The total fertility rate in an economy is defined as :

Result
Your answer:  ·  Correct: D
Explanation

The total fertility rate is defined as the average number of children born to each woman over the course of her life.[3] More precisely, it represents the average number of children that would be born to a woman over her lifetime if she were to experience the current age-specific fertility rates throughout her lifetime.[4] This makes option D correct, as it accurately captures the concept of TFR as the average number of live births a woman would have by the end of her child-bearing age.

Option A is incorrect because it describes the crude birth rate, which is the number of births over a given period divided by the person-years lived by the population, expressed as births per 1000 population.[5] Option B is incorrect as TFR measures births per woman, not per couple. Option C is incorrect because the birth rate and fertility rate are linked but distinct concepts[6], and TFR is not calculated as birth rate minus death rate—that would represent natural population growth.

This is a classic 'Sitter' question derived directly from static NCERT Human Geography and standard Economy texts. It tests fundamental clarity on demographic definitions. If you confused 'per 1000 people' (Crude Birth Rate) with 'per woman' (TFR), your static revision needs immediate tightening.

How this question is built

This question can be broken into the following sub-statements. Tap a statement sentence to jump into its detailed analysis.

Statement 1
Is the total fertility rate (TFR) defined as the number of children born per 1000 people in the population in a year?
Origin: Web / Current Affairs Fairness: CA heavy Web-answerable

Web source
Presence: 5/5
"Fertility rate – the total fertility rate is the average number of children born to each woman over the course of her life."
Why this source?
  • Directly defines the total fertility rate (TFR) as the average number of children born to each woman over her life.
  • Explicitly contrasts TFR with crude birth rate, indicating TFR is not measured per 1000 population per year.
Web source
Presence: 5/5
"the crude birth rate is the number of births over a given period divided by the person-years lived by the population over that period. It is expressed as the number of births per 1000 population."
Why this source?
  • Defines the metric that matches the user's wording: births per 1000 population is the crude birth rate, not TFR.
  • Shows that 'number of births per 1000 population' is a distinct concept from TFR.
Web source
Presence: 4/5
"the total fertility rate was highest in countries in Africa and central Asia, where most countries had a total fertility rate between 3 to 7 births per woman"
Why this source?
  • Describes TFR in units of births per woman (e.g., 'between 3 to 7 births per woman'), reinforcing that TFR is per woman, not per 1000 people per year.
  • Notes TFR is births per woman and relates to surviving children per woman, further confirming the per-woman basis.

Indian Economy, Vivek Singh (7th ed. 2023-24) > Chapter 8: Inclusive growth and issues > Recent demographic trends > p. 258
Strength: 5/5
“• Total Fertility Rate (TFR) is defined as the total number of children that would be born to each woman if she were to live to the end of her child-bearing years.• Replacement level fertility (RLF) is the level of fertility at which a population exactly replaces itself from one generation to the next. Ideally it should be 2.0 but generally it is 2.1 all over the world as we cannot expect all the female children will survive till the child bearing ages.• As per the latest National Family Health Survey (NFHS), India's TFR has declined to 2.0 which is below the replacement level fertility.”
Why relevant

Gives an explicit definition of TFR as the total number of children that would be born to each woman over her child-bearing years (per woman, lifetime measure).

How to extend

A student can contrast this per-woman lifetime definition with measures expressed 'per 1000 people in a year' to suspect they are different concepts.

Indian Economy, Nitin Singhania .(ed 2nd 2021-22) > Chapter 19: Population and Demographic Dividend > Is legislation on population regulation really required in the current scenario? > p. 570
Strength: 5/5
“Replacement level fertility rate is approximately 2.1 children per woman for most countries. TFR: It is the average number of children born per woman.”
Why relevant

States TFR is the average number of children born per woman and notes replacement level ~2.1 children per woman (units are 'per woman').

How to extend

A student can use the clear 'per woman' phrasing to rule out an interpretation that TFR is a per-1000-per-year rate.

