How much the acknowledged income of the top 10% is higher than the lowest 10% (so 6,7 means the top 10% have nearly 7 times the income - not wealth! - of the lower 10% of incomes in terms of households of the country. Top income households are typically smaller - in terms of persons per household, not in terms of square meter per household -, so if you look at it from a per person view it will be even worse from our perspective)
Always good to have a look at stuff like Gini coefficients (which are a bad indicator, but not useless): https://de.wikipedia.org/wiki/Liste_der_Länder_nach_Einkommensverteilung
