Context
India’s reported Total Fertility Rate of 1.9 in the United Nations Population Fund’s (UNFPA) State of World Population 2025 Report, below the replacement level of 2.1, has sparked debate over whether this figure truly reflects the country’s fertility reality or conceals methodological biases, as concerns shift from overpopulation to ageing, labour shortages, and economic slowdown.
What is Total Fertility Rate (TFR)?
- The Total Fertility Rate (TFR) is the average number of children a woman is expected to bear during her lifetime, assuming she experiences the current age-specific fertility rates (ASFRs) throughout her reproductive years (ages 15-49).
- In simple terms, TFR tells us how many children a woman would have if she lived through her reproductive life experiencing today’s fertility patterns.
Why is TFR Important?
The Total Fertility Rate (TFR) helps us understand how fast or slow a country’s population is growing. It is one of the most important indicators for planning development, economy, and social policies.
| Area | Why It Matters |
| Population Growth | TFR shows whether the population is increasing, stable, or shrinking. A TFR of about 2.1 keeps the population size stable (called replacement-level fertility). |
| Economic Planning | Helps the government plan for jobs, schools, housing, and pensions. Too low TFR means fewer workers in the future; too high TFR means pressure on resources. |
| Health & Family Welfare | TFR helps design maternal health, family planning, and childcare programs. |
| Social Development | A low TFR often reflects better education for women, urbanisation, and changing lifestyle choices. |
| Demographic Dividend | When fertility falls moderately, more people are of working age, giving a chance for higher economic growth. But if fertility drops too fast, it can lead to ageing and labour shortages. |
How is TFR Calculated?
- The reproductive age (15–49 years) is divided into 7 five-year groups:
- 15-19 years, 20-24 years, 25-29 years, 30-34 years, 35-39 years, 40-44 years, and 45-49 years.
- For each group, we find the Age-Specific Fertility Rate (ASFR).
- Each ASFR is multiplied by 5 (for 5 years) and divided by 1,000.
- Adding up the results for all 7 groups gives the Total Fertility Rate (TFR).
This method assumes that younger women today will behave like older women now when they reach that age, this is called the synthetic cohort assumption. This assumption is often unrealistic in a changing society like India.
What is Age-Specific Fertility Rate (ASFR)?
- The Age-Specific Fertility Rate (ASFR) represents the number of live births per 1,000 women in a specific age group during a given year.
- It shows which age groups contribute most to childbearing.
- Example: If the ASFR for the 20-24 age group is 120, it means 120 babies are born per 1,000 women aged 20-24 in that year.
- Relevance: ASFRs reveal shifts in fertility behaviour. For instance, a decline in fertility among younger women and a rise among older ones indicates delayed childbirth, not necessarily fewer births overall.
About the State of World Population 2025 Report
- Released by: UNFPA (United Nations Population Fund).
- Theme: Focuses on fertility, ageing, and population transitions across the globe.
- Key Finding for India:
- India’s TFR = 1.9, below the replacement level.
- Highlights the demographic transition from high fertility to potential population ageing.
- Raises questions on data accuracy and the impact of changing socio-economic trends, particularly in urban India.
Challenges and Way Forward
| Challenges | Way Forward |
| Synthetic Cohort Assumption: TFR assumes that younger women today will behave like older cohorts in future, unrealistic amid rapid social change. | Update fertility models using longitudinal data and cohort studies reflecting real-life fertility patterns. |
| Tempo Effect (Timing Bias): Delayed childbirth leads to artificially low TFR, even if total births remain the same. | Introduce tempo-adjusted TFR measures to capture postponed births accurately. |
| Point-in-Time Measurement: TFR represents fertility for one year, missing long-term trends. | Use multi-year averages or rolling fertility indicators for stability. |
| Underreporting of Births (especially below 15 and above 49): Early/late pregnancies (esp. in rural or conservative settings) may be hidden due to social stigma or survey bias. | Train enumerators, anonymise data collection, and improve survey sensitivity and coverage. |
| Urban-Rural Disparity: Urban women delay childbirth; rural women still have earlier fertility, making national averages misleading. | Calculate region-wise TFR for targeted policy interventions. |
| Cultural and Economic Transition: Women’s higher education and career goals shift fertility timing. | Encourage family-friendly work policies, childcare infrastructure, and flexible careers to support desired fertility. |
| Policy Misinterpretation: Panic over low TFR may prompt coercive or pro-natalist measures. | Adopt balanced, rights-based population policies focusing on health, education, and empowerment rather than numbers. |
Conclusion
India’s TFR of 1.9 demands cautious interpretation, it may mask timing effects, data gaps, and flawed assumptions. Rather than fearing low fertility, the focus should be on harnessing the demographic dividend through education, women’s employment, and ageing support. Population data must inform policy, not drive it blindly.

| Ensure IAS Prelims Question Q. With reference to the Total Fertility Rate (TFR), consider the following statements: 1. It represents the actual average number of children born per woman in her lifetime. 2. It is derived by adding the age-specific fertility rates (ASFR) for all reproductive age groups. 3. The replacement-level fertility rate is generally considered to be 2.1. Which of the statements given above is/are correct? a) 1 and 2 only b) 2 and 3 only c) 1 and 3 only d) 1, 2 and 3 Answer: b) 2 and 3 only Explanation: Statement 1 is incorrect: TFR does not represent the actual number of children born per woman; it is a hypothetical estimate based on current age-specific fertility rates, assuming they remain constant throughout a woman’s reproductive life. Statement 2 is correct: TFR is calculated by summing the age-specific fertility rates (ASFRs) across all reproductive age groups, adjusted for the five-year intervals. Statement 3 is correct: A TFR of 2.1 is generally considered the replacement-level fertility, which maintains population size in the absence of migration. |
