This document discusses demography and family planning. It begins with introducing demography as the scientific study of human populations and tracing the history and development of demography as a field. It then outlines the demographic cycle that describes 5 stages of population growth that nations typically progress through. The document also summarizes current world population trends, including historical population milestones, projected future growth, and differences in birth and death rates and growth rates globally. In addition, it reviews key demographic indicators and trends in India, including population size, composition, density, vital rates like birth and death rates, and policy interventions. The document aims to provide an overview of demography and population dynamics globally and nationally.

⢠The word demography comes from two ancient greek words, demos,
meaning "the people," and graphy, meaning "writing about or
recording somethingâ
⢠Demography means "writing about the people."
⢠Like many branches of the sciences, demography began in the 19th
century, when the general craze for cataloging information about the
world really took off.

⢠In its simplest definition, demography is the
scientific study of human populations.

⢠Graunt also published an early version of the life
table which, having been further developed by
Edmund Halley and Joshua Milne, led to the
publication in 1840 of the first official life table
by William Farr, compiler of scientific abstracts in
the general register office for England and Wales.
⢠The statistical concepts of the life table remain
today the fundamental elements of demographic
methods.

⢠Demography relates to explanation of why and
when events occur to people.
⢠For example, Demography addresses questions
such as:
What explains long life?
What explains teenage pregnancy?
What explains early school drop-out?
What explains contracting a disease such as
hiv/aids?
What explains how long people live after
contracting a particular disease?
Why do people move from rural to urban areas? 16-02-2023 7

⢠Demography draws upon knowledge in other
disciplines to develop its theory.
⢠The main disciplines that contribute to
demographic theory are
Economics
Sociology
Anthropology
Epidemiology
Geography
Public health
Biology

⢠Theory in demography is established very largely
through comparative analysis:
⢠Comparisons across space and time and across
different sub-groups of the population.
⢠In this regard, demography is inherently
comparative.

Demography, as understood today, is the scientific study of human
population. it focuses its attention on three readily observable human
phenomena :
(a) changes in population size
(b) the composition of the population
(c) the distribution of population in space.

It deals with five "demographic processesâ namely:
Fertility
Mortality
Marriage
Migration
Social mobility.
These five processes are continuously at work within a population
determining size, composition and distribution.

13. DEMOGRAPHIC CYCLE
The history of world population since 1650 suggests that there is a
demographic cycle of 5 stages through which a nation passes:
(1) FIRST STAGE (HIGH STATIONARY)
(2) SECOND STAGE (EARLY EXPANDING)
(3) THIRD STAGE (LATE EXPANDING)
(4) FOURTH STAGE (LOW STATIONARY)
(5) FIFTH STAGE (DECLINING)
16-02-2023 13
14. DEMOGRAPHIC CYCLE
(1) FIRST STAGE (HIGH STATIONARY)
This stage is characterized by a high birth
rate and a high death rate which cancel
each other and the population remains
stationary.
India was in this stage till 1920.
16-02-2023 14
15. DEMOGRAPHIC CYCLE
(2) SECOND STAGE (EARLY EXPANDING)
⢠The death rate begins to decline, while
the birth rate remains unchanged
⢠Many countries in south asia, and africa
are in this phase.
16-02-2023 15
16. DEMOGRAPHIC CYCLE
(3) THIRD STAGE (LATE EXPANDING)
⢠The death rate declines still further,
and the birth rate tends to fall.
⢠The population continues to grow
because births exceed deaths.
⢠India has entered this phase.
⢠In a number of developing countries
(e.g., china, singapore) birth rates have
declined rapidly.
16-02-2023 16
17. DEMOGRAPHIC CYCLE
(4) FOURTH STAGE (LOW STATIONARY)
⢠This stage is characterized by a low
birth and low death rate with the result
that the population becomes stationary.
⢠Zero population growth has already
been recorded in Austria during 1980-
85.
16-02-2023 17
18. DEMOGRAPHIC CYCLE
(4) FOURTH STAGE (LOW STATIONARY)
⢠Growth rates as little as 0.1 were
recorded in UK, Denmark, Sweden and
Belgium during 1980-85.
⢠Most industrialized countries have
undergone a demographic transition
shifting from a high birth and high
death rates to low birth and low death
rates.
16-02-2023 18
19. DEMOGRAPHIC CYCLE
(5) FIFTH STAGE : (DECLINING)
⢠The population begins to decline
because birth rate is lower than the
death rate.
⢠Some east european countries, notably
Germany and Hungary are experiencing
this stage

⢠The growth rate is not uniform in the world.
⢠There are many countries in the world where the growth rate is less

⢠In developing countries, the growth rates are excessive - it is around
2.6 per cent in Africa, 1.1 per cent in Latin America, 0.3 per cent in
Europe and industrialized countries, and 1.3 per cent in Asia.
⢠A population growing at 0.5 per cent per year will double in about 140
years, a population growing at 3 per cent per year will double in about
20- 25 years These differences in growth rates are largely the result
of fertility and mortality patterns.

