As Urban populations grow there is increased demand
for space e.g housing, resources and services. If these
increased demands cannot be met, it can lead to poor
quality of life for the people living in the area.
Many developing countries cannot afford these extra
demands or cannot keep up with the rapid rate of
urbanisation, so has a number of negative impacts:
· Not enough houses, cannot afford to rent or buy · Built on lands unsuitable for construction
· Forced to live in shelters or on streets e.g in 2009 · Lack of basic services e.g clean water and waste

· Build own homes, leads to slums of shanty towns, · Little education = hard to get a well paid job
poorly built. · Difference in wealth causes tension and social issues
· High competition for good jobs in formal sector, so such as violence and crime
migrants accept poorly paid jobs in informal sector
· Increases pressure on roads and railways causing
congestion and air pollution.…read more
