Assam’s Fertility Rate Falls Below Replacement Level: Demographic and Cultural Implications
Source: The Assam Tribune
Why in News ?
Key Points :
- NFHS-6 Findings — Assam’s Total Fertility Rate (TFR) has declined to 1.6, below both the replacement level fertility (2.1) and the national average.
- Twenty-Year Decline — Assam’s TFR fell from 2.6 in NFHS-3 (2005-06) to 1.6 in NFHS-6, representing a decline of approximately 38% over two decades.
- Rural-Urban Gap — Under NFHS-6, rural Assam recorded a TFR of 1.7, while urban Assam reached 1.2, indicating a much sharper fertility decline in urban areas.
- NFHS Trendline
- NFHS-3 (2005-06): 2.6
- NFHS-4 (2015-16): 2.2
- NFHS-5 (2019-21): 1.9
- NFHS-6 (latest): 1.6
The data indicates a sustained downward demographic transition.
- Replacement Fertility Level — A TFR of 2.1 children per woman is generally considered necessary to maintain a stable population size without migration.
- Assamese-speaking Population Concern —The fertility rate among the broader Assamese-speaking cultural population is expected to be around 1.2, significantly below replacement level.
- Community-wise Variation — Assam’s Muslim population, constituting approximately 34% of the state’s population, is estimated to have a TFR near 2.0, though it is also declining.
- Role of Public Health — Declining fertility is attributed to:
- Expansion of ASHA workers’ outreach
- Increased female education
- Improved access to contraception
- Better maternal and child health services
- Changing family-size preferences
- Demographic Transition — Lower fertility typically leads to:
- Ageing population
- Shrinking workforce
- Rising dependency ratio
- Increased healthcare and elderly-care burdens
Global Comparison — Assam’s low fertility trajectory resembles with countries such as:
- Japan
- South Korea
South Korea’s TFR has reportedly fallen to around 0.72(2023), despite extensive government incentives.
