Answer: B
Explanation: ASFR calculates fertility for specific age groups such as 20–24 or 25–29 years.
6
Total Fertility Rate represents
A Number of daughters per woman
B Average number of children per woman
C Births per 1000 population
D Deaths per 1000 population
Answer: B
Explanation: TFR indicates the average number of children a woman would have during her lifetime.
7
Replacement level fertility is approximately
A 1.5
B 2.1
C 3.0
D 4.0
Answer: B
Explanation: A TFR of about 2.1 ensures population replacement without growth.
8
Gross Reproduction Rate refers to
A Number of sons per woman
B Number of daughters per woman
C Total population growth
D Male births only
Answer: B
Explanation: GRR measures the average number of daughters born to a woman.
9
Net Reproduction Rate differs from GRR because it considers
A Male births
B Female mortality
C Migration
D Marriage rate
Answer: B
Explanation: NRR includes female survival rate, while GRR assumes no mortality.
10
NRR equal to 1 indicates
A Declining population
B Stable population
C Rapid population growth
D Negative growth
Answer: B
Explanation: NRR = 1 means each generation replaces itself exactly.
11
Crude Death Rate is calculated per
A 100 population
B 1000 population
C 10,000 population
D 1 lakh population
Answer: B
Explanation: Mortality rates are generally expressed per 1000 population.
12
Infant Mortality Rate measures deaths of children
A Below 5 years
B Below 1 year
C Below 10 years
D Below 15 years
Answer: B
Explanation: IMR represents deaths of infants under age one per 1000 live births.
13
Maternal Mortality Ratio measures deaths of
A Women during pregnancy
B Infants under one year
C Elderly persons
D Children under five
Answer: A
Explanation: MMR refers to maternal deaths during pregnancy or childbirth per 100,000 births.
14
Age Specific Death Rate refers to
A Death rate for specific age group
B Total deaths in a country
C Infant deaths only
D Death rate of males only
Answer: A
Explanation: ASDR measures mortality for specific age groups such as 60–70 years.
15
Life expectancy is obtained from
A Birth register
B Life table
C Death certificate
D Population census
Answer: B
Explanation: Life tables provide life expectancy at different ages.
16
The most precise measure of fertility is
A CBR
B ASFR
C IMR
D CDR
Answer: B
Explanation: ASFR considers age variation in fertility.
17
Which measure ignores mortality
A GRR
B NRR
C IMR
D CDR
Answer: A
Explanation: GRR assumes all women survive through reproductive years.
18
A high Infant Mortality Rate indicates
A Good health system
B Poor health conditions
C Low birth rate
D Low fertility
Answer: B
Explanation: High IMR reflects poor healthcare and nutrition.
19
The main source of vital statistics in India is
A Sample surveys
B Civil Registration System
C Bank reports
D Agricultural census
Answer: B
Explanation: Birth and death data are collected through civil registration.
20
Total Fertility Rate is calculated from
A Death rates
B Age specific fertility rates
C Migration rates
D Marriage rates
Answer: B
Explanation: TFR is obtained by summing ASFR values across reproductive ages.

21
The demographic transition theory explains changes in
A Population growth patterns
B Rainfall patterns
C Trade patterns
D Industrial production
Answer: A
Explanation: The theory describes how birth and death rates change during development.
22
In developed countries the fertility rate is generally
A High
B Moderate
C Low
D Extremely high
Answer: C
Explanation: Developed nations usually have low fertility due to urbanization and education.
23
Which indicator measures population growth indirectly
A NRR
B Rainfall
C Crop yield
D Inflation
Answer: A
Explanation: NRR indicates replacement level of population.
24
The width of reproductive age intervals in TFR calculation is
A 3 years
B 5 years
C 10 years
D 15 years
Answer: B
Explanation: Age groups in fertility analysis are usually five-year intervals.
25
Life table analysis mainly studies
A Mortality pattern
B Fertility pattern
C Agricultural pattern
D Migration pattern
Answer: A

27
Population replacement occurs when
A NRR = 1
B NRR > 1
