The Total Fertility Rate (TFR) has dropped from 3.5 in 2000 to 1.9 in 2025, which is below the replacement level of 2.1.

States such as Kerala and West Bengal now have very low fertility levels, with TFRs of about 1.5 and 1.3.
Life expectancy is rising and creating a larger elderly population that needs more care.
