Recent data from the Sample Registration System (SRS) Statistical Report of 2021, released by the Registrar General of India reflects a fascinating and somewhat complex picture of how birth rates are changing across the nation. The numbers reveal a clear trend while the national average for the birth rate (the number of live births for every 1,000 people) is declining, some states are witnessing this decrease at a significantly faster pace.
Interestingly, the data highlights that Tamil Nadu, Delhi, and Kerala are leading this rapid decline, with their birth rates falling at twice the speed of the national average. This means that in these regions, fewer babies are being born relative to their population compared to the rest of the country. Joining this group of faster-than-average decline are also Maharashtra, Gujarat, Odisha, Himachal Pradesh, Haryana, and Jammu and Kashmir. Even Punjab is not far behind, with its birth rate decreasing at nearly the same pace as the national figure.
A Counter-Narrative and Rising Registered Births
However, when we look at a different set of data from the Civil Registration System (CRS) 2021, an intriguing narrative emerges. This dataset shows that some of the very states experiencing the slowest decline in birth rates are actually reporting an increasing number of registered births. This suggests that while the rate at which births occur might be slowing down in these regions, the absolute number of births being officially recorded is on the rise.
Specifically, the Vital Statistics Report based on the CRS 2021 indicates that about eleven states and union territories are seeing a growth in the number of registered births. These include Bihar, Rajasthan, Uttar Pradesh, Uttarakhand, West Bengal, Jammu and Kashmir, Ladakh, Lakshadweep, Arunachal Pradesh, Mizoram, and Nagaland. This could point to various factors, such as improved registration processes or perhaps a demographic momentum in these states.
Southern States Show Consistent Decline in Registered Births
Looking closer at the southern states, the CRS 2021 data reveals another distinct pattern. Andhra Pradesh, Tamil Nadu, Karnataka, and Kerala have consistently seen a decline in the number of registered births since at least 2012. While Andhra Pradesh did experience a slight increase in 2021, the overall trend for these states has been downward. Telangana presents a slightly different picture with a sharp increase in registered births after 2019, followed by a significant drop after 2020. This fluctuation now might even lead to further investigation to understand the underlying reasons.
National Average and Regional Variations in Decline Rate
The SRS 2021 data provides a clear national benchmark that the all-India crude birth rate in 2021 was 19.3. This rate has been falling by an average of 1.12% each year between 2016 and 2021. When we compare this to the frontrunners in decline, the numbers are very shocking. Tamil Nadu's birth rate has been dropping by 2.35% annually, Delhi's by 2.23% and Kerala's by 2.05% during the same period. This reinforces the observation that these regions are experiencing a more pronounced shift in their birth trends.
Interestingly, the report also notes that the Total Fertility Rate (TFR), which represents the average number of children a woman is expected to have in her lifetime remained constant at 2.0 across India in 2021. This suggests that while the birth rate might be declining, the average family size at a national level has been stabilized for the time being.
The states with the slowest rates of decline in birth rate include Rajasthan (0.48%), Bihar (0.86%), Chhattisgarh (0.98%), Jharkhand (0.98%), Assam (1.05%), Madhya Pradesh (1.05%), West Bengal (1.08%), and Uttar Pradesh (1.09%). Notably, Uttarakhand was the only state that actually saw an increase in its birth rate during this period by making it an outlier in the national trend.
Further analysis of the SRS 2021 data reveals that 13 large states and union territories are experiencing a faster rate of decline in birth rate than the national average. Unsurprisingly, all the southern states – Andhra Pradesh, Telangana, Karnataka, Kerala, and Tamil Nadu are a part of this group. This underscores a significant demographic shift occurring in the southern part of the country.
Understanding the Data: SRS and GRR
To understand these trends better, it's important to remember that the SRS is a crucial demographic survey providing annual estimates on vital indicators like birth and death rates. Covering a vast sample across India, it offers valuable insights into population dynamics, often complementing the information gathered through the decennial Census (which has not been conducted for 2021).
Another key metric highlighted in the SRS 2021 is the Gross Reproduction Rate (GRR). For India as a whole, the GRR stands at 1.0, meaning that, on an average each woman is having one daughter who survives to have children of her own. However, there are significant regional variations. Bihar, Rajasthan, Madhya Pradesh, and Uttar Pradesh have GRRs considerably higher than the national average which is indicating a higher rate of potential future population growth in these states.
West Bengal's Unique Demographic Position
In contrast, West Bengal presents a unique scenario. Despite reporting an increase in registered births and one of the slowest declines in birth rates, its TFR is the lowest among the larger states and union territories at 1.4. Similarly, its GRR is also low at 0.7. This suggests that while the number of births might be stable or slightly increasing, the average number of daughters being born per woman is quite low, potentially impacting long-term population replacement.
The latest data on birth rates in India reveals a complex interplay of trends. While many states, particularly in the south, are experiencing a rapid decline in birth rates but others are seeing an increase in the absolute number of registered births despite a slower rate of decline. These regional variations emphasize the diverse demographic transitions occurring across the country and highlight the need for nuanced policy approaches that consider these distinct patterns. Understanding these shifts is crucial for effective family planning and resources allocation as India is experiencing a birth decline in some states.
