Two ways to see the same gap. "YoY" shows each year's reported inflation rate side by side. "Cumulative" indexes each series to 100 at its own start year and compounds forward, so each country's price level is shown relative to its own first available year (the series start years differ — see below). Toggle additional countries on/off using the pills above the chart. Hover the chart for a year-by-year crosshair. ShadowStats only exists from 1980 onward (the year the methodology is anchored to). Official CPI goes back to 1913 (BLS series start). Eurozone HICP starts 1996; Japan CPI 1960; China CPI 1987; Taiwan CPI 1981; Hong Kong Composite CPI 1981.
