Question

1. The sex ratio (Males: Females) in the world is 1.07 at birth, 1.06 for under age 15 years, 1.02 for 15-64 years, and 0.78 for 65 years and over. Explain this statement. [2]

Answer 1

Birth time ratio 1.07

under 15 ratio 1.06

15 to 64 ration 1.02

and above 64 ratio 0.76

ratio 1.07 means

if male 1007 female 1000

Male populations maximum as compared to female. But if your age increases then we can see ratio is decreases.

ratio 1.02

male 1002 female 1000

4 people difference between birth time ratio and this ratio

now above 64 ratio is 0.78

it means male 780 female 1000

very big difference. It clearly means that male death rate is maximum. 20% males death before age of 64, but females are long living..
