What does capita mean?
Capita is the plural of the Latin noun caput, which means head, and it enters modern English almost entirely through the statistical expression per capita, meaning per person or per head of population. Economists, demographers, and journalists use it constantly to convert raw totals into figures that can be fairly compared between countries of different sizes: national wealth becomes GDP per capita, alcohol sales become litres consumed per capita, and so on. The phrase carries no emotional connotation of its own, but the figures it produces are often politically charged, since per capita comparisons can flatter small wealthy nations or expose inequality within large ones. Although technically a foreign-language plural, capita behaves as an unchanging borrowed form in English and is never inflected further. Its survival is a small linguistic fossil: whenever a statistic is reported per capita, we are quite literally counting human beings by their heads, exactly as Roman record-keepers did two thousand years ago.
nounCapita is the plural of the Latin word caput, meaning "head"; in modern English it survives almost exclusively in statistical and economic phrases such as per capita, where it denotes individual persons counted as heads of population.

Every time you read 'income per capita', you're literally counting people by their heads — an accounting habit inherited straight from ancient Rome.

Etymology of capita
Capita comes directly from Latin, where it is the plural of caput, meaning head. The same root produced a remarkable family of English words via Old French, including capital, captain, cattle, and decapitate, all of which preserve the underlying idea of a head — whether as leadership, property counted by heads of livestock, or removal of one. In English, capita was borrowed as part of the legal and statistical phrase per capita, meaning 'by heads', and remains essentially confined to that construction today.

How capita is actually used
Capita is a Latin plural and is rarely used as a standalone English noun; it appears almost exclusively after 'per' in fixed statistical expressions. Because it is already plural, expressions like 'per capitum' are incorrect — 'per capita' means 'for each head'. In formal writing it is treated as an invariant borrowed form.
