Per capita means Per person; generally used in expressions of water use, gallons Per capita per day (gpcd).

Per capita is a Latin prepositional phrase.

"Per" is a preposition, taking the accusative case, meaning "by, or by means of". "Capita" is the accusative plural form of the Latin noun "caput", meaning "head". Taken together, "per capita" therefore means "by heads" or "for each head", or more accurately, per person or on an individual basis.
