This annex contains data on key economic series which provide a background to the recent economic developments in the global economy described in the main body of the OECD Economic Outlook. Data in some of the tables have been adjusted to conform to internationally agreed concepts and definitions in order to make them more comparable cross countries, as well as consistent with historical data shown in other OECD publications. Regional aggregates are based on time-varying weights.
For details on aggregation, see OECD Economic Outlook Sources and Methods.
The OECD projection methods and underlying statistical concepts and sources are described in detail in OECD Economic Outlook Sources and Methods.

Note on quarterly projections: OECD quarterly projections are on a seasonal and working-day-adjusted basis for selected key variables. This implies that differences between adjusted and unadjusted annual data may occur, though these in general are quite small. In some countries, official forecasts of annual figures do not include working-day adjustments. Even when official forecasts do adjust for working days, the size of the adjustment may in some cases differ from that used by the OECD.
