6. POPULATION STUDY
It is evident that a larger
population will need more
business, more housing,
office, schools, health
centres, open spaces, and
other physical, social and
other physical, social and
recreational infrastructure.
Demographical study helps us to study the population and
their lifestyle; which helps to identify the need of utilities,
infrastructure, basic amenities according to the need of a specific
area for a specific population.

7. POPULATION DENSITY
Some times it is observed
that population density in a
study area is a big problem
rather than high population.
It is due to higher density
in a respectively smaller
in a respectively smaller
area with limited facilities.
Population density can grow and shrink a particular city,
and can result vertical or horizontal growth of that city.
Hence density study makes planners aware of the future of
a particular city and some problems like “Urban sprawl” can be
controlled by the study of population density.

9. Migration is also a root
cause of poverty which leads to
increase of slum areas which is
a very big issues in urban areas
today.

10. AGE PATTERN
Age pattern study is basically related with fertility,
mortality, infant mortality, marriage etc. and driven by natural,
environmental characters also.
This is also a very important for planning studies.

11. Demography also includes the
study of different age
categories.
The issues of aging is related
with different social, political
and financial issues.
Based on financial and economic view, a very important
Based on financial and economic view, a very important
issue is the demand, health and consumption pattern of elderly
people. This survey is mainly analyzed by marketing scientists,
health care sectors.
Example : Suppose a place contains relatively higher number of
elderly people. So during the area’s spatial plan, medical facilities
must be provided in quickly accessible distances in that area.

12. Likewise in an area where children are more in number,
must provides with parks, schools, playgrounds etc.
