India, June 8 -- Andaman and Nicobar Islands have recorded India's lowest total fertility rate in NFHS-6, at 0.9.

The Union Territory's fertility rate is less than half the replacement rate of 2.1, indicating a significant population decline over time.

The share of children under five has fallen from 5.3% in NFHS-5 to 3.7% in NFHS-6, while the population aged 60 and above has increased.

Preschool attendance among children aged two to four has also dropped sharply, from 88.5% in NFHS-5 to 66.2% in NFHS-6.
