>This genuinely threw me because in my experience the suburbs are the antithesis of this, just lots of people occupying neighboring space and rarely talking to each other.

I've lived in both settings, and my own experience has been a mix. In the (walkable) suburbs I've lived in, I've connected with my immediate neighbors, strength of connection rapidly dissipates with distance. We are friendly, occasionally have a BBQ or meal together, and lots of random chats while going for a walk or doing yard work.

When I've lived in cities, it's been a much larger and more active community where the connection is less about proximity of our homes, and more about being in the same place at the same time since our daily errands and living were generally on foot. For those and the simple reason of small homes, we were more likely to meet somewhere or do an activity. I was also FAR more likely to run into someone I knew in my city than I was in my suburbs.
