This annex contains data on key economic series which provide a background to the recent economic developments in the OECD area described in the main body of this report. Data for 2016 to 2018 are OECD estimates and projections. Data in some of the tables have been adjusted to conform to internationally agreed concepts and definitions in order to make them more comparable across 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.