FUNDAMENTALS OF HUMAN GEOGRAPHY, CLASS XII (NCERT 2025 ed.) > Chapter 2: The World Population Distribution, Density and Growth > Components of Population Change > p. 9
Strength: 5/5
“There are three components of population change – births, deaths and migration. The crude birth rate (CBR) is expressed as number of live births in a year per thousand of population. It is calculated as: Here, CBR = Crude Birth Rate; B = live births during the year; P= Estimated mid year population of the area. Death rate plays an active role in population change. Population growth occurs not only by increasing births rate but also due to decreasing death rate. Crude Death Rate (CDR) is a simple method of measuring mortality of any area. CDR is expressed in terms of number of deaths in a particular year per thousand of population in a particular region.”
Why relevant

Defines the crude birth rate (CBR) as the number of live births in a year per thousand of population — an example of a rate expressed 'per 1000 people in a year'.

How to extend

A student can map the 'per 1000 per year' formulation here to the statement's wording and infer that that formulation corresponds to CBR, not TFR.

CONTEMPORARY INDIA-I ,Geography, Class IX . NCERT(Revised ed 2025) > Chapter 6: Population > Processes of Population Change/Growth > p. 52
Strength: 4/5
“There are three main processes of change of population : birth rates, death rates and migration. The natural increase of population is the difference between birth rates and death rates. Birth rate is the number of live births per thousand persons in a year. It is a major component of growth because in India, birth rates have always been higher than death rates.”
Why relevant

Also defines birth rate as number of live births per thousand persons in a year and contrasts birth/death rates as components of population change.

How to extend

A student can use this to understand standard demographic convention: annual 'per 1000' measures are crude rates, distinct from lifetime-per-woman measures like TFR.

Why relevant

Provides historical series of birth and death rates expressed 'per 1000 persons' showing common use of 'per 1000 per year' for crude rates.

How to extend

A student can generalize that demographic statistics use 'per 1000 per year' wording for crude rates (CBR/CDR), supporting the idea that TFR (per woman) is different.

Statement 2
Is the total fertility rate (TFR) defined as the number of children born to a couple in their lifetime in a given population?
Origin: Web / Current Affairs Fairness: CA heavy Web-answerable

Web source
Presence: 5/5
"Fertility rate – the total fertility rate is the average number of children born to each woman over the course of her life."
Why this source?
  • Explicitly defines TFR as an average per woman, not per couple.
  • Specifies that the measure covers children born 'over the course of her life', i.e. lifetime.
Web source

"The total fertility rate (TFR) of a population is the average number of children that are born to a woman over her lifetime,"
Why this source?
  • Defines TFR as the average number of children born to a woman over her lifetime.

Web source
Presence: 5/5
"Note: The total fertility rate (TFR) of a population is the average number of children that would be born to a woman over her lifetime if she were to experience the current age-specific fertility rates throughout her lifetime."
Why this source?
  • Restates that TFR is the average number of children that would be born to a woman over her lifetime.
  • Mentions the role of age-specific fertility rates, reinforcing the standard demographic definition (per woman).

Strength: 5/5
“• Total Fertility Rate (TFR) is defined as the total number of children that would be born to each woman if she were to live to the end of her child-bearing years.• Replacement level fertility (RLF) is the level of fertility at which a population exactly replaces itself from one generation to the next.

Why relevant

Gives a direct definition-style formulation: TFR is the total number of children that would be born to each woman if she were to live to the end of her child-bearing years.

How to extend

A student can contrast 'per woman' here with the statement's 'per couple' language and use basic reasoning to suspect the statement misstates the unit (woman vs couple).

Indian Economy, Nitin Singhania .(ed 2nd 2021-22) > Chapter 19: Population and Demographic Dividend > Is legislation on population regulation really required in the current scenario? > p. 570
Strength: 5/5
“Replacement level fertility rate is approximately 2.1 children per woman for most countries. TFR: It is the average number of children born per woman.”
Why relevant

States TFR as 'the average number of children born per woman' and mentions replacement level ~2.1 children per woman.

