Her expertise covers a wide range of accounting, corporate finance, taxes, lending, and personal finance areas. {\displaystyle r_{j}=x_{j}/{\overline {x}}} {\displaystyle r_{j}=1} Because the Gini attempts to distill a two-dimensional area (the gap between the Lorenz curve and the equality line) down to a single number, it obscures information about the shape of inequality. The Gini index is also related to the Pietra index both of which measure statistical heterogeneity and are derived from the Lorenz curve and the diagonal line. [58] For example, in social sciences and economics, in addition to income Gini coefficients, scholars have published education Gini coefficients and opportunity Gini coefficients. (Note that this formula can be applied when there are negative values if the integration is taken from minus infinity to plus infinity. Inequality is generally lower in Europe than elsewhere in the world, and the Gini coefficient offers quantifiable proof of that fact. Shadow economies and informal economic activity are present in every country. j For example, if y follows a log-normal distribution with the standard deviation of logs equal to (Eds.). For example, suppose two equally egalitarian countries pursue different immigration policies. The Gini coefficient calculated from a sample is a statistic, and its standard error, or confidence intervals for the population Gini coefficient, should be reported. Organisation for Economic Co-operation and Development. For example, five 20% quantiles (low granularity) will usually yield a lower Gini coefficient than twenty 5% quantiles (high granularity) for the same distribution. Results indicated that although decreasing overall, home computer ownership inequality was substantially smaller among white households.[102]. 1 However, the Gini impurity for a set of labels ($J$ many labels) is the sum of this $p_{i}(1-p_{i})$ term across all labels, which simplifies to $1-\sum_{i=1}^{J}{p_{i}^{2}}$. If (Xk, Yk) are the known points on the Lorenz curve, with the Xk indexed in increasing order (Xk 1 < Xk), so that: If the Lorenz curve is approximated on each interval as a line between consecutive points, then the area B can be approximated with trapezoids and: is the resulting approximation for G. More accurate results can be obtained using other methods to approximate the area B, such as approximating the Lorenz curve with a quadratic function across pairs of intervals or building an appropriately smooth approximation to the underlying distribution function that matches the known data. This trend appears to have peaked and begun a reversal with rapid economic growth in emerging economies, particularly in the large populations of BRIC countries. There is still ongoing debate surrounding this topic. where WebGini index. I have been using entropy so far (calculated this way): Now I want to implement a function that calculates the Gini index of an array. {\displaystyle f(y_{i})} Though India's education Gini Index has been falling from 1960 through 1990, most of the population still has not received any education, while 10 percent of the population received more than 40% of the total educational hours in the nation. WebGini index - United States. Similar in concept to the Gini income coefficient, the Gini opportunity coefficient measures inequality in opportunities. He is a CFA charterholder as well as holding FINRA Series 7, 55 & 63 licenses. Over recent decades, Hong Kong has witnessed increasing numbers of small households, elderly households, and elderly living alone. Gini index measures the extent to which the distribution of Wealthy countries such as Sweden can show a low Gini coefficient for the disposable income of 0.31, thereby appearing equal, yet have a very high Gini coefficient for wealth of 0.79 to 0.86, suggesting an extremely unequal wealth distribution in its society. That said, in 2005, the Gini coefficient was even higher, at 65.0. 2 is the error function ( since Defining as the mean of the distribution, and specifying that F(y) is zero for all negative values, the Gini coefficient is given by: The latter result comes from integration by parts. Facebook. You can learn more about the standards we follow in producing accurate, unbiased content in our. Gross domestic product is the monetary value of all finished goods and services made within a country during a specific period. According to UNICEF, Latin America and the Caribbean region had the highest net income Gini index in the world at 48.3, on an unweighted average basis in 2008. By {\displaystyle y_{i}>0} {\displaystyle \textstyle \mu =\int _{-\infty }^{\infty }xp(x)\,dx} [68], A 2010 study using social security income data for the United States since 1937 and Gini-based Shorrock's indices concludes that income mobility in the United States