Age Group (in years) 15 - 20 20 - 25 25 - 30 30 - 35 35 - 40 40 - 45 45 - 49 No. of Women 1276 3253 5628 7345 6901 4253 3957 No. of live births 218 361 693 1305 1031 634 390 Calculate from these information the general fertility rate of the town and the age specific fertility rates for the year

Given that, Age Group (in years) 15 - 20 20 - 25 25 - 30 30 - 35 35 - 40 40 - 45 45 - 49 No. of Women 1276 3253 5628 7345 6901 4253 3957 No. of live births 218 361 693 1305 1031 634 390 We know that, General fertility rate G F R = B t ∑ i = a 1 c 2 P t i × 1000 . The total number of women, at child bearing age in the district during the study period can be calculated from the given information as ∑ i = 15 49 P t i = 32613 and the total number of live births as B t = 4632 . ⇒ G F R = 4632 32613 × 1000 = 142 . 03 . ∴ General fertility rate G F R = 142 . 03 . We know that, Area Specific Fertility Rate A S F R x , x + n = B t ( x , x + n ) P t ( x , x + n ) × 1000 . The ASFR's are calculated from the given information and are presented in the following table: Age group AFSR 15 - 20 218 1276 × 1000 = 170 . 85 20 - 25 361 3253 × 1000 = 110 . 97 25 - 30 693 5628 × 1000 = 123 . 13 30 - 35 1305 7345 × 1000 = 177 . 67 35 - 40 1031 6901 × 1000 = 149 . 40 40 - 45 634 4253 × 1000 = 149 . 07 45 - 49 390 3957 × 1000 = 98 . 56 It is can be observed, with respect to ASFR's, that the women in the country falling in the age group of 30 - 35 ,years have given relatively more live births.