How to extend

Compare the unit 'per woman' to 'per couple' in the statement; knowing replacement level refers to women helps reject the 'per couple' phrasing.

Indian Economy, Nitin Singhania .(ed 2nd 2021-22) > Chapter 19: Population and Demographic Dividend > Family Planning in the 1990s > p. 568
Strength: 4/5
“• viii. Classification of objectives as short-term, medium-term and long term goals. For example: • Immediate objective was to improve the reproductive health and child care. (a) • Medium-term goal was to keep the Total Fertility Rate (TFR) at 2.1 children per woman. • Long-term objective was population stabilisation by 2045. (c)”
Why relevant

Uses policy language targeting TFR 'at 2.1 children per woman' as a medium-term goal, reinforcing the 'per woman' metric.

How to extend

A student can infer that official demographic targets treat TFR per woman, so interpreting it per couple would require an extra conversion/assumption about couples.

Geography of India ,Majid Husain, (McGrawHill 9th ed.) > Chapter 13: Cultural Setting > The National Population Policy, 2000 > p. 115
Strength: 4/5
“The immediate objective of the National Population Policy, 2000, was to address the unmet needs for contraception, health care infrastructure and to provide integrated service delivery system for the basic reproductive and child health care. The medium objective was to bring the Total Fertility Rate (TFR) to replacement level (2.1) by 2010 through vigorous implementation of inter-sectoral operation strategies. The long-term objective is to achieve a zero growth rate of population by 2045 at a level consistent with the requirements of sustainable economic growth, social development, and environmental protection. The National Population Policy, 2000 stressed on the following points to reduce the fertility rate and to restrict the growth of population at the level of replacement: • 1.”
Why relevant

National policy objective framed as bringing the Total Fertility Rate to replacement level (2.1) by a date, again linking TFR with children per woman.

How to extend

Knowing replacement-level fertility is expressed per woman allows a student to question the statement's 'per couple' phrasing and consider demographic conventions.

Indian Economy, Nitin Singhania .(ed 2nd 2021-22) > Chapter 19: Population and Demographic Dividend > Is legislation on population regulation really required in the current scenario? > p. 569
Strength: 3/5
“• Yes: According to a report, by 2027, India will probably become the most populous country in the world.; However, critics argue that: The Total Fertility Rate (TFR) of India is declining. Moreover, the TFR at replacement level was targeted as 2.1 and according to National Family Health Survey data, current TFR is 2.16 (just above the targeted value). The TFR cannot be revived once it declines. • Yes: Proportion of marriageable age group is higher and hence population will continue to grow.”
Why relevant

Mentions TFR values and replacement level in discussion of population trends, treating TFR as an aggregate per-woman indicator in demographic analysis.

How to extend

A student could use these examples of TFR figures (expressed per woman) to show that demographic practice reports TFR per woman, not per couple.

Statement 3
Is the total fertility rate (TFR) defined as the birth rate minus the death rate?
Origin: Web / Current Affairs Fairness: CA heavy Web-answerable

Web source
Presence: 5/5
"Fertility rate – the total fertility rate is the average number of children born to each woman over the course of her life."
Why this source?
  • Explicitly defines the total fertility rate as an average number of children born to each woman over her life.
  • This definition describes lifetime children per woman, not a calculation involving birth rate minus death rate.
Web source
Presence: 5/5
"The total fertility rate (TFR) of a population is the average number of children that are born to a woman over her lifetime, if they were to experience the exact current age-specific fertility rates (ASFRs) through their lifetime..."
Why this source?
  • States the TFR is the average number of children born to a woman over her lifetime under current age-specific fertility rates.
  • That formulation indicates TFR is a fertility measure per woman, not the difference between birth and death rates.
Web source
Presence: 4/5
"number of children a woman would bear during her lifetime if she were to experience the current age-specific fertility rates throughout her childbearing years. ... The birth rate and fertility rate are linked but distinct, as fertility considers the patterns within a population over time while the birth rate measures births within a specific timeframe."
Why this source?
  • Defines TFR as the number of children a woman would bear during her lifetime given current age-specific fertility rates.
  • Adds that birth rate and fertility rate are 'linked but distinct', indicating they are different concepts.