has had a complicated history, primarily due to the mass influx of women into the American labor force after World War II. x Gini Index around 2015 vs. Gini Index around 2000. The United States has a Gini co-efficient of 41.1, which is a high reading for such a developed economy. Gini Index of Money Income Informal economy accounts for over half of global employment and as much as 90 per cent of employment in some of the poorer sub-Saharan countries with high official Gini inequality coefficients. Knowing the Gini index numbers is no panacea, but this measure does provide a way to quantify and track the direction in which a society is moving, which may open the door for dialogue and potential solutions. countries may have identical Gini coefficients, but differ greatly in wealth. WebThe Gini coefficient is a well-understood measure of inequality . These indicators are related to Gini. The Gini is based on the comparison of cumulative proportions of the population against cumulative proportions of income they receive.[71]. The Gini co-efficient is equal to the area below the line of perfect equality (0.5 by definition) minus the area below the Lorenz curve, divided by the area below the line of perfect equality. [59] It is used to discern trends in social development through educational attainment over time. [60]. Adam Hayes, Ph.D., CFA, is a financial writer with 15+ years Wall Street experience as a derivatives trader. For example, (taking y to indicate the income or wealth of a person or household): Since the Gini coefficient is half the relative mean absolute difference, it can also be calculated using formulas for the relative mean absolute difference. These include wealth taxes in medieval European city states, patterns of landownership in Roman Egypt, variation of the size of houses in societies from ancient Greece to Aztec Mexico, and inheritance and dowries in Babylonian society. [6] For OECD countries in the late 20th century, considering the effect of taxes and transfer payments, the income Gini coefficient ranged between 0.24 and 0.49, with Slovenia being the lowest and Mexico the highest. Our World In Data is a project of the Global Change Data Lab, a registered charity in England and Wales (Charity Number 1186433). p 208, 7379. C It only takes a minute to sign up. Kaminskiy and Krivtsov[106] extended the concept of the Gini coefficient from economics to reliability theory and proposed a Ginitype coefficient that helps to assess the degree of aging of nonrepairable systems or aging and rejuvenation of repairable systems. Because of data and other limitations, the Gini index may overstate income inequality and can obscure important information about income distribution. From here I get the following function that calculates: But from this other source I see that the Gini impurity can be calculated, $ G = \sum_i^n \cdot p(i) \cdot (1-p(i))$. ) 1 This function has the following properties: L (0)=0,L (1)=1, L' (r) \ge 0 and L ( r) is a convex function. Formula, and Coefficient. This detailed guide helps you learn everything upon Gini index form, how till calculate Gini index, Jenni register making tree, Gini browse sample real more! ) An example case in which the wealthiest 20% of the population has 80% of all income (see Pareto principle) would lead to an income Gini coefficient of at least 60%. Citing my unpublished master's thesis in the article that builds on top of it. for everyone). A country in which every resident has the same income would have an income Gini co-efficient of 0. If xi is the wealth or income of person i, and there are n persons, then the Gini coefficient G is given by: When the income (or wealth) distribution is given as a continuous probability density function p(x), the Gini coefficient is again half of the relative mean absolute difference: where = If you continue to navigate this website beyond this page, cookies will be placed on your browser. + {\displaystyle 1/\lambda } Since the Gini coefficient is independent of scale, if the distribution function can be expressed in the form f(x,,a,b,c) where is a scale factor and a,b,c are dimensionless parameters, then the Gini coefficient will be a function only of a,b,c.[28] For example, for the exponential distribution, which is a function of only x and a scale parameter, the Gini coefficient is a constant, equal to 1/2. As another example, in a population where the lowest 50% of individuals have no income, and the other 50% have equal income, the Gini coefficient is 0.5; whereas for another population where the lowest 75% of people have 25% of income and the top 25% have 75% of the income, the Gini index is also 0.5. Education vs. The Gini coefficient has also been applied to analyze inequality in dating apps.