RELATIVE POVERTY LEVEL: The amount of income a person or family needs to purchase a relative amount of basic necessities of life. These basic necessities are identified relative to the current structure of society and the economy. For example, while a refrigerator would be a basic necessity for someone living in the our modern U.S. economy, it probably would not be consider a necessity for nomads of sub-Saharan Africa or aborigines of Australia.

CONCENTRATION RATIOS

A family of measures of the proportion of total output in an industry that is produced by a given number of the largest firms in the industry. The two most common concentration ratios are for the four largest firms and the eight largest firms. The four-firm concentration ratio is the proportion of total output produced by the four largest firms in the industry and the eight-firm concentration ratio is proportion of total output produced by the eight largest firms in the industry. Concentration ratios are commonly used to indicate the degree to which an industry is oligopolistic and the extent of market control of the largest firms in the industry. A related measure is the Herfindahl index.
