1) Cradle of social virtues:

Joint family is like a nursery to teach social virtues. It helps to develop social virtues like co-operation, sympathy, sacrifice, affection, spirit of selfless service, obedience and broadminded.

2) Insurance against olds:

Joint Family Acts as insurance for the members of the family at the time of crisis. It provides social security to its members especially to the old, the infirm, the unemployed persons, the orphans, the widowed daughters and sisters as well as the physical and mentally handicapped among them. For all such persons the joint family acts as an insurance company.

3) Division of labour:

In a joint family each member is given work according to his or her capacity. The men, women and children all have to work. For example, in a peasant joint family all the members work actively according to their ability. The old persons and children of the family watch the crops in the field. During the harvest season, the women in some families help in harvesting. This there is no need of procuring labour from outside the family.

4) Socialism in Wealth:

According to Sir Henry Maine joint family is like a co-operative society with the father as the trustee. Every member in the joint family works conforming to the well established socialist formula; each works according to his or her ability and gets according to his or her needs.

5) Avoids fragmentation of land:

Joint family avoids the evils or fragmentation of land by holding the property in common. Joint family is almost like a joint-stock company.

6) An agency of social control:

Another advantage of joint family is that it acts as an agency of social control. In joint family there is a close supervision over the anti-social and unsocial activities of the young member.

7) Opportunity for leisure:

Joint family affords ample leisure to its members. Both the male and female members divide the household works and finish it in a short time spending the rest of the day in leisure. They never feel over burdened.

8) Money saving device:

Joint family is advantageous from the economic viewpoint. This system helps in securing economy in expenditure. Since things are consumed in a large quantity they can be obtained at cheap rate. A large family can be maintained within a small means if it lives jointly.
