The total fertility rate in an economy is defined as :
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.

PROVENANCE & STUDY PATTERN
Guest previewThis 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.
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?
- 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?
- Statement 3: Is the total fertility rate (TFR) defined as the birth rate minus the death rate?
- Statement 4: Is the total fertility rate (TFR) defined as the average number of live births a woman would have by the end of her child-bearing age?
- 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.
- 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.
- 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.
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).
A student can contrast this per-woman lifetime definition with measures expressed 'per 1000 people in a year' to suspect they are different concepts.
States TFR is the average number of children born per woman and notes replacement level ~2.1 children per woman (units are 'per woman').
A student can use the clear 'per woman' phrasing to rule out an interpretation that TFR is a per-1000-per-year rate.
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'.
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.
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.
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.
Provides historical series of birth and death rates expressed 'per 1000 persons' showing common use of 'per 1000 per year' for crude rates.
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.
