The data in Table 2.1 compares the extent of regional income disparities across select OECD countries. The 80:50 ratio measures the gap between the 80th percentile (the regional disposable income level that only 20% of the country's regions exceed) and the median (the 50th percentile). The 50:20 ratio measures the gap between the median and the 20th percentile (the regional income level below which only 20% of the country's regions fall).
