per capita

This term is primarily used in formal, technical, or academic contexts, particularly within economics, sociology, and statistics. It serves as a tool for normalization, allowing researchers to compare the wealth or resource distribution of populations of different sizes by reducing the data to a single individual's share.

Because it is a Latin loanphrase, it functions as a fixed unit. When used as an adjective, it typically precedes the noun it modifies, such as in "per capita GDP." When used as an adverb, it often appears at the end of a clause to specify the basis of a calculation.
