Per capita is a Latin term that means "by head" and is used to express the average per person. It is often used in place of "per person" in statistical observances and is commonly used in economic and statistical analysis when comparing a certain economic metric to a population. The most common instances of per capita are gross domestic product (GDP) per capita and income per capita. Per capita expresses the average number for all of the citizens of a particular country or area, and it can be a misleading number because it includes everyone from infants to senior citizens and fails to account for statistical outliers. Therefore, the median income is often used to take into account any outliers. The term per capita is also used in the context of government demographic data, such as Gross Domestic Product (GDP) per capita, which refers to a countrys GDP divided by the countrys population. Under a will, the term per capita is commonly employed to determine what share of property each beneficiary gets when one of the beneficiaries dies before the testator (i.e., the deceased individual who created the will) leaving children of his or her own.
