Wood Mackenzie forecasts annual real GDP (US$) and GDP growth to the year 2035 for more than 180 economies. Forecasts are updated on a quarterly basis. This report contains an excel download of our complete Global GDP dataset. Short term GDP is forecast using a combination of lead indicators and an assessment of key economic variables over the current business cycle including monetary and fiscal policy drivers. The long term growth potential of an economy is underpinned by three structural drivers: (i) demographics; (ii) investment/ growth in capital stock; and (iii) productivity growth. We forecast long term GDP by assessing these structural supply side drivers using a set of proprietary GDP models developed by Wood Mackenzie.
