Income distribution in the context of "Accounting profit"

The median income is the income amount that divides a population into two groups, half having an income above that amount, and half having an income below that amount. It may differ from the mean (or average) income. Both of these are ways of understanding income distribution. Median income can be calculated by household income, by personal income, or for specific demographic groups. When taxes and mandatory contributions are subtracted from income, the result is called net or disposable income. The measurement of income from individuals and households, which is necessary to produce statistics such as the median, can pose challenges and yield results inconsistent with aggregate national accounts data. For example, an academic study on the Census income data claims that when correcting for underreporting, U.S. median gross household income was 15% higher in 2010 (table 3).

Profit, in accounting, is an income distributed to the owner in a profitable market production process (business). Profit is a measure of profitability which is the owner's major interest in the income-formation process of market production. There are several profit measures in common use.

Income formation in market production is always a balance between income generation and income distribution. The income generated is always distributed to the stakeholders of production as economic value within the review period. The profit is the share of income formation the owner is able to keep to themselves in the income distribution process. Profit is one of the major sources of economic well-being because it means incomes and opportunities to develop production. The words "income", "profit" and "earnings" are synonyms in this context.

The labour movement is the collective organisation of working people to further their shared political and economic interests. It consists of the trade union or labour union movement, as well as political parties of labour. It can be considered an instance of class conflict.

• In trade unions, workers campaign for higher wages, better working conditions and fair treatment from their employers, and through the implementation of labour laws, from their governments. They do this through collective bargaining, sectoral bargaining, and when needed, strike action. In some countries, co-determination gives representatives of workers seats on the board of directors of their employers.

• Political parties representing the interests of workers campaign for labour rights, social security and the welfare state. They are usually called a labour party (in English-speaking countries), a social democratic party (in Germanic and Slavic countries), a socialist party (in Romance countries), or sometimes a workers' party.
• Though historically less prominent, the cooperative movement campaigns to replace capitalist ownership of the economy with worker cooperatives, consumer cooperatives, and other types of cooperative ownership. This is related to the concept of economic democracy.

The labour movement developed as a response to capitalism and the Industrial Revolution of the late 18th and early 19th centuries, at about the same time as socialism. The early goals of the movement were the right to unionise, the right to vote, democracy, safe working conditions and the 40-hour week. As these were achieved in many of the advanced economies of Western Europe and North America in the early decades of the 20th century, the labour movement expanded to issues of welfare and social insurance, wealth distribution and income distribution, public services like health care and education, social housing and in some cases common ownership.

In welfare economics and social choice theory, a social welfare function—also called a social ordering, ranking, utility, or choice function—is a function that ranks a set of social states by their desirability. Each person's preferences are combined in some way to determine which outcome is considered better by society as a whole. It can be viewed as mathematically formalizing Rousseau's idea of a general will.

Social welfare functions are studied by economists as a way to identify socially optimal decisions, giving a procedure to rigorously define which of two outcomes should be considered better for society as a whole (e.g., to compare two different possible income distributions). They are also used by democratic governments to choose between several options in elections, based on the preferences of voters; in this context, a social choice function is typically referred to as an electoral system.

The distribution of wealth is a comparison of the wealth of various members or groups in a society. It shows one aspect of economic inequality or economic heterogeneity.

The distribution of wealth differs from the income distribution in that it looks at the economic distribution of ownership of the assets in a society, rather than the current income of members of that society. According to the International Association for Research in Income and Wealth, "the world distribution of wealth is much more unequal than that of income."

In economics, the consumption distribution or consumption inequality is an alternative to the income distribution or wealth distribution for judging economic inequality, comparing levels of consumption or spending rather than income or wealth. This is an important measure of inequality as the basic utility of the wealth or income is the expenditure. People experience the inequality directly in consumption, rather than income or wealth. World Bank lists 118 countries based on consumption inequality compared to 68 countries based on income inequality.

In economics, the Gini coefficient (/ˈdʒiːni/ JEE-nee), also known as the Gini index or Gini ratio, is a measure of statistical dispersion intended to represent the income inequality, the wealth inequality, or the consumption inequality within a nation or a social group. It was developed by Italian statistician and sociologist Corrado Gini.

The Gini coefficient measures the inequality among the values of a frequency distribution, such as income levels. A Gini coefficient of 0 reflects perfect equality, where all income or wealth values are the same. In contrast, a Gini coefficient of 1 (or 100%) reflects maximal inequality among values, where a single individual has all the income while all others have none.
