Families are formed by the community’s rules: the Committee of Elders matches spouses, then couples may apply for children, and babies born to Birthmothers are named and assigned to family units.
No one chooses a romantic partner or has biological children within a family. The Matching of Spouses can take years, and after a couple is matched, they are monitored for three years before they are allowed to apply for a child. "Birthmothers" give birth as their assigned job, but they do not raise or even see their "newchildren." This process separates reproduction from parenting and prevents biological family bonds from forming.
Children enter families at the Ceremony of One, when the Chief Elder gives each newchild a name and assigns the child to approved parents. Each family unit is allowed only one male child and one female child. Jonas’s family has Jonas and Lily, and when Lily jokes that they might keep Gabriel, her mother reminds her of this rule. Gabriel is allowed to stay temporarily with Jonas’s family only because Jonas’s father asks for extra nurturing time for him, and the family must promise not to become attached.
These family units are also temporary. Once children grow up, parents are moved to the House of Childless Adults, then later to the House of the Old. Jonas learns from The Giver’s memory of grandparents and love that his own community lacks lasting family relationships across generations. When Jonas asks his parents, “Do you love me?” his father answers, “Jonas. You, of all people. Precision of language, please!” Their response shows that while the family structure in the community can provide care and a sense of security, it isn't based on deep emotional bonds.
Family in The Giver is organized to serve stability and "Sameness." Jonas’s longing for Gabriel, grandparents, and love pushes against a system that treats family as something to be arranged and managed rather than something to be developed organically.
