Others live with single or
cohabiting parents, in blended or polyamorous
families, with grandparents or in
multigenerational homes.
In what is perhaps the most comprehensive investigation of the implications of different kinds of
family structures for the well - being of teenagers, Thomas Deleire and Ariel Kalil studied more than 11,000 adolescents raised in ten different kinds of households, including, for example, households with married parents, biological
cohabiting parents, single mothers (divorced, always - single, and
cohabiting considered separately), divorced single mothers in multi-generational households, and always - single mothers in
multigenerational households.
