The distribution of wealth is a comparison of the wealth of various members or groups in a society. It differs from the distribution of income in that it looks at the distribution of ownership of the assets in a society, rather than the current income of members of that society.

Wealth is a person's net worth, expressed as:
The word "wealth" is often confused with "income". These two terms describe different but related things. Wealth consists of those items of economic value that an individual owns, while income is an inflow of items of economic value. (See Stock and flow.) The relation between wealth, income, and expenses is:
- change of wealth = income − expense.
A common mistake made by people embarking on a research project to determine the distribution of wealth is to use statistical data of income to describe the distribution of wealth. The distribution of income is substantially different from the distribution of wealth. According to the International Association for Research in Income and Wealth, "the world distribution of wealth is much more unequal than that of income."1
If an individual has a large income but also large expenses, her or his wealth could be small or even negative.
There are many ways in which the distribution of wealth can be analyzed. One example is to compare the wealth of the richest one percent with the wealth of the median (or 50th) percentile. In many societies, the richest ten percent control more than half of the total wealth. Mathematically, a Pareto distribution has often been used to quantify the distribution of wealth, since it models an unequal distribution.
Wealth Over People (WOP) Curves are a visually compelling way to show the distribution of wealth in a nation. WOP curves are modified Distribution of Wealth curves. The vertical and horizontal scales each show percentages from zero to one hundred. We imagine all the households in a nation being sorted from richest to poorest. They are then shrunk down and lined up (richest at the left) along the horizontal scale. For any particular household, its point on the curve represents how their wealth compares (as a %) to the average wealth of the richest percentile. For any nation, the average wealth of the richest 1/100 of households is the topmost point on the curve (People = 1%, Wealth = 100%) or (p=1, w=100) or (1,100). In the real world two points on the WOP curve are always known before any statistics are gathered. These are the topmost point (1,100) by definition, and the rightmost point (poorest people, lowest wealth) or (p=100,w=0) or (100,0). This unfortunate rightmost point is given because there are always at least one percent of households (incarcerated, long term illness, etc) with no wealth at all. Given that the topmost and rightmost points are fixed . . .our interest lies in the form of the WOP curve between them. There are two extreme possible forms of the curve. The first is the “Perfect Communist” WOP. It is a straight line from the leftmost (maximum wealth) point horizontally across the people scale to p=99. Then it drops vertically to wealth = 0 at (p=100,w=0). The other extreme is the “Perfect Tyranny” form. It starts on the left at the Tyrant’s maximum wealth of 100%. It then immediately drops to zero at p=2, and continues at zero horizontally across the rest of the people. That is, the tyrant and his friends (the top percentile) own all the nation’s wealth. All other citizens are serfs or slaves. An obvious intermediate form is a straight line connecting the left/top point to the right/bottom point. In such a “Diagonal” society a household in the richest percentile would have just twice the wealth of a family in the median (50th) percentile. Such a society is compelling to many (especially the poor). In fact it is a comparison to a diagonal society that is the basis for the “Gini Values” used as a measure of the “Disequity” in a particular economy. These Gini values (40.8 in 2007) show the United States to be the third most dis-equitable economy of all the developed nations (behind Denmark and Switzerland). The US WOP Curve is shown below. As you will see it approaches the "Tyrant's Curve". A curve that is visually appealing is the "Quarter Circle Curve" or the "Wagon Wheel WOP". Some reformers feel that any nation's tax system should be set up so that its WOP never gets sucked in beyond the Wagon Wheel form.
More sophisticated models have also been proposed.4
In many societies, attempts have been made, through property redistribution, taxation, or regulation, to redistribute wealth, sometimes in support of the upper class, and sometimes to diminish extreme inequality.