GROWTH RATES
The salient features of population growth at a glance are as follows:
⢠Approximately 95 per cent of this growth is occurring in the
developing countries.
⢠Currently, one-third of the world's population is under the age of 15,
and will soon enter the reproductive bracket, giving more potential for
population growth.
⢠The UNFPA estimates that world population is most likely to reach 10
billion people by 2050, and 20. 7 billion a century later. 16-02-2023 52

CONCLUSION
16-02-2023 54
⢠There are uncertainties in future population growth, not only because there are
uncertainties in the future trends in fertility, mortality, and migration, but also
because there are many other factors that could affect these trajectories.
⢠International consensus on climate change and ecosystem protections may trigger
population control policies, and the ongoing pandemic is likely to have some
impact on mortality, migration, or even fertility.

⢠By fertility is meant the actual bearing of
children.
⢠A woman's reproductive period is roughly
from 15 to 45 years - a period of 30
years.
⢠A woman married at 15 and living till 45
with her husband is exposed to the risk of
pregnancy for 30 years, and may give birth
to 15 children. but this maximum is rarely
achieved.

⢠Fertility depends upon several factors. The
higher fertility in India is attributed to
1. Universality Of Marriage
2. Lower Age At Marriage
3. Low Level Of Literacy
4. Poor Level Of Living
5. Limited Use Of Contraceptives
6. Traditional Ways Of Life.

1. Age at marriage
⢠The Registrar General of India collected data on
fertility on a national scale and found that
females who marry before the age of 18 gave
birth to a larger number of children than those
who married after.
⢠In India some demographers have estimated
that if marriages were postponed from the age
of 16 to 20-21. the number of births would
decrease by 20- 30 per cent

1. Age at marriage
⢠As early as 1929, the Sarada Act was enacted
forbidding the practice of child marriage.
⢠The census data reveals that prior to 1951 , the
average age at marriage for girls in India was
13 years.
⢠The Child Marriage Restraint Act of 1978 raises
the legal age at marriage from 15 to 18 years
for girls, and from 18 to 21 years for boys.

1. Age at marriage
⢠Studies indicate that in many States, the mean
age at marriage for girls has already moved
upto 20 years in 2006, and many others are
very close to this.
⢠For the year 2016, the national average for
effective marriage is 22.3 years.
⢠The exceptions are the rural areas, where a
substantial proportion of marriages continue to
take place when the girl is around 16 years of
age

2 . Duration of married life
⢠Studies indicate that 10-25 per cent of all
births occur within 1- 5 years of married life
⢠50-55 per cent of all births within 5-15 years
of married life.
⢠Births after 25 years of married life are very
few.
⢠This suggests that family planning efforts
should be concentrated in the first few years of
married life in order to achieve tangible results.

3 . Spacing of children
⢠Studies have shown that when all births are
postponed by one year, in each age group,
there was a decline in total fertility.
⢠It follows that spacing of children may have a
significant impact on the general reduction in
the fertility rates.

that the total fertility rate is 1.07 children
higher for illiterate women than for women with
at least a high school education

5 . Economic status
⢠Operational Research studies support the hypothesis that
economic status bears an inverse relationship with fertility.
⢠The total number of children born declines with an increase
in per capita expenditure of the household.
⢠The World Population Conference at Bucharest in fact
stressed that economic development is the best
contraceptive.
⢠It will take care of population growth and bring about
reductions in fertility.

⢠The National Family Health Survey- 4 reported a total
fertility rate of 2.61 among Muslims as compared to 2.13
among Hindus.
⢠The total fertility rate among Christians was found to be
1.99.
⢠Among Hindus, the lower castes seem to have a higher
fertility rate than the higher castes

7 . Nutrition
⢠There appears to be some relationship between nutritional
status and fertility levels.
⢠Virtually, all well-fed societies have low fertility, and
poorly-fed societies high fertility.
⢠The effect of nutrition on fertility is largely indirect.

8. Family planning
⢠Family planning is another important factor in fertility
reduction.
⢠In a number of developing countries, family planning has
been a key factor in declining fertility.
⢠Family planning programmes can be initiated rapidly and
require only limited resources, as compared to other
factors.

⢠Birth rate is the simplest indicator of
fertility and is defined as "the number of
live births per 1000 estimated mid-year
population, in a given year". It is given by
the formula :
⢠The birth rate is an unsatisfactory
measure of fe rtility because the total
population is not exposed to child
bearing. Therefore it does not give a true
idea of the fertility of a population.

2 . General Fertility Rate (GFR)
⢠It is the "number of live births per 1000
women in the reproductive age-group
(15- 44 or 49 years) in a given year".
⢠General fertility rate is a be tter measure
of fertility than the crude birth rate
because the denominator is restricted to
the number of women in the child-
bearing age, rather than the whole
population.
⢠The major weakness of this rate is that
not all women in the denominator a re

It is said that population growth rates, like railway trains, are subject to momentum. They start slowly and gain momentum. Once in motion, it takes time to bring the momentum under control. In case of the train the control factors are mass and inertia; in population, they are age distribution , marriage customs and numerous cultural, social and economic factors.

The dependency ratio can be subdivided into young age dependency ratio (0-14 years); and old age dependency ratio (65 years and more).

For international comparison, the child, old and total dependency ratios are used to study the dependency burden of the population.
The term "demographic bonus" connotes the period when the dependency ratio in a population declines because of decline in fertility, until it starts to rise again because of increasing longevity.
