  3. FERTILITY RELATED STATISTICS: • Birth rate: Birth rate=Number of live births during the *1000 year Estimated mid year population CBR(India)=22.2 (Kerala)=18.3

  4. General fertility rate (GFR): GFR= Number of live births in an area *1000 during the year Mid-year female population age (15-44) in the same area in the same year

  5. Age specific fertility rate (ASFR): ASFR=Number of live births in a particular age group *1000 Mid year female population of the same age group

  6. Total fertility rate(TFR): It represents the average number of children a woman would have if she were to pass through her reproductive years bearing children at the same rates as the women now in each group TFR = C * £ASFR 1000 TFR (India )=2.76 (kerala)=1.7

  7. Gross reproduction rate(GRR): GRR= C * £ ASFR for female live births 1000

  8. Net reproduction rate (NRR): The number of daughters a new born girl will bear during her life time assuming fixed ASFR and mortality rates.

  9. REASONS FOR HIGHER FERTILITY RATES IN INDIA: • Universality of marriage • Lower age at marriage • Poor level of living • Limited use of contraceptives • Traditional ways of life
