  24. 24. Mumbai:Back ground Problems:• 14,350,000 population• Indian Financial Centre and the centre ofBollywood• Population due to read 26 million by 2025Growth problems facing Mumbai• New migrants are coming in everyday wanting ashare of the new wealth• The port has enable India to become a exporter• Most of the migrants are uneducated andtherefore are not needed in a modern city• It has caused urban sprawl (cheap and poorlybuilt)• Massive overcrowding• Development of squatter settlements likeDharavi• The Mumbai Suburban Railway, created in 1853,links Mumbai to rest of India which is good forbusiness and trade making it the best way oftransport in Mumbai (7million/year).

  27. 27. Suburbanisation: (7)Why people moved:• Home to TV and film industry, so workers havehigher paid jobs• Higher disposable incomes means that carownership increases so commute to work• Other services locate here as people can affordto use the service• Higher incomes means people want largerhouses with gardens and garages for family• Increased I.T technology allows people to workfrom home• Only 7.8% in Beverly Hills do not own cars• Certain races forced out due to migration ofanother race causes suburbanisation• E.g. Compton is a poorer district where 28% donot own cars, populated with Hispanics.• When the Hispanic people moved intoCompton, the previous race, of white ethnicbackground moved out. Causes LA to spreadfurther out = Urban sprawl•• Case Study: Los Angeles, USA:• Located south California, West USA• 3.8 million people in 2006• Young unskilled workers attracted to thearea due to Hollywood and Beverly Hills,film and TV industry• Effects: the movement of people andexcessive amounts of suburbanisationcauses urban sprawl.• Problems:• More congestion of cars travelling inner city• Pollution :air, noise, visual• Higher crime rates in poorer districts e.g.Compton• Shortage of houses• Urban sprawl, loss of rural areas, countryside and villages.
