Poor people prefer to have large families. Explain the paradox

Dear Student
Poor people preferred to have large families because of various reasons:

• they need more hands to earn, so they have large families. mostly poor people live in rural areas and mostly do labour intensive kind of work , so they think that if they have large families more members of family can do work and they have more money.
• Although they do not have much access to education so they have less knowledge about having more children.
• Early marriage and gender differentiation is another reason of having more kids as they wants more male child to help them in earning money.
