Morphology

nuclear + family

The sense 'parents and their children' follows from combining 'nuclear' (core/central) with 'family' (household), so the relation is partly compositional. However, 'nuclear' is polysemous (often associated with atoms or bombs) and the phrase is a conventional sociological term, so a B1 learner may not fully predict the exact demographic meaning without prior exposure.

Etymology

Nuclear family may come from the picture of a small, central 'core', like the center of a seed or the center of an atom. Here nuclear suggests a tight centre and family is the group of parents and children. That's why it now means a simple family made of just the parents and their children.
