The first necessary condition for the phenomenon of wealth concentration to occur is an unequal initial distribution of wealth. The distribution of wealth throughout the population is often closely approximated by a Pareto distribution, with tails which decay as a power-law in wealth. (See also: Distribution of wealth and Economic inequality).
The curve is a graph showing the proportion of overall income or wealth assumed by the bottom x% of the people, although this is not rigorously true for a finite population (see below). It is often used to represent income distribution , where it shows for the bottom x % of households, what percentage ( y %) of the total income they have.
The inequality of wealth (i.e. inequality in the distribution of assets) has substantially increased in the United States in recent decades. [2] Wealth commonly includes the values of any homes, automobiles, personal valuables, businesses, savings, and investments, as well as any associated debts. [3] [4]
The wealth analysis draws from the 2022 Survey of Consumer Finance, which found that household wealth in America swelled at a record pace during the pandemic. From 2019 to 2022, the median net ...
Household assets have skyrocketed since 1989. For Americans in the bottom half of the wealth distribution, housing made up 51% of their assets. Wealthier households, in contrast, tend to have ...
The Pareto distribution, named after the Italian civil engineer, economist, and sociologist Vilfredo Pareto, [2] is a power-law probability distribution that is used in description of social, quality control, scientific, geophysical, actuarial, and many other types of observable phenomena; the principle originally applied to describing the distribution of wealth in a society, fitting the trend ...
The Elephant Curve, also known as the Lakner-Milanovic graph or the global growth incidence curve, is a graph that illustrates the unequal distribution of income growth for individuals belonging to different income groups. [1] The original graph was published in 2013 and illustrates the change in income growth that occurred from 1988 to 2008.
Wealth inequality refers to the distribution of net worth (i.e., what is owned minus what is owed) as opposed to annual income. Wealth is affected by movements in the prices of assets, such as stocks, bonds and real estate, which fluctuate over the short-term. Income inequality has significant effects over long-term shifts in wealth inequality.
