The term identifies arrangements where individuals, typically in their 50s, establish familial-like bonds that encompass mutual support and shared experiences, often including shared living arrangements and financial collaboration, without the traditional expectations of romantic partnership or marriage. These connections can provide companionship and practical assistance, differing from conventional family structures. For example, two single individuals in their mid-50s might purchase a home together, sharing expenses and providing emotional support for each other, thereby creating a supportive environment akin to a familial unit.
This type of relationship structure offers benefits such as reduced living expenses, shared responsibilities, and increased social interaction, particularly relevant during life stages when social circles may diminish. Historically, similar arrangements have existed within extended family networks or close-knit communities, but the intentional creation of such bonds outside of traditional family norms is a more recent phenomenon, driven by factors such as changing demographics, evolving social attitudes toward relationships, and increased financial pressures.
