Urbanization involves a physical change in
which increasing proportions of populations
live in urban settings.

The movement of people to cities is one of
the dominant characteristics of population
change of 21st centuries.
Growing urbanization is a recent phenomenon in
developing countries.

➢ In India, the level of urbanization increased from
27.81% in 2001 Census to 31.16% in 2011 Census.

➢ The urban population in India is 377.1 million in
2011, with increase of 91 million from 2001 census.

➢ Urbanization a constant growing phenomenon of
increasing populations living in cities found to be
more in low-income countries.
Increase in urban population is determined by three

1.Natural increase (through birth).

2. Rapid migration from rural to urban, for better
employment opportunities, attraction of better
living & availability of social services like education,
health, transport entertainment etc.

3. Inclusion of new areas under ‘Urban’
Environmental health impacts associated
with rapid urbanization :

The effect on health of urbanization is two edged.
On the one hand, there are the benefits of ready
access to healthcare, sanitation,& secure nutrition
whilst on the other urban health hazards & risks
are substandard housing, over crowding, air
pollution, insufficient or contaminated drinking
water, inadequate sanitation, solid waste disposal
services, vector borne diseases, industrial waste,
increased motor vehicle traffic, stress associated
with poverty & unemployment etc.
The factors which influence the health status lieboth
within the individual itself & externally.

1.Substandard housing & over crowding :
Due to low Socio-economic Status the housing cond. is very
Over crowing refers where more people are living within a
single dwelling where movement is restricted,privacy
secluded, hygiene impossible,rest & sleep difficult.
In general over crowding will lead to rapid spread of
infectious diseases especially resp. infections such as
T.B, influenza, Diphtheriaetc.

2.Inadequate sewage & garbage disposal: Lead to fly
3. Contaminated water : water borne diseases
are more common like Diarrhoea, typhoid,
Cholera etc.

4. Vector borne diseases :This is found to be more
common in poor people living in urban area like
malaria, filaria, Plague, Dengue, Scabies etc.

5. Air pollution :1.3 billion urban residents world
wide are exposed to air pollution level above
recommended limit. The effects are immediate&
a. Immediate effects : Acute bronchitis.
b. Delayed effects : Chr. Bronchitis, lung cancer,
bronchial asthma, Emphysema& resp.

6. Motor vehicle accidents:
➢ Are more common among all fatal accidents
found in urban areas.
➢ Industrial accidents are also occur with
increasing frequency because of untrained
workers from the urban setup.
7. Psycho-somatic disorders:
➢Due to poverty & unemployment stress
associated disorders are more common
among the urban people residing in shanty

➢Duodenal ulcer, Bronchial asthma,
Hypertension, coronary heart disease, mental
disorders, Social deviant behavior (Suicide,
crime, violence & drug abuse).
Global urbanization & impact on health :

➢ Rapid urban & industrial growth is an important
parallel socio demographic phenomenon. Nearly
half of the world’s population lives in urban

➢ For better employment, education, healthcare
the more and more people are attracting towards

➢ However rapid & unplanned urban growth is
often associated with poverty, environmental
degradation & population demands that outstrips
service capacity.
➢ In 1950, less than 30% of the world’s population
lived in cities. This number grew to 47% in the
year 2000 (2.8 billion people), and it is expected
to grow to 60% by the year 2025.

➢ The no. of people living in slums & shanty towns
represents about 1/3 of people living in urban

➢ In less developed countries urbanization also
opens the door to ‘western diseases’ likeHTN,
CHD, obesity, diabetes, & asthma.
There are certain schemes introduced for urban

➢ National Urban Health Mission(NUHM)

➢ AMRUT – Atal mission for rejuvenation and urban

➢ JawaharlalNehru National Urban Renewal mission
