Research: Affordable housing is a significant problem in many cities, including Barcelona and here in Boston (as identified by 100 Resilient Cities). One solution to this lack of housing is living in a multi-generational home. Many cultures already embrace this ideal and reap the benefits that come with it. Families are closer when there are different generations living together, and it benefits each generation in the household differently. For example, a family with grandparents, parents, and grown children might put this method of solution to use. Each member of the family soon gains a sense of purpose and feels needed. For elders, this is especially great. Elder citizens that live in these multi-generational homes, say that they feel younger and healthier when being put to use (i.e. babysitting, contributing to the household chores, etc.) This is also a great solution that appeals to many post-graduate age adults. Moving back in with mom and dad doesn't sound like the greatest solution, but for many it is. It allows for the individual to save up money for their own home, they spend more time with their parents and other family members, and often times individuals are more than satisfied living this way. In cities where affordable housing is sparse, multi-generational living is becoming more and more popular among all cultures.
