India total fertility rate (TFR) dropped below the replacement level of 2.1 for the first time according to NFHS-5 (2019-21). What does a TFR below replacement level indicate about future population trends?

  • A An immediate and sharp decline in total population size within the same year
  • B Population will continue growing for decades due to population momentum before stabilising
  • C An acceleration of population growth driven by the existing large reproductive-age cohort
  • D A death rate that immediately surpasses the birth rate across all age groups

Correct answer: B. Population will continue growing for decades due to population momentum before stabilising

Explanation: Even when TFR drops below replacement level, population continues to grow for decades due to population momentum - the large proportion of young people who will still have children. India population is projected to peak around 2064.