[104][105]. = [75] Similarly, computational social scientist Fabian Stephany illustrates that income inequality within the population, e.g., in specific socioeconomic groups of same age and education, also remains undetected by conventional Gini indices.[76]. [61][62][63] The concept builds on Amartya Sen's suggestion[64] that inequality coefficients of social development should be premised on the process of enlarging people's choices and enhancing their capabilities, rather than on the process of reducing income inequality. WebCountry Comparisons Gini Index coefficient distribution of family income Distribution of family income - Gini index measures the degree of inequality in the distribution of family OECD Income (IDD) and Wealth (WDD) Distribution Databases.. , in the calculation section above, may be used for the final model and at the individual model factor level to quantify the discriminatory power of individual factors. For economically diverse large population groups, a much higher coefficient is expected than for each of its regions. The co-efficient is only as reliable as the data used to calculate it, and it only provides a single-digit reading, which doesnt take different groups in the sample into account. Even in affluent countries, the Gini index measures net income rather than net worth, so the majority of a nations wealth can still be concentrated in the hands of a small number of people even if income distribution is relatively equal. This was developed in an economic context to describe income distribution inequality. [14][15][16], The Gini coefficient was developed by the Italian statistician Corrado Gini and published in his 1912 paper Variabilit e mutabilit (Italian: variability and mutability). Sometimes the entire Lorenz curve is not known, and only values at certain intervals are given. ) Another limitation of the Gini coefficient is that it is not a proper measure of egalitarianism, as it only measures income dispersion. The more nearly equal a country's income distribution, the lower its Gini index, e.g., a Scandinavian country with an index of 25. {\displaystyle G=2\Phi \left({\frac {\sigma }{\sqrt {2}}}\right)-1} Because of this, factors such as age distribution within a population and mobility within income classes can create the appearance of inequality when none exist, taking into account demographic effects. Meaning, Causes, and How to Measure, Gini Index Explained and Gini Co-efficients Around the World. Nordic and Central Eastern European countries dominate this list, claiming seven of the top 10 slots. Data are based on primary household survey data obtained from government statistical agencies and World Bank country departments. As with other inequality coefficients, the Gini coefficient is influenced by the granularity of the measurements. Can a Family Survive on the US Minimum Wage? World Bank, Poverty and Inequality Platform. Incomes are more equally distributed and fewer people are poor where social spending is high: the Nordic countries and western n However, it should be borne in mind that the Gini coefficient can be misleading when used to make political comparisons between large and small countries or those with different immigration policies (see limitations section). ( A Gini Index CoefficientDistribution of Family Income.. Machine Teaching. [22], Suppose all people have non-negative income (or wealth, as the case may be). i What Is the Human Development Index (HDI)? {\displaystyle x_{j}} x A Gini coefficient of 0 reflects perfect equality, where all income or wealth values are the same, while a Gini coefficient of 1 (or 100%) reflects maximal inequality among values. Many older people live separately from their children in Hong Kong. x j [99] In engineering, it has been used to evaluate the fairness achieved by Internet routers in scheduling packet transmissions from different flows of traffic. Formula, and Coefficient. An alternative approach is to define the Gini coefficient as half of the relative mean absolute difference, which is equivalent to the definition based on the Lorenz curve. The Gini coefficient, also called the Gini index or Gini ratio, is the most commonly used measure of income distributionsimply put, the higher the Gini coefficient, the greater the gap between the incomes of a country's richest and poorest people. A country's Gini coefficient is important because it helps identify high levels of income inequality, which can have several undesirable political and economic impacts. World Bank, Poverty and Inequality Platform. [53], The table below presents the estimated world income Gini coefficients over the last 200 years, as calculated by Milanovic. The comparison is not meaningful when different populations are not measured with consistent definitions. 