America Is Running Out of Places to Hang Out as Movie Theaters, Bars, Diners and Bowling Alleys Drop to All-Time Low

The figures document supply-side contraction of informal gathering venues rather than measured changes in social connection or isolation itself; readers should treat the cost-driver explanation as journalistic interpretation, not a tested causal claim, and pair these counts with survey-based loneliness or contact-frequency data before drawing conclusions about population-level effects.

Loneliness Strongly Linked to Poorer Mental Health and Wellbeing

The findings reinforce a well-established association but the summary provided offers no quantitative effect sizes, sample characteristics, or discussion of directionality, limiting its independent evidentiary value; readers should consult the full paper before citing magnitude of effect or drawing causal conclusions.
