I think we’re the only middle aged couple with no kids on this street and adjacent ones. Every couple I’ve seen even remotely near our age when we walk our dog either has children or a pram.

Did try to make friends with some new neighbours a while back that were roughly our age. Very friendly first chat, they were both enthusiastic about greeting us - they approached us first.

The first thing they asked was whether we had children, when we said no they were visibly disappointed and seemed to lack interest in furthering the conversation.
