The financial prosperity of a household is based on both its standardised income and its assets. After ranking on the basis of income and assets, the financial wealth level of a household is determined from the sum of the cumulative share in total income and the cumulative share in total assets. Based on the addition, households were then ranked from low to high and divided into five groups of equal size (quintiles). The first quintile then contains the 20 percent of households with the lowest financial wealth, the fifth quintile contains the 20 percent of households with the highest financial wealth.