Why relevant

Gives a direct definition of Total Fertility Rate (TFR) as the total number of children a woman would bear over her child‑bearing years (not a rate difference).

How to extend

A student could contrast this definition with measures expressed per 1000 (birth/death rates) to see they are different kinds of measures and thus suspect the statement is false.

“There are three main processes of change of population : birth rates, death rates and migration. The natural increase of population is the difference between birth rates and death rates. Birth rate is the number of live births per thousand persons in a year. It is a major component of growth because in India, birth rates have always been higher than death rates.”
Why relevant

States that 'natural increase of population is the difference between birth rates and death rates' — showing that birth minus death is used to measure natural population change, not fertility per woman.

How to extend

Combine this with the TFR definition (snippet 1) to infer that birth‑minus‑death relates to population growth, not to TFR.

FUNDAMENTALS OF HUMAN GEOGRAPHY, CLASS XII (NCERT 2025 ed.) > Chapter 2: The World Population Distribution, Density and Growth > Components of Population Change > p. 9
Strength: 4/5
“There are three components of population change – births, deaths and migration. The crude birth rate (CBR) is expressed as number of live births in a year per thousand of population. It is calculated as: Here, CBR = Crude Birth Rate; B = live births during the year; P= Estimated mid year population of the area. Death rate plays an active role in population change. Population growth occurs not only by increasing births rate but also due to decreasing death rate. Crude Death Rate (CDR) is a simple method of measuring mortality of any area. CDR is expressed in terms of number of deaths in a particular year per thousand of population in a particular region.”
Why relevant

Explains components of population change and defines Crude Birth Rate (CBR) and Crude Death Rate (CDR) as births/deaths per thousand — a different metric class from TFR.

How to extend

Using a world map or population data, a student could compare CBR−CDR values with TFR values to see they behave differently, reinforcing that TFR ≠ birth−death.

Strength: 4/5
“India—Birth Rate, Death Rate, and Natural Growth Rate of Population (1911–2011) • Census Year: 1911; Crude Birth Rate: 49; Crude Death Rate: 43; Natural Growth Persons Per Thousand of Population: 6 • Census Year: 1921; Crude Birth Rate: 48; Crude Death Rate: 47; Natural Growth Persons Per Thousand of Population: 1 • Census Year: 1931; Crude Birth Rate: 46; Crude Death Rate: 36; Natural Growth Persons Per Thousand of Population: 10 • Census Year: 1941; Crude Birth Rate: 45; Crude Death Rate: 31; Natural Growth Persons Per Thousand of Population: 14 • Census Year: 1951; Crude Birth Rate: 40; Crude Death Rate: 27; Natural Growth Persons Per Thousand of Population: 13 • Census Year: 1961; Crude Birth Rate: 42; Crude Death Rate: 23; Natural Growth Persons Per Thousand of Population: 19 • Census Year: 1971; Crude Birth Rate: 37; Crude Death Rate: 15; Natural Growth Persons Per Thousand of Population: 22 • Census Year: 1981; Crude Birth Rate: 34; Crude Death Rate: 12; Natural Growth Persons Per Thousand of Population: 22”
Why relevant

Table listing Crude Birth Rate, Crude Death Rate and 'Natural Growth' (persons per thousand) explicitly treats natural growth as the difference between CBR and CDR.

How to extend

A student could note that natural growth (CBR−CDR) is reported per thousand population, whereas TFR (snippet 1) is children per woman — different units imply different concepts.

Total Fertility Rate Decreased from (per 1000) 4.50 in 1981 to 2.4 in 2011• 4.”
Why relevant

Lists TFR among health indicators and (in the list) appears alongside CBR and CDR, implying TFR is a distinct demographic indicator rather than a computed difference of birth and death rates.

