Often, it has been presumed that extended family groups sharing a single household enjoy specific advantages, such as a greater sense of security and belonging due to sharing a wider pool of members to serve as resources during a crisis, and more role models to help perpetuate desired behavior and cultural values. However, even in cultures in which adults are expected to leave home after marriage to begin their own nuclear-based households, the extended family often forms an important support network offering similar advantages. Particularly in working-class communities, grown children tend to establish their own households within the same general area as their parents, aunts, uncles, and grandparents. These extended family members tend to gather often for family events and to feel responsible for helping and supporting one another, both emotionally and financially.
