Sibling living, also known as sibling cohabitation or sibling household, refers to the arrangement where two or more siblings live together in a shared accommodation. This phenomenon has been on the rise in recent years, particularly among young adults and seniors. With the increasing costs of living, changing family structures, and evolving social norms, sibling living has become a viable option for many people.

The reasons for this shift are varied. For young adults, the rising costs of housing, education, and living expenses have made it challenging to afford independent living. Sibling living offers a cost-effective solution, allowing them to share expenses, household chores, and emotional support. For seniors, sibling living provides companionship, care, and support, which can be particularly important as they age.

The trend of sibling living is not new, but it has gained significant attention in recent years. According to a report by the Pew Research Center, in 2019, 31% of young adults aged 18-34 lived with a sibling, up from 22% in 1960. This trend is not limited to young adults; seniors are also opting for sibling living arrangements.
