Driven by a dramatic regional contrast—where Bihar records the nation's highest fertility rate at 2.9, and Delhi plunges to the lowest at a mere 1.2—India’s national Total Fertility Rate (TFR) has officially dropped below the replacement threshold for the first time.
This landmark shift was documented in the Sample Registration System (SRS) Statistical Report 2024, released by the Office of the Registrar General and Census Commissioner under the Union Ministry of Home Affairs.
What is TFR?
The Total Fertility Rate (TFR) represents a critical demographic metric: it calculates the average number of children a woman is expected to give birth to over her lifetime.
In 1950, India was home to 360 million people, and the average woman gave birth to six children. Today, the population has expanded to 1.45 billion. After surpassing China in 2023 to become the globe's most populous nation, India's population has continued its upward trajectory.
The country's overall TFR has now dipped below the standard replacement benchmark of 2.1. Demographers note that if fertility rates persist below this line over an extended duration, the nation's population growth will inevitably begin to decelerate.
According to research from the Institute for Health Metrics and Evaluation (IHME) at the University of Washington, India’s population is projected to peak in 21 years. Following this maximum threshold, the country is expected to experience a sharp demographic decline.
Bihar is followed by Uttar Pradesh with a fertility rate of 2.6, Madhya Pradesh at 2.4, and Rajasthan at 2.3. Currently, these are the only major states that still maintain fertility levels above the 2.1 replacement mark.
Tamil Nadu, Kerala, and West Bengal all reported a low TFR of 1.3. Meanwhile, Andhra Pradesh, Jammu and Kashmir, Maharashtra, and Punjab registered a rate of 1.4, followed by Himachal Pradesh, Karnataka, and Telangana at 1.5.
This downward trend caught the attention of tech billionaire Elon Musk, who commented on the shifting demographics via social media. Writing on X, Musk observed that India's overall birth rate has dropped below replacement levels, noting that this shift occurred many years earlier among the country's most educated demographics.
Factors behind the decline
*The Economist highlights that changing parental aspirations are a key driver, with many lower-income families choosing to have only one child to afford better education and private tutoring.
*Driven by urbanisation, nearly 70% of Indians now live in nuclear families. The erosion of the joint-family system eliminates shared childcare, increasing pressure on parents and leading them to choose smaller families.
*Beyond economics and changing household structures, shifting cultural attitudes are fundamentally altering reproductive choices.
*Smaller families have increasingly become the cultural ideal, a transformation heavily accelerated by widespread access to information and modern technology.
