‘People’ vs. ‘Persons’

1. Common Modern Usage

Generally ‘person’ is used for the singular. ‘People’ is used for the plural.

1 person
100 people

2. ‘Persons’

The common modern usage of ‘person’ and ‘people’ is quite simple. However, the technical usage is not so clear because the language has changed. Consequently ‘persons’ is still used in certain areas.

Historical meaning still used in technical circumstances

In the past:
‘people’ = the population as a whole (e.g. ‘the people’, ‘The American people’)
‘person’ = an individual (‘I am a person’)
Therefore, when discussing two or more individuals ‘persons’ was used.

This usage continues in technical, legal and formal language. The reason is to highlight that even if there is more than one person, each person is an individual with rights, opinions and/or responsibilities.
