Children in gated communities bond together far better..I have experienced life in two gated communities in Chennai and in Coimbatore. While the first experience was in a big metro, the second one was in a mini=metro. The first gated community, where there are flats of only one size and only up to four floors ( ground floor and only three above) at Velacheri, a posh locality of Chennai, is more than two decades old but remains rock solid because of the quality of construction. The complex has around 98% owners and only a few tenants. The children belong to upper-middle-class families of professionals like dentists, doctors, chartered accountants, senior-level executives, and college teachers. Dual incomes are very common. Almost ditto is the situation in Coimbatore. The children share common interests. They are very much IT savvy and enjoy fairly more than average comforts. They may study in different CBSE schools, but they have common study sessions. The parents also encourage a lot of bonding and there is no difference between children on the basis of caste or community or religion or region.
This is perhaps the same in other gated communities across India. Members who have experiences of bonding between children may share their experiences.
