Notes: HH equivalized disposable household income. CI concentration index. ACI absolute concentration index. SCI standardized concentration index. SACI standardized absolute concentration index. GDP gross domestic product. PPS purchasing power standard. Regression coefficients which differ significantly from zero (at p < 0.05) are in bold typeface. Each row represents four different bivariate linear regressions.
*p < 0.10 **p < 0.05 ***p < 0.01.
