The two world wars were very big factors in keeping inequality low at the time. The rich were being heavily taxed by governments to finance the two conflicts, lowering inequality. After the wars, more socialist movements and trade unions emerged demanding better pay and working conditions, giving workers more power and lowering inequality.
World Inequality Report is a report by the World Inequality Lab at the Paris School of Economics that provides estimates of global income and wealth inequality based on the most recent findings compiled by the World Inequality Database (WID). WID, also referred to as WID.world, is an open source database, that is part of an international ...
Bennett's inequality, an upper bound on the probability that the sum of independent random variables deviates from its expected value by more than any specified amount Bhatia–Davis inequality , an upper bound on the variance of any bounded probability distribution
International inequality refers to inequality between countries, as compared to global inequality, which is inequality between people across countries. International inequality research has primarily been concentrated on the rise of international income inequality, but other aspects include educational and health inequality , [ 1 ] as well as ...
Buildings in Rio de Janeiro, demonstrating economic inequality. Effects of income inequality, researchers have found, include higher rates of health and social problems, and lower rates of social goods, [1] a lower population-wide satisfaction and happiness [2] [3] and even a lower level of economic growth when human capital is neglected for high-end consumption.

On the other hand, those in the middle class of the developed world (those in the 75th to 90th percentile in 1988, such as the American middle class) experienced little real income gains. The richest 1% contains 60 million persons globally, including 30 million Americans (i.e., the top 12% of Americans by income were in the global top 1% in ...
There are three inequalities between means to prove. There are various methods to prove the inequalities, including mathematical induction, the Cauchy–Schwarz inequality, Lagrange multipliers, and Jensen's inequality. For several proofs that GM ≤ AM, see Inequality of arithmetic and geometric means.
Occupational inequality greatly affects the socioeconomic status of an individual which is linked with their access to resources like finding a job, buying a house, etc. [4] If an individual experiences occupational inequality, it may be more difficult for them to find a job, advance in their job, get a loan or buy a house.
