However, material circumstances on their own do not account fully for changes in co-residence.

Here housing and common work meant co-residence was to their mutual advantage.

Much of this co-residence appears to be driven by economic circumstance.

Such co-residence can be a valuable form of insurance, particularly for youths from poorer families.

Co-residence with children is an important element of the flow of support between family members.

My point here is simply that they do go some way to explaining why patterns of co-residence fluctuate over time.

Co-residence can also have negative effects on an emerging adult's adjustment and autonomy.

How much are a person's chances of survival, reproduction or co-residence with others affected by their command over economic resources?

Parental support may come in the form of co-residence, which has varied effects on an emerging adult's adjustment.

Co-residence and organization by kinship are both integral in the development of the concept of the family.

Thus the practice of co-residence of older people with their children is declining:

We should also not make the rather simplistic assumption that co-residence implies a strong bond between relatives.

We may, schematically, suggest the long-term co-residence of three separate layers of attitudes and beliefs.

The importance of co-residence and being primary provider of care for men's filial care involvement.

The term "family" today implies a kinship tie, while domestic groups are associated with function and co-residence simply implies shared dwelling space.

"Multigenerational co-residence will likely be a strategy used by many to deal with financial hardship caused by the loss of a job, house or retirement savings."

The same year, several Harvard and Radcliffe dormitories began swapping students experimentally and in 1972 full co-residence was instituted.

"Consequence of Parent-Adult Child Co-residence:

One last form of co-residence brought some of the closest relationships between grandparents and grandchildren, as well as some of the most sustained instances of tension.

These have been due to evolving patterns of co-residence related to the decline in marriage and increases in cohabitation and breakdown of both formal and informal sexual unions.

If we look at the reasons why kin shared homes with each other in the past, three themes emerge which help us further to understand why there have been fluctuations in co-residence.
