Solo trajectories

Hypothesis

If Household of One plays out broadly

At scale, single-person households become the modal family unit in wealthy nations, reshaping housing size, portion sizing, and solo-oriented services as the default design target rather than the niche case.

If Demographic Winter Economy plays out broadly

At scale, shrinking, aging populations become the default market condition in wealthy and even some developing nations, forcing entire industries to redesign around fewer young consumers.
