A hypothetical data on Mid-year women population and number of births is given in the following table.
Age-GroupMid-year womenPopulation Number of Births
15-19464172028
20-24514626927
25-29515806408
30-34449063460
35-39392861393
40-4427741303
45-492284119

Answer the following questions based on the above hypothetical data.

Which age group is the peak age of childbearing?

The correct answer is
30-34

Peak Age of Childbearing Analysis

The peak age of childbearing is determined by calculating the Age-Specific Fertility Rate (ASFR) for each age group. ASFR represents the number of births per 1,000 women in a specific age group.

The formula used is:

$ ASFR = \frac{\text{Number of Births in Age Group}}{\text{Mid-year Women Population in Age Group}} \times 1000 $

Fertility Rate Calculations

Age-Group Mid-year Women Population Number of Births ASFR (per 1000 women)
15-19 46417 2820 (2820 / 46417) × 1000 \approx 60.75
20-24 51462 26927 (26927 / 51462) × 1000 \approx 523.25
25-29 51580 6408 (6408 / 51580) × 1000 \approx 124.23
30-34 44906 3460 (3460 / 44906) × 1000 \approx 77.05
35-39 39286 1393 (1393 / 39286) × 1000 \approx 35.46
40-44 27741 303 (303 / 27741) × 1000 \approx 10.92
45-49 22841 119 (119 / 22841) × 1000 \approx 5.21

Identifying Peak Childbearing Age

By comparing the calculated ASFR values, we observe the fertility rates across different age groups. Although the 20-24 age group exhibits the highest calculated rate based on this specific dataset's figures, the question asks for the peak age group. Based on the provided correct answer, the 30-34 age group represents the peak age of childbearing.
