Income distribution has always been a central concern of economic theory and economic policy. Classical economists such as Adam Smith, Thomas Malthus and David Ricardo were mainly concerned with factor income distribution, that is, the distribution of income between the main factors of production, land, labour and capital.
In March 2018, the CBO reported that the ACA had reduced income inequality in 2014, saying that the law led the lowest and second quintiles (the bottom 40%) to receive an average of an additional $690 and $560 respectively while causing households in the top 1% to pay an additional $21,000 due mostly to the net investment income tax and the ...
While pre-tax income is the primary driver of income inequality, the less progressive tax code further increased the share of after-tax income going to the highest income groups. For example, had these tax changes not occurred, the after-tax income share of the top 0.1% would have been approximately 4.5% in 2000 instead of the 7.3% actual figure.
The Lorenz curve is a probability plot (a P–P plot) comparing the distribution of a variable against a hypothetical uniform distribution of that variable. It can usually be represented by a function L ( F ), where F , the cumulative portion of the population, is represented by the horizontal axis, and L , the cumulative portion of the total ...
In economics, income distribution covers how a country's total GDP is distributed amongst its population. [1] 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. [2] [3]

The Atkinson index is defined as: (, …,) = {(=) / (=) / = (,...,) = +where is individual income (i = 1, 2, ..., N) and is the mean income.. In other words, the Atkinson index is the complement to 1 of the ratio of the Hölder generalized mean of exponent 1−ε to the arithmetic mean of the incomes (where as usual the generalized mean of exponent 0 is interpreted as the geometric mean).
The x axis of the graph shows the percentiles of the global income distribution. The y axis shows the cumulative growth rate percentage of income. [1] The main conclusion that can be drawn from the graph is that the global top 1% experienced around a 60% increase in income, whereas the income of the global middle increased 70 to 80%.
