In economics, the Gini coefficient, 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.
In economics, the Lorenz curve is a graphical representation of the distribution of income or of wealth. It was developed by Max O. Lorenz in 1905 for representing inequality of the wealth distribution.
A regressive tax is a tax imposed in such a manner that the tax rate decreases as the amount subject to taxation increases. "Regressive" describes a distribution effect on income or expenditure, referring to the way the rate progresses from high to low, so that the average tax rate exceeds the marginal tax rate.
Economic inequality is an umbrella term for a) income inequality or distribution of income, b) wealth inequality or distribution of wealth, and c) consumption inequality. Each of these can be measured between two or more nations, within a single nation, or between and within sub-populations.
In economics, income distribution covers how a country's total GDP is distributed amongst its population. Economic theory and economic policy have long seen income and its distribution as a central concern. Unequal distribution of income causes economic inequality which is a concern in almost all countries around the world.
Income inequality metrics or income distribution metrics are used by social scientists to measure the distribution of income and economic inequality among the participants in a particular economy, such as that of a specific country or of the world in general. While different theories may try to explain how income inequality comes about, income inequality metrics simply provide a system of measurement used to determine the dispersion of incomes. The concept of inequality is distinct from poverty and fairness.
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.
Household income is an economic standard that can be applied to one household, or aggregated across a large group such as a county, city, or the whole country. It is commonly used by the United States government and private institutions to describe a household's economic status or to track economic trends in the US.
In economics, personal income refers to the total earnings of an individual from various sources such as wages, investment ventures, and other sources of income. It encompasses all the products and money received by an individual.
Affluence refers to an individual's or household's economical and financial advantage in comparison to others. It may be assessed through either income or wealth.
In economics, distribution is the way total output, income, or wealth is distributed among individuals or among the factors of production. In general theory and in for example the U.S. National Income and Product Accounts, each unit of output corresponds to a unit of income. One use of national accounts is for classifying factor incomes and measuring their respective shares, as in national Income. But, where focus is on income of persons or households, adjustments to the national accounts or other data sources are frequently used. Here, interest is often on the fraction of income going to the top x percent of households, the next x percent, and so forth, and on the factors that might affect them.
Income inequality has fluctuated considerably in the United States since measurements began around 1915, moving in an arc between peaks in the 1920s and 2000s, with a 30-year period of relatively lower inequality between 1950 and 1980.
Income segregation is the separation of various classes of people based on their income. For example, certain people cannot get into country clubs because of insufficient funds. Another example of income segregation in a neighborhood would be the schools, facilities and the characteristics of a population. Income segregation can be illustrated in countries such as the United States, where racial segregation is a major cause of income inequality.
Income in India discusses the financial state in India. With rising economic growth and India's income is also rising rapidly. As an overview, India's per capita net national income or NNI was around Rs. 98,374 in 2022-23. The per-capita income is a crude indicator of the prosperity of a country. In contrast, the gross national income at constant prices stood at over 128 trillion rupees. According to a 2021 report by the Pew Research Center, India has roughly 1.2 billion lower-income individuals, 66 million middle-income individuals, 16 million upper-middle-income individuals, and barely 2 million in the high-income group. According to The Economist, 78 million of India's population are considered middle class as of 2017, if defined using the cutoff of those making more than $10 per day, a standard used by the India's National Council of Applied Economic Research. According to the World Bank, 93% of India's population lived on less than $10 per day, and 99% lived on less than $20 per day in 2021.
Social inequality occurs when resources within a society are distributed unevenly, often as a result of inequitable allocation practices that create distinct unequal patterns based on socially defined categories of people. Differences in accessing social goods within society are influenced by factors like power, religion, kinship, prestige, race, ethnicity, gender, age, sexual orientation, intelligence and class. Social inequality usually implies the lack of equality of outcome, but may alternatively be conceptualized as a lack of equality in access to opportunity.
The inequality of wealth has substantially increased in the United States in recent decades. Wealth commonly includes the values of any homes, automobiles, personal valuables, businesses, savings, and investments, as well as any associated debts.
China's current mainly market economy features a high degree of income inequality. According to the Asian Development Bank Institute, "before China implemented reform and opening-up policies in 1978, its income distribution pattern was characterized as egalitarian in all aspects."
Socioeconomic mobility in the United States refers to the upward or downward movement of Americans from one social class or economic level to another, through job changes, inheritance, marriage, connections, tax changes, innovation, illegal activities, hard work, lobbying, luck, health changes or other factors.
