This is a list of countries or dependencies by income inequality metrics

 (CIA). Note that because the underlying household surveys differ in method and in the type of data collected, the distribution data are not strictly comparable across countries. The Gini coefficient is a number between 0 and 1, where 0 corresponds with perfect equality (where everyone has the same income) and 1 corresponds with perfect inequality (where one person has all the incomeand everyone else has zero income). All Gini coefficients are before taxes which will tend to decrease the wealth of the upper income groups and decrease the value of the Gini coefficient. Income distribution can vary greatly from wealth distribution in a country. See: List of countries by distribution of wealth. Where information is unavailable it is marked N/A.
Income inequality can only be calculated accurately if all income data is included in the calculations. Many financial transactions take place off the books in the so-called "shadow economy"; also called the cash economy, off-the-books economy, informal sector, black markets, System D., etc.. For 2002/2003 the estimated size of the "shadow", unrecorded, unregulated and untaxed, economies (in percent of official GDP) is an average of 43.2% in Africa, 43.4% in South and Central America, 40.1% in East and Central European countries, Russia and former Soviet Union countries, 30.8% in Asia (excluding Russia and Japan), and 16.3% in OECD countries (which varies from 28.2% in Greece to a low of about 8.4% in the United States, 9.4% in Switzerland, and 10.8% in Japan).
