Morphology

baby + boom

The meaning is directly compositional: 'baby' (infants) combined with 'boom' (a sharp sustained increase) yields an increase in the number of babies/births. This noun+noun compounding pattern is regular in English and occurs cross-linguistically, so a B1 learner who knows both constituents would readily infer the MWE meaning.

Etymology

Baby boom comes from joining baby with boom, where boom suggests a sudden, loud event like an explosion to picture many births happening quickly. That's why baby boom means 'a sudden large rise in births', especially after World War II.
