The social fabric in the Mizo society has undergone tremendous change over the years. Before the British moved into the hills, for all practical purposes, the village and the clan formed units of Mizo society.

The Mizo code of ethics or Dharma moved round "Tlawmngaihna", an untranslatable term meaning on the part of everyone to be hospitable, kind, unselfish and helpful to others. Tlawmngaihna" to a Mizo stands for that compelling moral force which finds expression in self-sacrifice for the services of others. The old belief, Pathian is still in use to term God till today. The Mizos have been enchanted to their new-found faith of Christianity with so much dedication and submissioin that their entire social life and thought process have been altogether transformed and guided by the Christian Church organisations directly or indirectly and their sense of values has also undergone drastic change.

Mizos are a close-knit society with no class distinction and no discrimination on grounds of sex. Ninety percent of them are cultivators and the village exists like a big family. Birth of a child, marriage in the village and death of a person in the village or a community feast arranged by a member of the village are important occasions in which the whole village is involved.
