The report supplements official statistics on income inequality by comparing income measures used in official statistics with income measures that include personal owners’ share of retained earnings in limited liability companies, in the same way as in Aaberge et al. (2020).
The concentration of personal market income is described by top income shares, i.e., the share of total market income that has accrued to the top X percent in the distribution of personal market income (for X equal to 10, 1, and 0.1). The development in income inequality is described by Gini coefficients for equivalized household disposable income; we start from each household’s total post-tax income and account for economies of scale in consumption by adjusting total household income for the household’s consumption needs (as proxied by measures of household size and composition).