10, no. September 16, 2015 Share. x In a recent articlein the MONTHLY, F. Food and Agriculture Organization of the United Nations. Countries that provide subsidized housing, medical care, education or other such services are difficult to value objectively, as it depends on the quality and extent of the benefit. Data for high-income economies are mostly from the Luxembourg Income Study database. But what is actually meant 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 or the wealth inequality or the consumption inequality within a nation or a social group. j 88). Please consult our full legal disclaimer. Experience: Which One Gets the Job? The Gini Index was highest for CMNNs and lowest for NCDs. , Scholars have devised over a dozen variants of the Gini coefficient. Conversely, a country in which one resident earned all the income, while everyone else earned nothing, would have an incomeGini co-efficient of 1. The Gini coefficient measure gives different results when applied to individuals instead of households, for the same economy and same income distributions. r [45] The coefficient ranges from 0, for perfect equality, to 1, indicating perfect inequality. Additionally, due to limitations such as reliable GDP and income data, the Gini index may overstate income inequality and be inaccurate. This method only requires using ordinary least squares regression after ordering the sample data. {\displaystyle AUC=(G+1)/2} The results compare favorably with the estimates from the jackknife with agreement improving with increasing sample size.[41]. [96] In health, it has been used as a measure of the inequality of health-related quality of life in a population. Is the U.S. Gini co-efficient high or low? Note that the complement $\sum p_i^2$ is also often used. ( [10] The country with the lowest Gini coefficient is Slovenia, with 0.232. The model then expresses the rank (dependent variable) as the sum of a constant A and a normal error term whose variance is inversely proportional to yk: Thus, G can be expressed as a function of the weighted least squares estimate of the constant A and that this can be used to speed up the calculation of the jackknife estimate for the standard error. [19], The Gini coefficient is an index for the degree of inequality in the distribution of income/wealth, used to estimate how far a country's wealth or income distribution deviates from an equal distribution. The Gini coefficient (Gini index or Gini ratio) is a statistical measure of economic inequality in a population. in terms of variance, Regulations regarding taking off across the runway. They also claim education Gini index for the United States slightly increased over the 19801990 period. Data are based on primary household survey data obtained from government statistical agencies and World Bank country departments. The Gini coefficient has a geometric interpretation as twice the area between the Lorenz curve and the diagonal line r. Another popular measure is the Theil index (Theil 1967 ), which belongs to the class of entropy-based inequality measures. Word to describe someone who is ignorant of societal problems. What is the Gini Coefficient? The Gini coefficient (Gini index or Gini ratio) is a statistical measure of economic inequality in a population. The coefficient measures the dispersion of income = Based on the distribution of an outcome variable among ranked-ordered units in a population, the Gini coefficient measures the degree of inequality in the distribution of total resources. {\displaystyle G=\operatorname {erf} \left({\frac {\sigma }{2}}\right)} equals the mean income The Consumer Price Index (CPI) measures change over time in the prices paid by consumers for a representative basket of goods and services. [68] Other scholars, using just 1990s data or other short periods have come to different conclusions. Basic necessities may be available to all in a developed economy, while in an undeveloped economy with the same Gini coefficient, basic necessities may be unavailable to most or unequally available due to lower absolute wealth. For a discrete probability distribution with probability mass function A Gini coefficient of 0 expresses perfect equality, with all units receiving an equal share. The Gini coefficient is a relative measure. Between 1960 and 1990, China, India and South Korea had the fastest drop in education inequality Gini Index. WebGini Coefficient (G) = 0.28571 Cumulative Proportion of Income Cumulative Proportion of Population Reference The Gini coefficient, named for the Italian statistician Corrado Gini, represents a dimensionless measurement of statistical dispersion that is often employed to analyze income distribution. Charts Annual growth of the incomes or consumption of the poorest 40% GDP per capita vs. income inequality Gini Index around 2015 vs. Gini Index around 2000 Gini coefficient, equivalized income