Question

The following table gives the age and sex composition of population along with the number of live births in an year. Calculate total fertility rate.

Answer 1

TFR = 5 Σ Quinquennial ASFR’s ASFR

\(\frac {\textit{No.of Live births occuring in the year to women in the specified age group}}{\textit{Average population of women in the specified age group in the year}} \times 1000\)

ASFR_{(15 – 19)} =\(\frac{100}{1500}\) x 1000 = 66.66

TFR= 5 x 542.575 

= 2712.875 births per 1000 women.