Examples of this practice go back at least to the Roman republic in the third century B.C.,6 when laws were passed limiting the amount of wealth or land that could be owned by any one family. Motivations for such limitations on wealth include the desire for equality of opportunity, a fear that great wealth leads to political corruption, to the belief that limiting wealth will gain the political favor of a voting bloc, or fear that extreme concentration of wealth results in rebellion. 7 Various forms of socialism attempt to diminish the unequal distribution of wealth and thus the conflicts and social problems (see image below) arising from it.8
During the Age of Reason, Francis Bacon wrote "Above all things good policy is to be used so that the treasures and monies in a state be not gathered into a few hands... Money is like fertilizer, not good except it be spread."9
Communism arose as a reaction to a distribution of wealth in which a few lived in luxury while the masses lived in extreme poverty. In The Communist Manifesto Marx and Engels wrote "From each according to his ability, to each according to his need."10 While the ideas of Marx have been embraced by various states (Russia, Cuba, Vietnam and China in the 20th century), Marxist utopia remains elusive.11
On the other hand, the combination of labor movements, technology, and social liberalism has diminished extreme poverty in the developed world today, though extremes of wealth and poverty continue in the Third World.12
In addition to government efforts to redistribute wealth, the tradition of individual charity is a voluntary means of wealth transference. There are also many voluntary charitable organizations making concerted efforts to aid those in need.
Many countries have national wealth surveys, for example:
- The British Wealth and Assets Survey
- The Italian Survey on Household Income and Wealth
- The US Survey of Consumer Finances
- Canada Survey of Financial Security

At the end of the 20th century, wealth was concentrated among the G8 and Western industrialized nations, along with several Asian and OPEC nations. An Energy Information Administration report stated that OPEC member nations were projected to earn $1.251 trillion in 2008, from their oil exports, due to the record crude prices.15
A study by the World Institute for Development Economics Research at United Nations University reports that the richest 1% of adults alone owned 40% of global assets in the year 2000, and that the richest 10% of adults accounted for 85% of the world total. The bottom half of the world adult population owned 1% of global wealth.16 Moreover, another study found that the richest 2% own more than half of global household assets.17
While sizeable numbers of households own no land, few have no income. For example, 10% of land owners (all corporations) in Baltimore, Maryland own 58% of the taxable land value. The bottom 10% of those who own any land own less than 1% of the total land value.18 This form of Gini coefficient analysis has been used to support Land value taxation.
According to the Congressional Budget Office, between 1979 and 2007 incomes of the top 1% of Americans grew by an average of 275%. During the same time period, the 60% of Americans in the middle of the income scale saw their income rise by 40%. Since 1979 the average pre-tax income for the bottom 90% of households has decreased by $900, while that of the top 1% increased by over $700,000, as federal taxation became less progressive.
Political factors that led to top tax rate cuts —such as those by Reagan and Thatcher in the 1980's in the United States and the United Kingdom - where accompanied by other legislative changes, such as deregulation, which may have caused top incomes to rise, not least on account of the impetus they gave to the growth of the financial services...and legal services sector.20
From 1992-2007 the top 400 income earners in the U.S. saw their income increase 392% and their average tax rate reduced by 37%.21 In 2009, the average income of the top 1% was $960,000 with a minimum income of $343,927.222324
In 2007 the richest 1% of the American population owned 34.6% of the country's total wealth, and the next 19% owned 50.5%. The top 20% of Americans owned 85% of the country's wealth and the bottom 80% of the population owned 15%. From 1922 to 2010, the share of the top 1% varied from 19.7% to 44.2%, the big drop being associated with the drop in the stock market in the late 1970s. Ignoring the period where the stock market was depressed (1976-1980) and the period when the stock market was overvalued (1929), the share of wealth of the richest 1% remained extremely stable, at about a third of the total wealth.25 Financial inequality was greater than inequality in total wealth, with the top 1% of the population owning 42.7%, the next 19% of Americans owning 50.3%, and the bottom 80% owning 7%.26 However, after the Great Recession which started in 2007, the share of total wealth owned by the top 1% of the population grew from 34.6% to 37.1%, and that owned by the top 20% of Americans grew from 85% to 87.7%. The Great Recession also caused a drop of 36.1% in median household wealth but a drop of only 11.1% for the top 1%, further widening the gap between the 1% and the 99%.192526 During the economic expansion between 2002 and 2007, the income of the top 1% grew 10 times faster than the income of the bottom 90%. In this period 66% of total income gains went to the 1%, who in 2007 had a larger share of total income than at any time since 1928.
Top 1% incomes grew by 31.4% while bottom 99% incomes grew only by 0.4% from 2009 to 2012. Hence, the top 1% captured 95% of the income gains in the first three years of the recovery.27
Dan Ariely and Michael Norton show in a study (2011) that US citizens across the political spectrum significantly underestimate the current US wealth inequality and would prefer a more egalitarian distribution of wealth, raising questions about ideological disputes over issues like taxation and welfare.28
