Demography is the study of human populations and how they change over time due to births, deaths, and migration. For city planners, demographic information from censuses is essential for planning housing, schools, hospitals, transportation, and other infrastructure needs. Population size, density, age distribution, and migration patterns affect what facilities a city requires. Planners must understand population characteristics to adequately plan utilities, amenities, and services for an area's residents. Demographic data helps identify the demand for healthcare, schools, parks and other resources based on a population's size, density, and age profile.

2. Demo stands for “People” and Graphy is
the “Study/ Writing”.
Basically Demography is the study of human
population; their size, composition, and
distribution across space and the process
through which populations change.
Birth, Death and Migration are the “ BIG
THREE ” of Demography.

4. Demographic Process observes intimately
the structure, size and distribution of the
population by the above five studies.
SIZE – It is the number of persons in the
population.
STRUCTURE – Distribution of population
among its sex and age groupings.
DISTRIBUTION – The arrangement of the
population in space at a given time.

5. For planners, census information is used
in just about all planning decisions.
Census provides information like age, sex
distribution, household composition their size
etc.
The census of housing allows planners to
access changes in the quality of housing and
related facilities and plan for future housing
needs.
From Census, we get some vital aspects
of demography, which are essential elements
for planning a city.

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
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
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

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.

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 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

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