How to extend

Recognizing TFR as a separate indicator, a student could look up unit conventions or example values to confirm TFR is not simply birth rate minus death rate.

Why this source?
  • Refers to TFR in units of 'children per woman' (e.g., target of 2.1), reinforcing that TFR is measured per woman across reproductive life.
  • Contextual use of 'children per woman' supports the interpretation of TFR as an average births-per-woman metric.
Pattern takeaway: UPSC consistently asks 'Definition' questions in Economy/Geography where the wrong options are actually correct definitions of *other* related terms. You must study comparative tables of metrics (e.g., CPI vs WPI, TFR vs CBR) rather than isolated definitions.
How you should have studied
  1. [THE VERDICT]: Sitter. Directly solvable from NCERT Class XII Human Geography (Ch 2) or Vivek Singh/Singhania Economy chapters on Demography.
  2. [THE CONCEPTUAL TRIGGER]: Demography & Vital Statistics. The specific confusion matrix between TFR, CBR (Crude Birth Rate), and Natural Growth Rate.
  3. [THE HORIZONTAL EXPANSION]: Memorize the Denominators: TFR (per woman), CBR/CDR (per 1,000 population), IMR (per 1,000 live births), MMR (per 1,00,000 live births). Know India's current TFR (2.0 as per NFHS-5) vs Replacement Level (2.1).
  4. [THE STRATEGIC METACOGNITION]: UPSC traps are often in the units. When reading definitions, isolate the 'Numerator' (Live births) and the 'Denominator' (Woman vs. 1000 people). Option A described CBR; Option C described Natural Increase. Only D described TFR.
Concept hooks from this question
📌 Adjacent topic to master
S1
👉 Total Fertility Rate (TFR) — per woman lifetime births
💡 The insight

TFR measures the average number of children a woman would bear over her entire child-bearing period.

High-yield for demographic questions because it distinguishes individual-level fertility from population-level rates; connects directly to population growth, demographic transition theory, and family‑planning policy targets; mastering this helps answer conceptual and data-interpretation questions about fertility.

Replacement-level fertility is the TFR at which a population exactly replaces itself from one generation to the next, typically around 2.1.

High-yield: frequently used in questions on population stabilization, demographic targets, and policy evaluation; connects TFR values to policy goals and demographic transition concepts.

👉 Components of population change: births, deaths, migration
💡 The insight

Births (and birth-rate measures) are primary drivers of population change that relate to fertility indicators like TFR.

High-yield: foundational for understanding population dynamics, framing questions on natural increase, and linking fertility measures with mortality and migration in policy discussions.

👉 Total Fertility Rate (TFR) — lifetime births per woman
💡 The insight

TFR measures the total number of children a woman would bear over her childbearing years, not a difference of rates.

High-yield for population questions: distinguishes a cohort/fertility measure (TFR) from annual vital rates. Helps answer questions on demographic indicators, fertility policy interpretation, and comparisons between fertility and growth measures.

🌑 The Hidden Trap

The 'Next Logical Question' is the difference between Gross Reproduction Rate (GRR) and Net Reproduction Rate (NRR). NRR accounts for female mortality before childbearing age ends (NRR < 1 means population will shrink eventually), whereas GRR assumes all daughters survive.

⚡ Elimination Cheat Code

Apply 'Unit Logic'. Fertility is biologically a capacity of the *woman*, not the general population (which includes men and children). Option A uses 'per 1000 people' (too broad). Option B uses 'couple' (social unit, variable). Option C is a math difference. Only Option D focuses on the biological unit ('woman') and the specific timeframe ('child-bearing age').

🔗 Mains Connection

Mains GS-1 (Population & Associated Issues): TFR falling below 2.1 (Replacement Level) signals the onset of an 'Aging Society'. This shifts the policy focus from Population Control (Family Planning) to Social Security (Silver Economy) and Labor Productivity (to offset shrinking workforce).
