In modern Western cultures dominated by immediate family constructs, the term has come to be used generically to refer to grandparents, uncles, aunts, and cousins, whether they live together within the same household or not.
The stem family is sometimes associated with inegalitarian inheritance practices, as in Japan and Korea, but the term has also been used in some contexts to describe a family type where parents live with a married child and his or her spouse and children, but the transfer of land and moveable property is more or less egalitarian, as in the case of traditional Romania,[3] northeastern Thailand[4] or Mesoamerican indigenous peoples.
[5] In these cases, the child who cares for the parents usually receives the house in addition to his or her own share of land and moveable property.
[citation needed] 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.
[11] In Britain and the United States, during the Industrial Revolution (approximately 1750 to 1900), more people lived in extended families than at any time before or since.
The patriarch's wife generally exerts control over the household, minor religious practices and often wields considerable influence in domestic matters.
[16] According to results of a study by Pew Research Center in 2010, approximately 50 million (nearly one in six) Americans, including rising numbers of seniors, live in households with at least two adult generations, and often three.
The main reasons cited for this shift are an increase in unemployment and slumped housing prices and arrival of new immigrants from Asian and South American countries.
The Supporting Grandparents Raising Grandchildren Act was signed into law on July 7, 2018 after unanimously passing the U.S. House and Senate.
Out of this came The Supporting Grandparents Raising Grandchildren Advisory Council which will identify, promote, coordinate, and disseminate to the public information, resources, and the best practices available to help grandparents and other older relatives both meet the needs of the children in their care and maintain their own physical and mental health and emotional well-being.
[23] Some scholars have used the term "grand-family" to describe the close relationship between grandparents, children, and grandchildren in Mexican society.
[24] The relative economic deprivation of racial and ethnic minorities leads to higher levels of extended family involvement; primarily because blacks and Latinos have less money and education than whites, they are more likely to give and receive help from kin.
[27] Being able to rely on not only two parents but grandparents, aunts, uncles, brothers, and sisters helps to create a support system which in turn brings families closer together.
[28] While high unemployment and housing foreclosures of the recession have played a key role in the trend, Pew Research Center exec VP and co-author of its multigenerational household study Paul Taylor said it has been growing over several decades, fueled by demographic and cultural shifts such as the rising number of immigrants and the rising average age of young-adult marriages.
