Hidden Micro-Communities

Large shares of people belong to tight-knit, offline–online affinity groups that look like hobbies from the outside but function as social infrastructure (rituals, norms, marriage markets, mutual aid), and remain largely invisible to outsiders’ perception and to official metrics. — This reframes the ‘loneliness/atomization’ debate, cautions against policy built on visible institutions alone, and suggests new measurement and governance approaches for social capital that account for niche, voluntary communities across domains.
