In India, human population is heavily weighted towards the younger age groups as a result of

1. short life span of many individuals and low birth rate
2. long life span of many individuals and low birth rate
3. low birth rate of many individuals and high birth rate
4. short life span of many individuals and high birth rate

Correct answer: short life span of many individuals and high birth rate

Solution

A population becomes youth-heavy when births are high, adding many children to the base of the age structure. If life span is short, fewer people remain in older age groups, so the younger groups make up a larger share.
