Subcontinental Population Demographics: Below-Replacement Level Birth Rates Map Rapid Aging Cohorts Across Island Territories
In a critical demographic revelation requiring an immediate policy overhaul regarding sovereign population management, the Andaman and Nicobar Islands officially recorded India's absolute lowest Total Fertility Rate (TFR) during the National Family Health Survey-6 (NFHS-6). The island territory registered a startlingly low TFR of just 0.9, plunging well below the baseline metrics required to maintain generational population stability.
The 0.9 Below Replacement Collapse and Surging 60-Plus Cohorts
The quantitative health tracking matrix uncovers severe structural aging trajectories within the strategically vital union territory:
- Crashing Below Replacement Levels: For a sovereign population to strictly maintain long-term stability without immigration, the **baseline replacement-level fertility rate is mandated at 2.1**. Andaman and Nicobar’s TFR crashed dramatically from **1.4 in the previous NFHS-4 cycle to a mere 0.9 in the latest NFHS-6**.
- Collapsing Child Metrics: Highlighting the immediate lack of new births, the statistical share of **children below five years of age decreased sharply from 5.3% to a highly critical 3.7%**. Concurrently, **preschool attendance among children aged 2–4 years dropped heavily from 88.5% to 66.2%**.
- Rapid Cohort Aging: Demonstrating classic inverted-pyramid demographics driven by sub-replacement births, the percentage of the island's **population aged 60 years and above surged to 12.6%**, forcing localized administrations to urgently re-evaluate future labor availability and healthcare scaling.
