India Population to Hit 1.6 Billion:India is set to become the world’s most populous country in 2025 with a projected population of 1.6 billion, surpassing China by a wide margin. However, a new UN report highlights deeper concerns beneath the numbers — including a steep decline in fertility rates and vast regional disparities. While urban areas see couples delaying or avoiding childbirth due to lifestyle and economic pressures, poorer states still struggle with high birth rates caused by limited access to healthcare and contraception. This blog explores the contrasting demographic realities shaping India’s future.
India Population to Hit 1.6 Billion
ndia is all set to achieve a demographic milestone in 2025, as per the recently released State of World Population Report by the United Nations Population Fund (UNFPA). The report projects India’s population to touch a staggering 1.6 billion this year — making it the most populous country in the world. China, which held that title for decades, is expected to fall significantly behind with a population of just 1.41 billion in the same period.
This surge represents a significant increase from India’s 2024 population count of 1.44 billion. Looking ahead, the report forecasts that India’s population will continue to grow until it peaks at around 1.7 billion people. However, this growth is expected to plateau and then decline approximately 40 years from now.
While the overall numbers point to rapid growth, a deeper dive into the report reveals emerging demographic concerns. One of the key issues flagged is the decline in the country’s Total Fertility Rate (TFR). The TFR, which refers to the average number of children a woman is expected to bear during her reproductive years, has dropped to 1.9. This is well below the replacement fertility level of 2.1 births per woman — the rate required to maintain a stable population size over generations.
This decline in fertility signals a demographic shift where Indian women, on average, are having fewer children than what is necessary for population replacement. While this may indicate progress in terms of access to education, family planning, and reproductive awareness, it also points toward growing economic and social pressures.
Importantly, the report notes that these trends are far from uniform across the country. Deep inequalities persist across states, social groups, and income levels. Fertility rates remain high in several northern and economically weaker states such as Bihar, Jharkhand, and Uttar Pradesh. In these states, unintended pregnancies and closely spaced births are still common. The causes are rooted in limited access to contraceptives, poor quality healthcare services, and persistent gender norms that restrict women’s reproductive autonomy.
On the flip side, states like Delhi, Kerala, and Tamil Nadu exhibit fertility rates well below the replacement level. Here, a different set of challenges emerges. Many couples, especially among the urban, educated middle-class, are postponing or even forgoing childbirth altogether. Contributing factors include the high cost of living, expensive education and healthcare, job pressures, and a lack of work-life balance. Women in particular are facing increasing difficulties in balancing careers with motherhood — leading to a significant shift in reproductive behavior.
The UNFPA’s report suggests that while India is growing, this growth comes with its own complexities. The overall decline in fertility should not mask the regional disparities and structural issues that continue to plague India’s reproductive health landscape. The path forward for India will require a two-pronged approach — managing the pressures of a large and growing population while simultaneously addressing the uneven development and persistent inequalities that shape the country’s demographic future.
