The Gini coefficient (also known as the Gini index or Gini ratio) is a measure of statistical dispersion developed by the Italian statistician and sociologist Corrado Gini and published in his 1912 paper "Variability and Mutability" (Italian: Variabilità e mutabilità).

The Gini coefficient measures the inequality among values of a frequency distribution (for example levels of income). A Gini coefficient of zero expresses perfect equality where all values are the same (for example, where everyone has an exactly equal income). A Gini coefficient of one (100 on the percentile scale) expresses maximal inequality among values (for example where only one person has all the income).

It has found application in the study of inequalities in disciplines as diverse as sociology, economics, health science, ecology, chemistry, engineering and agriculture. It is commonly used as a measure of inequality of income or wealth. Worldwide, Gini coefficients for income range from approximately 0.23 (Sweden) to 0.70 (Namibia) although not every country has been assessed.

Chapter 14 is an American alternative metalcore rock band from Carlsbad, California currently consisting of vocalist Chad Ackerman (Destroy the Runner, As I Lay Dying, Austrian Death Machine), guitarist Tanner Sparks (Destroy the Runner), bassist Edwin Peraza, and Jonathan Knauer on drums.

Founded in 2003 by Ackerman and Sparks the band also consisted of drummer Mike Catalano (Chiodos, Destroy the Runner), guitarist Noah Slifka (In Fear and Faith) and bassist Eddie Hudson (Paper Mache). The band was unable to put together a full-length album but did complete two full U.S. tours and several demos without a label or financial backing.

After four years trying to land a record deal the band split up in 2007 when Ackerman and Sparks were offered the roles of vocalist and bassist for Destroy the Runner’s departing Kyle Setter and Jeremiah Crespo respectively. Noah Slifka went on to join In Fear and Faith the same year while Mike Catalano would join back up with Ackerman and Sparks in Destroy the Runner in 2008. Eddie Hudson moved on to play bass for the band Paper Mache. Chad explains what happened with Destroy The Runner and what Chapter 14 has for future plans
