Wat geeft de Lorenz-curve weer?

Wat geeft de Lorenz-curve weer?

De Lorenzcurve is een grafiek die laat zien hoe het totale inkomen van een land verdeeld is over de bevolking. De lijn begint altijd in de oorsprong (0% van het inkomen wordt verdiend door 0% van de mensen) en eindigt altijd op het punt waar 100% van het inkomen wordt verdiend door 100% van de mensen.

Wat betekent een hoge Gini Coefficient?

De Gini-coëfficiënt neemt altijd een getal tussen de 0 en de 1 aan. Hoe dit getal berekend wordt, hoef je niet precies te weten. Wat je wel moet weten is dat hoe hoger dit getal is, des te ongelijker het land is aangaande inkomensverdeling.

What is the highest value of a Gini coefficient?

The coefficient ranges from 0 (or 0%) to 1 (or 100%), with 0 representing perfect equality and 1 representing perfect inequality. Values over 1 are theoretically possible due to negative income or wealth. The Gini index is a measure of the distribution of income across a population.

How are Gini coeficients calculated?

Organize the data into a table with the category head mentioned below.

Fill ‘% of Population that is richer’ column by adding all terms in ‘Fraction of Population’ below that row.

Calculate the Score for each of the rows.

Next,add all the terms in the ‘Score’ column.

The Gini coefficient of 2 countries based on the income of citizens is as under.

How does the Gini ratio relate to the Lorenz curve?

This curve is called the “line of perfect inequality.”. The Gini coefficient is the ratio of the area between the line of perfect equality and the observed Lorenz curve to the area between the line of perfect equality and the line of perfect inequality. The higher the coefficient, the more unequal the distribution is.

Does the Lorenz curve really measure inequality?

Lorenz curves, along with their derivative statistics, are widely used to measure inequality across a population. Because Lorenz curves are mathematical estimates based on fitting a continuous curve to incomplete and discontinuous data, they may be imperfect measures of true inequality .
