How This Is Calculated

Based on the official consumer price index (CPI) for this country — for the US, the Bureau of Labor Statistics' CPI-U, averaged from monthly figures to a single annual value; for Korea and Japan, the World Bank's annual CPI series. A gap in the source data is shown as a gap, never estimated or interpolated.
