LIS, formerly known as The Luxembourg Income Study, is a data archive and research center dedicated to cross-national analysis. LIS is home to two databases, the Luxembourg Income Study Database, and the Luxembourg Wealth Study Database. The Luxembourg Income Study Database (LIS), under constant expansion, is the largest available database of harmonised microdata collected from multiple countries over a period of decades. The newer Luxembourg Wealth Study Database (LWS), is the only cross-national wealth microdatabase in existence.

Atkinson Index is a welfare-based measure of inequality, representing the percentage of total income that a given society would have to sacrifice in order to have (more) equally distributed incomes (more equal shares of income between its citizens). This measure depends on the degree of society aversion to inequality, where a higher value entails greater social utility or willingness by individuals to accept smaller incomes in exchange for a more equal distribution. In the calculation of this variable, the aversion parameter (epsilon) is set to 0.5.

More about this variablePercentage of children living in single-mother families.

More about this variableThis variable reports the percentage of single-mother families whose income falls below the poverty line as defined as half of the median of equivalised disposable household income. In combination with decompositions, the ratio refers to the percentage of each group, whose income falls below the above defined poverty line.

More about this variableThis variable reports the percentage of two-parent families whose income falls below the poverty line as defined as half of the median of equivalised disposable household income. In combination with decompositions, the ratio refers to the percentage of each group, whose income falls below the above defined poverty line.

More about this variableThis variable reflects the percentage of children whose household income is more than 150% of the median of equivalised disposable household income. Disposable Household Income refers to cash and non-cash income from labour, income from capital, income from pensions (including private and public pensions) and non-pension public social benefits stemming from insurance, universal or assistance schemes (including in-kind social assistance transfers), as well as cash and non-cash private transfers, after deduction of the amount of income taxes and social contributions paid. Disposable Household Income is equivalised at individual level as the total amount divided by the square root of household members. Before equivalisation, top and bottom coding has been applied by setting boundaries for extreme values of log transformed Disposable Household Income: at the top Q3 plus 3 times the interquartile range (Q3-Q1), and at the bottom Q1 minus 3 times the interquartile range.

More about this variableThis variable reflects the percentage of children whose household income falls between 50% and 75% of the median of equivalised disposable household income.

More about this variableGini Index measures the extent to which the distribution of the specified aggregate among individuals or households within an economy deviates from a perfectly equal distribution. The Gini index measures the area between the Lorenz curve and the hypothetical line of absolute equality. A Gini index of zero represents perfect equality and 1, perfect inequality.

More about this variableThe mean value of the Equivalized Income. Equivalised Disposable Household Income refers to cash and non-cash income from labour, income from capital, income from pensions (including private and public pensions) and non-pension public social benefits stemming from insurance, universal or assistance schemes (including in-kind social assistance transfers), as well as cash and non-cash private transfers, after deduction of the amount of income taxes and social contributions paid.
