Expressing concern over declining population growth, RSS chief Mohan Bhagwat on Sunday said India's Total Fertility Rate (TFR), the average number of children a woman gives birth to in her lifetime, should be at least 3, well above the present one of 2.1.

Speaking at the 'Kathale Kul (clan) Sammelan' in Nagpur, Bhagwat also highlighted the vital role of families, and warned that according to population science, if a society's total fertility rate dips below 2.1, it could face extinction.
