populationis

Populationis is a Latin noun form that appears as the genitive singular of populatio, a noun that can mean either "the population" or "the act of populating," depending on context. In Latin, the genitive populationis expresses possession or relation, as in phrases such as pars populationis ("part of the population") or quantitas populationis ("the quantity of the population"). The root populatio comes from populus, "the people," with the abstract suffix -atio.

Historically, populationis occurs in classical and medieval Latin writings when authors discuss populations, populations' sizes, or population-related concepts within larger statements. It is not a modern technical term and does not designate a separate field of study; rather, it functions as a grammatical form within phrases.

In modern scholarship, populationis may appear in Latin passages quoted in studies of demography or in Latin-language titles intended to evoke antiquity. Outside such contexts, it is treated as a Latin genitive noun form and not as a contemporary concept.
