Data Definitions & Discrepancies
This dashboard displays macroeconomic data from multiple countries. Please be aware of the following cross-country methodological differences:
-
CPI (Consumer Price Index):
- US & UK: Generally focus on core CPI or specific baskets adjusted frequently.
- China: The basket has a higher weighting on food (especially pork) and is adjusted less frequently.
-
Unemployment Rate:
- US: Based on broad household surveys (U-3 is the official rate, U-6 includes underemployed).
- China: Primarily tracks the Urban Surveyed Unemployment Rate, which may not fully capture rural or migrant workforce fluctuations.
-
Commodities (Units):
- US (WTI Crude): Priced in USD per barrel (bbl).
- China (Iron Ore): Priced in CNY per metric ton (MT) on the Dalian Commodity Exchange.
These discrepancies mean that direct 1:1 comparisons of absolute values (especially indices) across countries are not always applicable. We recommend comparing the trends and percentage changes rather than the nominal values.
