Birth rates in Delhi, Kerala, and T.N. declining at twice the rate of national average: report, Pg14

Key Highlights:

• Crude birth rates in Tamil Nadu, Delhi, and Kerala are declining at twice the national average.
  • India's overall crude birth rate dropped from 19.3 (per 1,000) in 2016 to 2021, a 1.12% annual decline.
  • Tamil Nadu’s decline rate: 2.35%, Delhi: 2.23%, Kerala: 2.05%.
  • States like Bihar, Uttar Pradesh, and Madhya Pradesh still have high birth and fertility rates, though slowly declining.

Detailed Insights: 1. Crude Birth Rate Trends (2016–2021):

• National average decline: 1.12% per year.
  • Rapid decline observed in southern states, especially:
    • Tamil Nadu (2.35%)
    • Delhi (2.23%)
    • Kerala (2.05%)
  • Uttarakhand was the only major state where birth rate increased during this period.

2. Fertility and Demographic Shifts:

• Southern states like Andhra Pradesh, Telangana, Karnataka, Kerala, and Tamil Nadu lead in demographic transition.
  • Northern and central states still show higher TFR (Total Fertility Rate) and GRR (Gross Reproduction Rate), with states like Bihar and Uttar Pradesh significantly above the national average.

3. Registered Births and Development:

• Despite declining birth rates, registered births are rising in 11 states and UTs due to:
  • Better reporting
  • Administrative efficiency
  • Health awareness

4. Policy Relevance:

• Data corresponds with Sample Registration System (SRS) 2021 and Civil Registration System 2021.
  • Indicates regional imbalance in population momentum, with southern states nearing or already at replacement-level fertility.

Scientific/Technical Concepts Involved:

• Crude Birth Rate (CBR): Number of live births per 1,000 people annually.
  • Total Fertility Rate (TFR): Average number of children a woman is expected to have during her reproductive life.
  • Gross Reproduction Rate (GRR): Average number of daughters born per woman.

Significance:

• Reflects demographic maturity in southern states; may soon face ageing population concerns.
  • High fertility in BIMARU states points to the demographic divide, influencing resource allocation, political representation, and labor force distribution.
  • Useful for population policy, urban planning, health infrastructure, and social welfare schemes.

Mains Mock Question:

Discuss the regional variations in birth and fertility rates in India. What are the implications of declining birth rates for southern states, and how should policymakers address emerging demographic challenges?
