Distribution of Wealth

The distribution of wealth is a fundamental concept in economics that examines how wealth is spread across different members or groups within a society. Wealth distribution provides insights into one aspect of economic inequality. It differs from income distribution, which focuses on the dispersion of income rather than the ownership of assets.

Wealth vs. Income

While income refers to the flow of money received, often measured on a monthly or annual basis, wealth encompasses the total value of all assets owned by an individual or group. This includes tangible assets like property and intangible ones like stocks and bonds. An individual may have a high income but if expenses are equally high, their overall wealth may remain low or even negative. Conversely, someone with modest income but significant assets can have substantial wealth.

Measuring Wealth Distribution

One common approach to analyzing wealth distribution is to examine the ratio of wealth at different percentiles of the population. For instance, comparing the wealth of the 99th percentile to that of the median (50th percentile) can provide insights into the concentration of wealth. This is sometimes referred to as the Kuznets ratio, named after economist Simon Kuznets, who theorized about the relationship between inequality and income per capita.

Another prevalent measure is the proportion of total wealth held by the top 1% of the population, often used in discussions of the economic elite or the wealthy class.

Global Wealth Distribution

The distribution of wealth varies significantly across different countries and regions. For example, wealth inequality in the United States has markedly increased since the late 1980s. In contrast, wealth distribution in Europe often shows different patterns due to variations in social policies and economic structures.

A comprehensive overview can be found by examining the wealth distribution by country, as well as the list of sovereign states by wealth inequality, which often includes metrics like the Gini coefficient.

Redistribution of Wealth

The concept of redistribution of income and wealth involves transferring wealth from some individuals to others, typically through mechanisms like taxation and welfare programs. Redistribution aims to reduce inequality by providing resources to those with less wealth.

The Pareto Principle

The Pareto distribution is an economic concept often applied to wealth distribution. Originating from the work of Vilfredo Pareto, it suggests that a small percentage of the population controls a large portion of total wealth, leading to a skewed distribution that is prevalent across various societies.
