural areas
· freedom from tradition
· the pull of the bright lights
· war, natural disease etc in rural areas
· hopeful they will receive support from the state or NGOs
Birth rates usually fall in the city because:
· education levels are higher (especially for girls and women)
· children are less economically advantaged in the cities and are expensive to
feed, clothe and shelter
· large families can be a drag on the economic progress
· no extended family structures to help with childcare
Death rates in cities are affected by:
· the quality of housing ­ often poor when growth is rapid but often improving
· quality of water supply
· quality of sewage treatment and disposal
· food supply
· health care
All factors above depend on wealth and there are often huge ranges of income, wealth
and access to services in cities, especially in the fastest growing cities.