after tax and transfers 1 A 2016 peer-reviewed study titled Employing the Gini coefficient to measure participation inequality in treatment-focused Digital Health Social Networks[103] illustrated that the Gini coefficient was helpful and accurate in measuring shifts in inequality, however as a standalone metric it failed to incorporate overall network size. + A simplified case distinguishes just two levels of income, low and high. WebThe GINI index, also known as the GINI coefficient, is a measure of income inequality. Why aren't structures built adjacent to city walls? A more graded distribution with these same values u and f will always have a higher Gini coefficient than f u. The Gini Coefficient or Gini Index measures the inequality among the values of a variable. The Gini co-efficient experienced sustained growth during the 19th and 20th centuries. The offers that appear in this table are from partnerships from which Investopedia receives compensation. Kovacevic, in a review of the Gini opportunity coefficient, explained that the coefficient estimates how well a society enables its citizens to achieve success in life where the success is based on a person's choices, efforts and talents, not their background defined by a set of predetermined circumstances at birth, such as gender, race, place of birth, parent's income and circumstances beyond the control of that individual. By measuring inequality in income, the Gini ignores the differential efficiency of the use of household income. The Origins of the Gini Index: Extracts from Variabilit e Mutabilit (1912) by Corrado Gini, The Journal of Economic Inequality, September 2012, vol. Measuring inequality: Lorenz curves and Gini coefficients Working in Excel", "cumulative distribution function - How to compute the Wealth Lorenz curve with negative values? The United States has a Gini coefficient of 41.1. However, the relationship between income inequality and GDP per capita is not one of perfect negative correlation, and the relationship has varied over time. Income inequality and income mobility trends have been different for men and women workers between 1937 and the 2000s. y High praise, @NickCox ! World Bank, Poverty and Inequality Platform. [54], More detailed data from similar sources plots a continuous decline since 1988. {\displaystyle r_{j}=1} G [7][47][48], For OECD countries over the 20082009 period, the Gini coefficient (pre-taxes and transfers) for a total population ranged between 0.34 and 0.53, with South Korea the lowest and Italy the highest. For more information and methodology, please see, Poverty headcount ratio at national poverty lines (% of population), Poverty gap at $3.65 a day (2017 PPP) (%), Poverty headcount ratio at $2.15 a day (2017 PPP) (% of population), Multidimensional poverty headcount ratio (% of total population), Multidimensional poverty headcount ratio, male (% of male population), Multidimensional poverty index, children (population ages 0-17) (scale 0-1), Poverty headcount ratio at $6.85 a day (2017 PPP) (% of population), Multidimensional poverty headcount ratio, household (% of total households), International Comparison Program & Purchasing Power Parity, International Household Survey Network (IHSN), Trust Fund for Statistical Capacity Building.

[20], The Gini coefficient is usually defined mathematically based on the Lorenz curve, which plots the proportion of the total income of the population (y-axis) that is cumulatively earned by the bottom x of the population (see diagram). Economists blame rising income inequality in the U.S. on factors such as technological change, globalization, the decline of unions, and the eroding value of the minimum wage. It measures inequality in income without considering the effect of taxes and social spending already in place in a country. [69] For example, Sastre and Ayala conclude from their study of income Gini coefficient data between 1993 and 1998 for six developed economies that France had the least income mobility, Italy the highest, and the United States and Germany intermediate levels of income mobility over those five years. If you continue to navigate this website beyond this page, cookies will be placed on your browser. [11]The global income Gini coefficient in 2005 has been estimated to be between 0.61 and 0.68 by various sources. Schneider et al., in their 2010 study of 162 countries,[84] report about 31.2%, or about $20 trillion, of world's GDP is informal. The Gini coefficient, also known as the Gini index or the Gini ratio, was introduced in 1912 by Italian statistician and sociologist Corrado Gini. {\displaystyle \operatorname {erf} } According to The World Bank, the Gini co-efficient has increased about 1.5 points in the five years following major epidemics, such as Ebola and Zika. It represents the