Yeah, and it forces kids to need to do "activities" to even see other kids. Makes proper development for kids much more expensive than the essentially free "existing alongside other kids" that happens in the multi-generational home.

In many cities in india, there is somewhat of a revival of this setup. What happened was that people weren't able to get homes with their aspirational square footage in the location they want. So what they end up doing these days is taking their family, the wifes family and the kids and buying 2-3 apartments in the same building. It's the closest you get to a multi-gen home. Will be interesting to see if this trend affects TFR.

Note that the recent +10% increase in TFR in rich indian states (you would expect a decline) is mostly due to better IVF availability/affordability, not due to any of the reasons I mentioned.

Yeah, this exposure also blunts some of the fear&uncertainty that puts people off of having kids.
