Historically, the Joint Family—where multiple generations live under one roof sharing a common kitchen and finances—was the norm.
There is a saying in Hindi: "Ghar wahi, jahan khana pakta hai, aur thoda sa drama hota hai." (Home is where food is cooked, and there is a little bit of drama). jahan khana pakta hai
The traditional 20-person joint family is pivoting into the "mutual benefit nuclear" model. Today, young couples live in a separate flat—but in the same building as their parents. It is called the "two-key" system. jahan khana pakta hai
