7. Causes of slums
• Rapid Industrialization: Industrial growth and
employment opportunities in towns and cities have acted
as powerful magnets to attract the rural population.
• Population Growth: If the town is not divided into
suitable zones and development is allowed to take place
in a haphazard manner, the slums may be created.
• Lack of zoning: When decentralization takes places,
the rich and middle class people move out to the
extended portions of the town and thus, the poor people
are left unattended in the overcrowded part of the town.
• Decentralization: The main cause of slum formation
can be described in one word as poverty.
7Prof. Ashish Makwana

8. • Poverty: The main cause of slum formation can be
described in one word as poverty. For labours and poor
people, it is difficult to pay heavy rent for decent living.
They therefore move in slum areas
• Education: If the inhabitants are lacking in education,
they may be easily dragged into social evils without any
attention to improvement of living conditions.
• Repair and maintenance: If cheap houses, constructed
by the land owner for the purpose of collecting rents, are
not properly maintained, these houses remain in a state
of decay to favour the formation of slums.
• Power of local authority: If the local authority
concerned does not possess adequate powers to control
the development of town, the slums may be formed.

9. Characteristics of slums
Appearance Fire hazards
Health and
sanitation
Income criteria
Overcrowding Morals Social isolation
9Prof. Ashish Makwana

10. • Appearance: This is rather the universal mark of the
slum and its unpleasant appearance offends the eyes,
nose and conscience. The structures appear to be
deteriorated and to be of over-age.
• Fire hazards: The slum area is often exposed to fire
accidents and consequent damages. One stick of
matches may prove to be sufficient to reduce the whole
slum to ashes in no time.
• Health and sanitation: The slum is characterized by low
standards of sanitation. It also refers an area of high
sickness and death rates.
Characteristics of slums
10Prof. Ashish Makwana

11. • Income criteria: The slum is a poverty area and it is
occupied by people of the lowest income group of the
society.
• Overcrowding: The slum is overcrowded with buildings
or the buildings are overcrowded with people or both
conditions prevail in the slum.
• Morals: The socially disorganized slum may prove to be
an area of delinquency, crime and vice.
• Social isolation: The slum area is of the lowest social
status and it is usually linked up with the rest of the
community through its labour force.

slums are easily vulnerable to by various diseases.
• Lack of amenities: Adequate public facilities like water
supply, drainage, sanitation, electricity etc. do not exist.
• Surrounding locality: Location of institutions like school,
hospital, library nearby the slums seriously affect their

14. Slum clearance
• Slum clearance may be defined as the complete removal
of slum area from the city. In this process the slum
dwellers are rehabilitated.
OBJECTIVES
• To improve living standards of people of the slum area
• To provide essential amenities like clean drinking water,
sanitation, clean surrounding and hygienic conditions for
healthy living.
• To prevent spread of epidemic in the town.
• To bring down social disparity among the various classes
of people To improve the aesthetic of a town.
14Prof. Ashish Makwana

15. Difficulties in slum clearance
• Lack of resources
• High cost of alternative sites near place of work
• Unwillingness of the slum dwellers to move from slum
area to new colonies
• Lengthy and time consuming procedures of acquisition
of slum area
• Low rent paying capacity of slum dwellers
15Prof. Ashish Makwana

16. Methods of slum clearance
1. Improvement method
• This method is adopted where slums are due to poor
drainage system and unhealthy conditions. Hence the
drainage arrangement is modified and improved. Public
utility services like water, drainage, gas, electricity may
be provided in the slum area.
2. Complete removal method
• In this method, the slum area is completely cleaned out
of the existing locality. All the dilapilated structures are
demolished. Only such buildings which are really in good
conditions are retained.

17. Prevention of slum formation
• Cheap housing
• Construction of buildings
• Compulsion of employers
• Rent restriction
• Maintenance and repairs
• Social education
