Figure A1. Middle-class household income
Top lines: 75th percentile. Middle lines: 50th percentile. Bottom lines: 25th percentile. Thick lines: Luxembourg Income Study (LIS) data. Thin lines: OECD data. Posttransfer-posttax household income. The incomes are adjusted for household size and then rescaled to reflect a three-person household, adjusted for inflation, and converted to US dollars using purchasing power parities. “k” = thousand.
