SOURCES
GINI index: World Bank (estimate)
“Gini index measures the extent to which the distribution of income (or, in some cases, consumption expenditure) among individuals or households within an economy deviates from a perfectly equal distribution. A Lorenz curve plots the cumulative percentages of total income received against the cumulative number of recipients, starting with the poorest individual or household. The Gini index measures the area between the Lorenz curve and a hypothetical line of absolute equality, expressed as a percentage of the maximum area under the line.”
“Data are based on primary household survey data obtained from government statistical agencies and World Bank country departments.”
Gini index of 0 represents perfect equality, while an index of 100 implies perfect inequality.
Poverty rate with poverty line at 50%: OECD
OECD: Social Protection and Well-being > Income Distribution and Poverty
Poverty rate after taxes and transfers (using new 2012 income definition). All data from 2019 and 2020 except for Italy and Japan (2018).
P90/P10: OECD
Social Protection and Well-being > Income Distribution and Poverty
The P90/P10 ratio is the ratio of the upper bound value of the ninth decile (i.e. the 10% of people with highest income) to that of the upper bound value of the first decile. All data from 2019-2020 except Italy, Japan (2018).
Percent of population below the poverty line: CIA World Factbook
*Definitions of poverty vary among nations, poverty line is drawn differently for each country.
Income Inequality S80/S20: Quintile Ratio
The quintile ratio compares the average income of the top 20% with the bottom 20%, a smaller number indicates a small difference between the two. For 2019-2020 except Italy, Japan (2018).

“Fewer millennials are making it into the middle class”
Tami Luhby, April 11, 2019
CNN Business. The middle-class is not just shrinking in the U.S. but also in other developed countries, according to a report by the OECD. Millennials are finding it increasingly difficult to achieve middle-class status compared to previous generations.
“The share of people in middle-income households in developed countries fell from 64% in the mid-1980s to only 61% by the mid-2010s. However the declines were larger in several countries, including the United States, Israel, Germany, Canada, Finland and Sweden.”
