Most of the time, people is the correct word to choose as a plural for person. Persons is archaic, and it is safe to avoid using it, except in legal writing, which has its own traditional language.

When a collective noun is called for (to refer, for instance, to the members of an entire nation) the appropriate word will always be 'people' ("the French people").

Is it persons, people or peoples? In most cases, people is the correct term to use as a plural for the word person. The word persons is considered archaic, so unless you’re doing some legal writing, it’s best to avoid it.

Persons and people are plural nouns for “person,” although “people” is the correct word for everyday English. For formal or legal writing, use “persons.”

Both persons and people are acceptable plural forms of person. They’re not necessarily always interchangeable, but there is some overlap. The plural form people is more common.
