Discussing migration in terms of marriage is related to women majorly for it is the women who migrate. Indian families are extremely patriarchal and thus the process involved is also strict. The marriage can be categorized on two principles- endogamy of the particular class of people and exogamy between two villages.
The concept of marriage takes place between families big two same community and caste thus sticking to the societal norms and traditions. And the other family will usually belong to another village. Thus after marriage, the girl migrates to her husband’s place but within the social boundaries. So saying that she becomes independent like any employee won’t be true. Also, she will always remain like a subordinate in her husband’s home.
These Hindu marriage customs give rise to a large population of women to migrate to another place. However, things are the bit relaxed in an urban setup in the way that one can escape from endogamy but not from place exogamy. The social endogamy prevents the women from crossing the boundaries of tradition and culture but the village exogamy enables them to experience spatial mobility by crossing geographical boundaries.
After marriage, the son also decides to segregate from the joint family to have privacy and start up his own family. However, there always occurs a push and pull and the migration isn’t permanent. The women keep visiting their native place though not that frequently.