spread between low and high-income earners, with possible values World Population Review. , then: When the population is large, the income distribution may be represented by a continuous probability density function f(x) where f(x) dx is the fraction of the population with wealth or income in the interval dx about x. Changing income inequality, measured by Gini coefficients, can be due to structural changes in a society such as growing population (increased birth rates, aging populations, increased divorce rates, extended family households splitting into nuclear families, emigration, immigration) and income mobility. Guillermina Jasso[42] and Angus Deaton[43] independently proposed the following formula for the Gini coefficient: where According to the US Census Bureau, between 1979 and 2010, the population of the United States experienced structural changes in overall households; the income for all income brackets increased in inflation-adjusted terms, household income distributions shifted into higher income brackets over time, while the income Gini coefficient increased.[82][83]. Developed by Italian statistician Corrado Gini in 1912, the Gini coefficient ranges from 0 to 1, but is often written as a percentage. [92][93][28], In certain fields such as ecology, inverse Simpson's index Are non-string non-aerophone instruments suitable for chordal playing? Additionally, more than half of South Africa's population lives in poverty. For example, if everyone has the same income, the Gini coefficient will be 0. {\displaystyle G_{1}} If household data is used, the measured value of income Gini depends on how the household is defined. Webchart table sources Download All our related research and data Is income inequality rising around the world? [17][18] Building on the work of American economist Max Lorenz, Gini proposed that the difference between the hypothetical straight line depicting perfect equality, and the actual line depicting people's incomes, be used as a measure of inequality. Shorrocks index is calculated in several different ways, a common approach being from the ratio of income Gini coefficients between short-term and long-term for the same region or country. How does a government that uses undead labor avoid perverse incentives? Investopedia requires writers to use primary sources to support their work. "On the Measure of Concentration with Special Reference to Income and Statistics", Colorado College Publication, General Series No. In 1820, the global Gini co-efficient stood at 0.50, while in 1980 and 1992, the figure was 0.657. i x Browse other questions tagged, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site. Nov 24, 2022 9 min read. Accurate wealth data is even more difficult to come by due to the popularity of tax havens. WebThe Gini coefficient is based on the comparison of cumulative proportions of the population against cumulative proportions of income they receive, and it ranges between 0 in the case of perfect equality and 1 in the case of perfect inequality. It measures inequality in income after considering the effect of taxes and social spending already in place in a country. G Gini In everyday terms, this would be similar to describing the contents of a photo solely by its length along one edge, or the simple average brightness value of the pixels. WebThe Gini coefficient, also called the Gini index or Gini ratio, is the most commonly used measure of income distributionsimply put, the higher the Gini coefficient, the Making statements based on opinion; back them up with references or personal experience. New York: M. Dekker, page 11. And the Gini index can provide a great starting point when it comes to measuring that income inequality. i Gini Index or Gini impurity measures the degree or probability of a particular variable being wrongly classified when it is randomly chosen. = Our World in Data is free and accessible for everyone. It was developed by statistician and sociologist Corrado Gini. [7][49] Taxes and social spending that were in place in 20082009 period in OECD countries significantly lowered effective income inequality, and in general, "European countriesespecially Nordic and Continental welfare statesachieve lower levels of income inequality than other countries."[50]. A Gini of 50 marks the halfway point and can generally be perceived as a place where income is not fairly distributed. Socio-Specific Income Inequality and Trust", "Accounting for Swedish wealth inequality", "Convergence of EU regions: Measures and evolution", "A New Data Set Measuring Income Inequality", "Income, Poverty, and Health Insurance Coverage in the United States: 2010 (see Table A-2)", Congressional Budget Office: Trends in the Distribution of Household Income Between 1979 and 2007, "Is income inequality really the problem?
