3. pre-reproductive individuals are more than the reproductive individuals
4. pre-reproductive individuals are less than reproductive individuals

Q. How does an age pyramid for human population at given point of time helps the policy makers in planning for future?

Q. In growing population of a country

1. reproductive and pre-reproductive individuals are equal in number
2. reproductive individuals are less than the post-reproductive individuals
3. pre-reproductive individuals are more than the reproductive individuals
4. pre-reproductive individuals are less than reproductive individuals

Q. Certain characteristic demographic features of developing countries are

1. Maximum age distribution is in Pre-reproductive phase
2. Maximum age distribution is in Post-reproductive phase
3. Pre- reproductive, Reproductive and Post-reproductive phase are even
4. Uneven population distirbution

Q.
