Low Fertility Rate Raises Population Concerns in Tamil Nadu
- Context: Tamil Nadu’s Total Fertility Rate (TFR) has declined to 1.3 (from 1.4 in 2025), well below the replacement level of 2.1, while India’s TFR is 1.9. TFR is the average number of children a woman is expected to have during her reproductive years (15–49 years). The decline reflects improved education, healthcare, urbanisation, and family planning. However, sustained low fertility may lead to population ageing, labour shortages, and higher old-age dependency.
Drivers of the Decline in Tamil Nadu
- The drop to 1.3 is not an anomaly but the result of sustained socio-economic advancements:
- High Female Literacy & Education: Increased enrolment in higher education delays the average age of marriage and first pregnancy.
- Robust Healthcare Infrastructure: Low Infant Mortality Rate (IMR) and Maternal Mortality Rate (MMR) eliminate the “insurance effect” (having more children to ensure some survive).
- Urbanisation & Cost of Living: Over 50% of Tamil Nadu is urbanised. High costs of housing, modern education, and childcare disincentivise large families.
- Successful Family Planning: Early and aggressive implementation of the “two-child norm” since the 1970s, transitioning smoothly into a voluntary “one-child” preference among many urban couples.
Social & Healthcare Challenges
- Old-Age Dependency: A rising old-age dependency ratio puts immense pressure on familial care structures and state social security.
- Feminisation of Ageing: Women tend to outlive men, leading to a high population of dependent, elderly widows requiring targeted social protection.
- Geriatric Healthcare Shift: The state’s medical infrastructure must pivot from maternal/child health to chronic, age-related non-communicable diseases (NCDs) and palliative care.
