The typology of families is not limited to a list of configurations. Each family structure produces relational dynamics, legal issues, and distinct modes of socialization. Here, we offer a technical reading of these configurations, emphasizing the dimensions that mainstream approaches overlook: the spatiality of the home, the impact of digital technology, and the concrete implications for parenting.
Multi-local families and shared custody: the ignored spatial dimension
Classic typologies (nuclear, blended, single-parent) describe the composition of the household, not its geography. This is a major gap. Since the mid-2010s, shared custody has been gaining ground as a mode of family organization, redefining routines, affiliations, and reference points for the child.

A child in shared custody does not live in a single-parent family nor in a nuclear family. They grow up in a multi-local family, with two distinct homes, two sets of rules, and sometimes two different sibling groups. This configuration requires ongoing parental coordination, often facilitated by dedicated apps or messaging groups.
The spatial dimension also affects blended families, where half-siblings and step-siblings reside in different homes. It also concerns transnational families, which maintain connections through video conferencing across multiple countries. To properly identify the different types of families, we recommend systematically integrating this geographical variable into any analysis.

Nuclear family and extended family: two logics of socialization
The nuclear family (two parents and their biological children under one roof) remains the most common configuration in France. Its distinguishing feature is not its frequency but its logic of socialization: the child builds their reference points within a limited circle, with parental roles concentrated on two adults.
The extended family operates on an inverse principle. Grandparents, uncles, aunts, and cousins actively participate in education and the transmission of norms. Parental functions are distributed among several members, altering the hierarchy of authorities perceived by the child.
Operational distinction criteria
- The number of adults exercising daily educational authority over the child (two in the nuclear family, variable in the extended family)
- Effective cohabitation: the extended family often involves shared housing or immediate geographical proximity
- The role of intergenerational ties in the transmission of social and cultural norms
We observe that the boundary between these two models blurs in practice. A nuclear family geographically close to its ancestors can function like an extended family without carrying that name.
Single-parent family and blended family: distinct parenting challenges
The single-parent family concentrates all parental functions on one adult. This burden is not only material. Primary socialization relies on a single reference, which alters the educational dynamic: absence of parental counter-power on a daily basis, unilateral decisions, solitary conflict management.
The blended family poses a different structural problem. It introduces a stepparent whose legal status remains unclear under French law. The question of the social parent, that is, the adult who plays a parental role without biological ties or adoption, remains a blind spot in the legal framework.
The status of the social parent in blended families
The stepparent has, in principle, no parental authority over their partner’s child. They cannot sign a school outing permission slip, make an urgent medical decision, or represent the child administratively. This legal void creates a gap between daily reality and the law.
Recent developments have attempted to address this, notably through partial delegations of parental authority. Their implementation remains cumbersome and not easily accessible to families without legal support.
Same-sex family: legal recognition and structural specificities
The same-sex family refers to any configuration where at least one of the parents identifies as homosexual. It can take the form of a nuclear family (same-sex couple with a child), a blended family, or co-parenting among several adults.
Its specificity does not lie in the quality of the parenting exercised, on which the scientific literature finds no significant difference compared to other configurations. It is found in the modalities of access to parenthood: adoption, assisted reproductive technology, surrogacy depending on jurisdictions, co-parenting with a third-party donor.
These pathways to parenthood often involve multiple reference adults from the outset of the parental project, which brings some same-sex families closer to the multi-local model described above.
Digital family culture: a cross-cutting parameter for all structures
Regardless of the type of family, digital technology restructures family life. Coordination between separated parents occurs through WhatsApp groups or co-parenting apps. School monitoring takes place through digital workspaces. Transnational families maintain their connections through video conferencing.
This digital family culture influences the distribution of parental tasks, the way conflicts are resolved, and the primary socialization of the child. Negotiating screen time becomes a structuring educational issue that crosses all family configurations.
- Managing co-parenting remotely via dedicated digital tools
- Maintaining intergenerational ties in geographically dispersed families
- Education about information and negotiating screen time as new markers of parenting
Classifying families solely by their composition remains reductive. The spatiality of the home, the legal status of the adults present, and the digital tools of parenting constitute three discriminating variables that any serious analysis of family structures would benefit from integrating.
